As the request for digitalization continues to grow at an accelerated rate, more and more CIOs are putting low-code technology at the top of their priority list given the inherent strategic benefit it has in improving operational efficiency and accelerating digital transformation projects. All without requiring too much time or money invested in the development process. According to published in June 2021, low-code software development platforms are becoming increasingly popular as businesses strive to streamline workflows and digitalize. Low-code technology is already used in nearly half of the studied enterprises (47%) and one-fifth are planning to adopt a low-code platform within the next 12 months. The majority of respondents use low-code platforms to: TechRepublic research automate workflows (17%), create new apps (15%), shorten development time (15%), automate data collecting and reporting (15%), 0% of respondents mentioned reducing the burden on developers. also expect that by 2025, 70% of new enterprise apps would be built using minimal or no-code technologies, up from below 25% in 2020, as low-code has evolved to offer immediate and very high impact in enterprises. Gartner analysts This growing popularity of low-code development platforms is unsurprising, as they put process innovation tools in the hands of problem solvers, and both non-developers and developers are seeing an increase in the sophistication of the apps they can create using low-code approaches. And as more businesses discover what is possible with low-code development, the adoption of these tools will not only continue to grow but it will also become more structured. So, let’s look at 3 different low-code development approaches the LCP Market has contoured and the main things every CIO should know about them when it comes to adopting a low-code platform to drive their digital transformation strategy. IT centric low-code development platforms Designed for skilled developers to make their jobs easier and faster. They were a big hit once developers figured them out. They have built-in development, testing, production, licensing, and data governance. The tools are built on well-known development principles and can be used to construct various apps. But this is also their downfall, at least from a business point of view.  Because line-of-business stakeholders are unfamiliar with the tools, their involvement in the development process is generally limited to translating requirements. Resulting in a single-threaded delivery model where developers need to comprehend business requirements, generate a technical specification, and then go through blueprinting budgeting development user acceptance testing (UAT), go live, and then modify requests resuming the process. Businesses also struggled to grasp what was going on "behind the scenes," leaving them unable to assess how the application "behaved" in connection to their original business requirements. This is because they can't see what they're dealing with and in the end this slows down the development cycle. In this category I identified the following low-code platforms: Pega Agilepoint Unqork Caspio Aura Quantic Low-code development platforms for citizen developers Low-code platforms for citizen developers can be used to produce low to mid-complexity applications for 12-24 users inside an organization to achieve a certain goal, ideal for start-ups. Anyone who understands the business subject matter can build and change it fast. However, because these solutions are designed for small workgroups, they often lacked the scalability and interoperability required for big user communities, complicated technological environments, and enterprise deployments. They either hit severe limits or required extensive technical intervention from a range of technical disciplines to try and extend what wasn't inherent to the tool itself. Low-code platforms posed new issues for enterprises and IT professionals entrusted with assuring governance over application deployment and business utility. Many strengths we see in the IT centric low-code platforms, such as numerous staging environments, access rights, data for technical and business audits, important security features, license control, and on-premises deployment choices are frequently absent from their core set of functionalities. It’s no surprise that many IT professionals are still hesitant of implementing these toolsets. In this category I identified the following low-code platforms: PowerApps Betty Blocks Creatio Kissflow 3. Low-code development platforms for collaboration Low-code platforms developed for collaboration combine the best of both types of platforms listed above, allowing enterprises to build simple to complex apps that expand from dozens to thousands of users and transactions. They include all the controls and functionalities required for enterprise governance while also fostering a more collaborative environment in which subject matter experts can contribute to the development of a software application, understand what is being built as it is being built, and contribute in a way that is intuitive to their specific expertise. With low-code platforms built for collaboration, it is possible to have the business stakeholder work on aspects of the build that align with their expertise (automation flows, data models, UI design), while leaving the technical aspects (integrations, access control, staging environments, technical audits) to the IT subject matter experts. This eliminates business and IT silos and enable faster time to value for both parties. Enterprises can have technical and business teams working together on a same platform for a common goal. It's business-grade, has built-in governance, is intuitive for all users, and can scale quickly from departmental to corporate apps and it meets the needs of today's time-pressed, multi-faceted, ever-growing businesses. In this category I identified the following low-code platforms: Aurachain Mendix In 2022, digital transformation will reach new heights, but are we about to make the same software failure mistakes all over again? The past two years have been a wake-up call for firms without a clear digital transformation strategy.  The epidemic has emphasized the necessity for businesses to produce digital apps swiftly and easily adaptive to shifting needs. Businesses needed to change quickly and were looking for more cost-effective and agile solutions, but they must be careful when choosing their low-code approach. As Jonathan Wiener writes in TechRegister in his article ( SEE: Are we about to make the same software failure mistakes all over again?) “The risk ahead lies in the fact that many of the tools being used in low-code development environments when they divide rather than unite the various specialists in the process. They create ‘fiefdoms’ between tech and business rather than bringing the two sides together into one ‘development conversation.’ On the one hand we hear about developers wanting to retain control of their knowledge (and rightly so in many ways), while trends such as the citizen developer suggest it is OK for non-techies to build their own systems in isolation. It is OK at a basic workflow level, but not when you’re addressing mission-critical problems and enterprise application use. ” Collaboration should extend beyond teams working together to create a new digital app. It should exist at all stages of the development cycle, from process design to documentation, API design, publication, and app performance analysis. It is a collaborative effort between all essential parties, aided by technology. When work is 'democratized' among all relevant business and technical subject matter experts, a team can build together within the platform rather than working in isolation on its composite elements. To do so, a platform that is both user-friendly and enterprise-grade – with built-in governance, mission-critical change support, and cloud-native scalability – is required. The good news is that these types of platforms are now available on the LCP Market in the form of collaboration platforms - they are business-grade, have built-in governance, are intuitive for all users, and can scale quickly from departmental to corporate apps, and they meet the needs of today's time-pressed, multi-faceted, ever-growing businesses.

3 Types of Low-Code Development Platform That Every CIO Should Know About

Building a product is often the most challenging part of building a startup. That’s why lots of founders want to rid themselves of it by outsourcing this to other companies. And there’s nothing wrong with that if you’ve got the time and the money. Dev shops are great in terms of experience having built hundreds of similar or even identical projects from scratch, they know what you’re coming for. It also means that Is there this kind of technology? The short answer is no. The better answer is we’re building it right this second. Let’s first dive into the available options there are. This is for complicated projects when you’ve really got something robust going on and can’t find other sustainable solutions in the long run. But if your thing pretty much copies another idea (and there’s nothing wrong with that, the best ideas are stolen) then it’s not necessary at all. So, if you’re pitching a “next Uber/Instagram/Airbnb/…” or anything else you’re going to replicate to your investors, don’t ask for 250$k for development, Believe it or not, developers can write less code and get the same results. Why is your dev shop not interested in that? You guessed it, they can’t charge you as much. It’s as simple as that. If you’re a tech founder it’s the perfect one for you, though. Learn how a low-code platform works, or two. Low-code platforms: , , , No-code is the easiest and the fastest alternative to them all. Or, at least, that’s what the belief is. Sure, you can use drag-and-drop solutions for your early versions/prototypes/MVP but if you need something a little more sophisticated then the learning curve is fairly steep. Have you noticed that there are actually not so many Webflow developers? I mean, good Webflow developers. While no-code is sustainable for the idea validation stage and maybe a little bit further along, it won’t carry you through the rapid growth stage. And you’ll eventually have to scratch all your beautiful work and go to custom code. No-code platforms: , , , If you’re selling something online, there’s Shopify, Gumroad, WooCommerce, and even Wix. All you need is a few hours away from Netflix and you have an online business. And these are great at what they do. They are limited but you get enough features to get you going, you’re supported, safe, and pretty much self-explanatory. Platforms: , , , Or white label, if you will. Building a taxi app? There’s probably something on the market, buy it, stick your brand name on it and you’re good to go. Will it give you the freedom to grow and add innovative ideas? Probably not. Will it still be fine if your competitive advantage is exceptional service or a unique business model? Yes. with the right technology at hand, they’d be able to reuse parts or even projects almost to the “T” for other projects. 1. Custom code you can do it way cheaper. 2. Low-code It’ll make you way more efficient and give you all the control over your project. Caspio Retool Creatio OutSystems 3. No-code Because you’ve got to learn a lot. A LOT. And then once you’ve learned it all, you hit the ceiling. XPODA Bubble Lansa Airtable 4. Platforms You just need to play by their rules. Shopify Gumroad WooCommerce Wix 5. Out of the box Out of the box: , Twilio Cyclr 6. Mars Choosing among the above options might not be an easy task. Especially if you are a first-time startup maker. But fear not! There is a tool that combines the benefits of all the previous items – Mars. Mars is an open-source platform for making web and mobile apps. It gives you flexibility on demand. You get access to the custom code only when you want to implement a specific feature. As for the regular functionalities, such as login page, payments, cart, dropdown menu, footer, photo galleries, and profile page, you can plug them into your startup with little-to-zero coding knowledge. This makes Mars the perfect tool for making MVP: you are building fast most of the time, and you go to custom code only to make unique changes. You’re saving time but you’re not trading anything away for that. However, there is a disadvantage to using the platform. It is a new technology and it lacks good documentation. The learning curve may be a little steep, especially for a complete beginner. But once you get used to Mars, you will be able to build complex applications such as Airbnb, UBER, and Instagram amazingly easily. The tool: . Mars

Low-code vs No-code: Selecting the Best Stack For Your Startup

The world of cryptocurrency should be doing everything it can to attract institutional investors. With $130 trillion of assets under management worldwide, institutional investors could have a huge positive impact if they moved even a tiny fraction of those funds into crypto, whose market cap remains under $300 billion. — Yet diving into the world of crypto can be incredibly daunting. On top of understanding the workings of the underlying technology, newcomers wishing to trade need to adapt to an incredibly volatile market and learn the ropes across a handful of exchanges. Many struggle to reconcile the fragmentation of these platforms there’s no one-stop shop, meaning that traders must interact with a plethora of exchanges to acquire the crypto assets they want. , it’s clear that investors . We’ve seen institutional players engaging — managing portfolios through Excel spreadsheets, writing Python scripts to execute trades, and using multiple web interfaces. There are, of course, a couple of exceptions to this rule, but for the vast majority, this rudimentary setup is fast becoming the norm. On the institutional front have been struggling in practices almost unheard of at that level in traditional markets through a comprehensive solution for asset management. Institutions are able to access a fully-fledged platform worthy of traditional markets. Complete with a suite of tools such as OEMS, PMS and RMS, as well as a number of sophisticated trading algorithms, the Caspian solution integrates with the backend of numerous exchanges so that users can access them from a single intuitive interface. Caspian aims to set the bar somewhat higher Tools like Caspian should be of great interest, not only to these entities, but to crypto evangelists and speculators at large — the long-term viability of the space is dependent on increasing investments, but many funds will not enter until more streamlined trading platforms can be offered. The introduction of products such as Caspian will therefore bridge an important gap between incumbent institutions, and the rapidly-evolving crypto space. Institutional players will be seminal in pushing the cryptocurrency market cap to the next level. Supporting as many exchanges as possible has been our main focus for a number of reasons — the first being arbitrage: there’s a lot of money to be made in leveraging prices discrepancies across exchanges. Another motivation for this is a lack of liquidity on a single exchange when executing high-volume orders. Tying the different platforms together in the same interface makes it much easier to fill orders, by drawing on not one, but several pools. This has the added benefit of spreading risk — many exchanges are unregulated, so Caspian mitigates counterparty risk. With decades of experience in banking, creating institutional-grade trading software and operating hedge funds, the Caspian team brings together a wealth of talent from around the world. It currently has over 40 engineers working on understanding and interacting with the various different APIs offered by exchanges. It’s an arduous task, due to the lack of widely-accepted standards in the industry, as well as all the different technology and language used for their API connections, but it’s also a necessary one to deliver the sophisticated platform that Caspian aims to roll out, and to bring new investors into crypto. About The Author is CTO & Co-founder of Caspian. He has served as Managing Director at Tora for the past 12 years. Prior to that Gerrit managed the development of high volume trading applications and analytical tools for various hedge funds and bulge bracket investment banks. Gerrit holds a B.S. in Computer Science from Stanford University Gerrit Van Wingerden About Caspian is a full-stack cryptoasset management platform tying together the biggest crypto exchanges in a single interface, so as to facilitate investments in crypto instruments for newcomers and veterans alike.

Edison's Conquest of Mars by Garrett Putman Serviss is part of the HackerNoon Books Series. You can jump to any chapter in this book here . Chapter XVIII Edison's Conquest of Mars Chapter XVIII When at length we once more saw our native planet, with its well-remembered features of land and sea, rolling beneath our eyes, the feeling of joy that came over us transcended all powers of expression. In order that all the nations which had united in sending out the expedition should have visual evidence of its triumphant return, it was decided to make the entire circuit of the earth before seeking our starting point and disembarking. Brief accounts in all known languages, telling the story of what we had done were accordingly prepared, and then we dropped down through the air until again we saw the well-loved blue dome over our heads, and found ourselves suspended directly above the white-topped cone of Fujiyama, the sacred mountain of Japan. Shifting our place toward the northeast, we hung above the city of Tokio and dropped down into the crowds that had assembled to watch us, the prepared accounts of our journey, which, the moment they had been read and comprehended, led to such an outburst of rejoicing as it would be quite impossible to describe. One of the ships containing the Japanese members of the expedition dropped to the ground, and we left them in the midst of their rejoicing countrymen. Before we started—and we remained but a short time suspended above the Japanese capital—millions had assembled to greet us with their cheers. We now repeated what we had done during our first examination of the surface of Mars. We simply remained suspended in the atmosphere, allowing the earth to turn beneath us. As Japan receded in the distance we found China beginning to appear. Shifting our position a little toward the south we again came to rest over the city of Pekin, where once more we parted with some of our companions, and where the outburst of universal rejoicing was repeated. From Asia, crossing the Caspian Sea, we passed over Russia, visiting in turn Moscow and St. Petersburg. Still the great globe rolled steadily beneath, and still we kept the sun with us. Now Germany appeared, and now Italy, and then France, and England, as we shifted our position, first North then South, in order to give all the world the opportunity to see that its warriors had returned victorious from their far conquest. And in each country as it passed beneath our feet, we left some of the comrades who had shared our perils and our adventures. At length the Atlantic had rolled away under us, and we saw the spires of the new New York. The news of our coming had been flashed ahead from Europe, and our countrymen were prepared to welcome us. We had originally started, it will be remembered, at midnight, and now again as we approached the new capital of the world the curtain of night was just beginning to be drawn over it. But our signal lights were ablaze, and through these they were aware of our approach. Again the air was filled with bursting rockets and shaken with the roar of cannon, and with volleying cheers, poured from millions of throats, as we came to rest directly above the city. Three days after the landing of the fleet, and when the first enthusiasm of our reception had a little passed, I received a beautifully engraved card inviting me to be present in Trinity Church at the wedding of Aina and Sidney Phillips. When I arrived at the church, which had been splendidly decorated, I found there Mr. Edison, Lord Kelvin, and all the other members of the crew of the flagship, and, considerably to my surprise, Colonel Smith, appropriately attired, and with a grace for the possession of which I had not given him credit, gave away the beautiful bride. But Alonzo Jefferson Smith was a man and a soldier, every inch of him. "I asked her for myself," he whispered to me after the ceremony, swallowing a great lump in his throat, "but she has had the desire of her heart. I am going back to the plains. I can get a command again, and I still know how to fight." And thus was united, for all future time, the first stem of the Aryan race, which had been long lost, but not destroyed, with the latest offspring of that great family, and the link which had served to bring them together was the far-away planet of Mars.

THE PHYSICAL NATURE OF THE STARS

STAR CLUSTERS AND NEBULÆ

THE STARRY HEAVENS

Star-land: Being Talks With Young People About the Wonders of the Heavens by Robert S. Ball is part of the HackerNoon Books Series. You can jump to any chapter in this book here . CONCLUDING CHAPTER CONCLUDING CHAPTER. HOW TO NAME THE STARS Every one who wishes to learn something about astronomy should make a determined effort to become acquainted with the principal constellations, and to find out the names of the brighter and more interesting stars. I have therefore added to Star-land this little chapter, in which I have tried to make the study of the stars so simple that, by taking advantage of a few clear nights, there ought to be no difficulty in obtaining a knowledge of a few constellations. The first step is to become familiar with the Great Bear, or Ursa Major, as astronomers more generally call the group. We begin with this, because after it has been once recognized, then you will find it quite easy to make out the other constellations and stars. It may save you some trouble if you can get some one to point out to you the Great Bear; but even without such aid, I think you will be able to make out the seven bright stars which form this remarkable group, from the figure here given ( ). Of course, the position of this constellation, as of every other in the heavens, changes with the hour of the night, and changes with the seasons of the year. About April the constellation at 11 o’clock at night is high over your head. In September at the same hour, the Great Bear is low down in the north. It is to be seen in the west382 in July, and at Christmas it lies in the east at convenient hours in the evening for observation. One of the advantages of using the Great Bear as the foundation of our study of the stars arises from the fact that to an observer in the British Islands or in similar latitudes this group never sets. Whenever the sky is clear after nightfall, the Great Bear is to be seen somewhere, while the brightness of its component stars makes it a conspicuous object. Indeed, there is only one constellation383 in the sky, namely, that of Orion, which is a more brilliant group than the Great Bear. We shall tell you about Orion presently, but it does not suit to begin with, because it can only be seen in winter, and is then placed very low down in the heavens. Fig. 92 Fig. 92.—The Great Bear and the Pole Star. Your next lesson will be to utilize the Great Bear for the purpose of pointing out the Pole Star. Look at the two stars marked α and β. They are called the “Pointers,” because if you follow the direction they indicate along the dotted line in the figure, they will conduct your glance to the Pole. This is the most important star in the heavens to astronomers, because it happens to mark very nearly the position of the Pole on the sky. You will easily note the peculiarity of the Pole Star if you will look at it two or three times in the course of the night. It will appear to remain in the same place in the sky, while the other stars change their places from hour to hour. It is very fortunate that we have a star like this in the northern heavens; the astronomers in Australia or New Zealand can see no bright star lying near the Southern Pole which will answer the purposes that the Pole Star does so conveniently for us in the north. The Pole Star belongs to a constellation which we call the Little Bear; two other conspicuous members of this group are the two “Guards”; you will see how they are situated from , . They lie nearly midway between the Pole Star and the last of the three stars which form the Great Bear’s Tail. The same figure will also introduce us to another beautiful constellation, namely, Cassiopeia. You will never find384 any difficulty in identifying the figure that marks this group if you will notice that the Pole lies midway between it and the Great Bear. Fig. 82 p. 322 Fig. 93.—The Great Square of Pegasus. Cassiopeia is also one of the constellations that never set to British observers; but now we have to speak of groups which do set, and which, therefore, can only be observed when the proper season comes round. The first of these is “the Great Square of Pegasus”; you cannot see this group conveniently in the spring or summer, but during the autumn and winter it is well placed after nightfall. There are four conspicuous stars forming the corners of the square, and then three others marked α, γ, and β ( ), which form a sort of handle to the square. In fact, if you once recognize this group, you will perhaps see in it a resemblance to a great saucepan with a somewhat bent handle, and then you385 will be acquainted with a large tract of Star-land near the Square of Pegasus. From the figure you will see that a line imagined to be drawn from the Pole Star over the end of Cassiopeia, and then produced as far again, will just lead to the Great Square. I have also marked on this figure two objects that are of great telescopic interest; one of them is the Nebula in Andromeda, of which we had an account in the last lecture. You see it lies halfway between the corner α of the square and the group of Cassiopeia. Another interesting object is the star marked γ Andromedæ. The telescope shows it to consist of a pair of stars, the colors of which are beautifully contrasted. Fig. 93 At the end of this handle to the Great Square of Pegasus is the star α, in the constellation of Perseus. It lies between two other stars γ and δ. We refer to , in which these stars are shown. We there employed the figure to indicate the position of Algol, the remarkable variable star. Your map will also point out some other important stellar features. If we curve round the three marked γ, α, and δ of Perseus, the eye is conducted to Capella, a gem of the first magnitude in the constellation of Auriga. Close to Capella is a long triangle, the corners of which are the “Hœdi,” the three kids—which Capella is supposed to nurture. Fig. 84 If we carry a curve through γ, α, δ, of Perseus, and now bend it in the opposite way, the eye is led through ε and ζ in the same constellation, and then on to the Pleiades, of which we have already spoken. Fig. 94.—Orion and Sirius. Perseus lies in one of the richest parts of the heavens.387 The Milky Way stretches across the group, and the sky is strewn with stars beyond number. Even an opera-glass directed to this teeming constellation cannot fail to afford the observer a delightful glimpse of celestial scenery. We may, however, specially remind the beginner that the objects on this map are not always to be seen, and as an illustration of the way in which the situation and the visibility of the constellations are affected by the time of year, I shall take the case of the Pleiades and follow them through a season. Let us suppose that we make a search for this group at 11 P.M. every night. On the 1st of January, the Pleiades will be found high up in the sky in the southwest. On the 1st of March, they will be setting in the west at the same hour. On the 1st of May, the Pleiades are not visible, neither are they on the 1st of July. On the 1st of September, they will be seen low down in the east. On the 1st of November, they will be high in the heavens in the southeast. On the ensuing 1st of January, the Pleiades will be found back in the same place which they occupied on the same date in the preceding year, and so on throughout the cycle. Of course, you will not suppose that their changes are due to actual motions in the group of stars themselves. They are merely apparent, and are to be explained by the motion of the earth round its axis, and the revolution around the sun. Next we are to become acquainted with the glory of our winter skies, the constellation of Orion, . I dare say many of my readers are already familiar with388 the well-known twin stars which form the belt of Orion, but if not, they will be able to recognize it by the help of the groups already learned. Imagine a line drawn from the Pole Star through Capella, and then produced as much further again, and we shall be conducted into the precincts of Orion. This group lies on the equator, and, consequently, it is equally familiar to southern astronomers and to those of the north. It can be best seen by those who observe it from or near the equator. Fig. 94 The brightest star in Orion is known either as α Orionis or as Betelgeuze, by which name it is represented in the figure. This star is of the first magnitude, and so is Rigel on the opposite side of the belt. The three stars of the belt and the two others, γ and κ, at which they point above and below, are of second magnitude. The owner of a telescope finds especial attractions in this constellation. Notably among the subjects which will interest him is the Great Nebula, the position of which is indicated in our figure. Under the middle of the belt are a few stars, around which is a hazy light that is perceptible with the smallest telescopic aid. Viewed by instruments of adequate proportions, these have developed into a marvellous nebula of glowing gas, attaining to dimensions so vast that no one has yet ever attempted to estimate them. The vicinity of Orion is also enriched with some of the most interesting stellar objects. Follow the line of the belt upwards to the right, and your eye is conducted to a ruddy first magnitude star named Aldebaran, in the constellation of the Bull. This is a pleasing object,389 which the beginner will sometimes be apt to confuse with the planet Mars, to which, under certain circumstances, it certainly bears a resemblance. Another very pleasing little group, known as the Hyades, will be found near Aldebaran. If the line of the belt of Orion be carried down to the left, it will be found to point to Sirius, or the Dog Star. You will find it an interesting occupation to make for yourself maps of small parts of the heavens. First copy out the chief stars in their proper places from the star atlas, and then fill in the smaller stars with your own observations. Try first on some limited region of the heavens; take the figure of Cassiopeia, for instance, or the Square of Pegasus, and see if you can produce a fair representation of those groups by marking in the stars that your instrument will show you; or take the Pleiades and make a tracing of the principal stars of the group from the sketch that we have given ( ), then take an opera-glass and fill in as carefully as you can all that it will show. I can assure you that you will find a little definite work of this kind full of interest and instruction. Fig. 89 But I hope you will desire to advance further in the study of the heavens. It is to be remembered that with even the most moderate instruments there is much to be done. Many comets have been detected, and many planets have been discovered, by the use of telescopes so small that they could be easily carried out from the house for the evening’s work and brought back again after the observations were over. It remains for me to add a few words which will help390 you in finding the planets. It is, of course, impossible to represent such objects as Jupiter, Saturn, Venus, Mars, and Mercury on maps of the heavens, because these bodies are constantly moving about, and if their places were right to-day they would be wrong to-morrow. The almanac will be necessary for you here. You must find out by its help what planets are visible and in what part of the sky they are placed. Then you will have to compare your maps with the heavens, and when you find a bright star-like body that is not shown on your maps you may conclude at once that it is the planet. Although these objects are so star-like to the unaided eye, yet the resemblance is at once dispelled when we use a telescope. The star is only a bright point of light and white, the planet shows a visible shape. This is, at least, the case with the five planets I have named; for there are others, such as Uranus and Neptune, which are too far to be much more than star-like points in ordinary telescopes. The minor planets would not interest you. I hope that the reading of Star-land will, at all events, induce you to make a beginning of the study of the heavens, if you have not already done so. If you have the advantage of a telescope, so much the better; but, if this is impossible, make the best use of your own eyes. Do not put it off or wait till you get some one to teach you. If it be clear this very night, go out and find the Great Bear and the Pole Star, and as many of the other constellations as you can, and at once commence your career as an astronomer.

THE FRENCHMAN'S NEW SCHEME After the disappearance of Mt. Everest, Cosmo Versál made a careful measurement of the depth of water on the peak, which he found to be forty feet, and then decided to cruise eastward with the Ark, sailing slowly, and returning after a month to see whether by that time there would be any indications of the reappearance of land. No part of his extraordinary theory of the deluge was more revolutionary, or scientifically incredible, than this idea that the continents would gradually emerge again, owing to internal stresses set up in the crust of the earth. This, he anticipated, would be caused by the tremendous pressure of the water, which must be ten or twelve miles deep over the greatest depressions of the old ocean-bottoms. He expected that geological movements would attend the intrusion of the water into subterranean cavities and into the heated magma under volcanic regions. He often debated the question with the savants aboard the Ark, and, despite their incredulity, he persisted in his opinion. He could not be shaken, either, in his belief that the first land to emerge would be the Himalayas, the Pamirs, and the plateau of Tibet. "We may have to wait some years before any considerable area is exposed," he admitted, "but it must not be forgotten that what land does first appear above the water will lie at the existing sea-level, and will have an oceanic climate, suitable for the rapid development of plants. "We have aboard all things needed for quick cultivation, and in one season we could begin to raise crops." "But at first," said Professor Jeremiah Moses, "only mountain tops will emerge, and how can you expect to cultivate them?" "There is every probability," replied Cosmo, "that even the rocks of a mountain will be sufficiently friable after their submergence to be readily reduced to the state of soil, especially with the aid of the chemical agents which I have brought along, and I have no fear that I could not, in a few weeks, make even the top of Everest fertile. "I anticipate, in fact, that it will be on that very summit that we shall begin the re-establishment of the race. Then, as the plateaus below come to the surface, we can gradually descend and enlarge the field of our operations." "Suppose Everest should be turned into a volcano?" "That cannot happen," said Cosmo. "A volcano is built up by the extrusion of lava and cinders from below, and these cannot break forth at the top of a mountain already formed, especially when that mountain has no volcanic chimney and no crater, and Everest had neither." "If the lowering of the flood that caused our stranding on a mountain top in Sicily was due to the absorption of water into the interior of the crust, why may not that occur again, and thus bring the Himalayas into view, without any rising on their part?" demanded Professor Moses. "I think," said Cosmo, "that all the water that could enter the crust has already done so, during the time that the depression of level which so surprised us was going on. Now we must wait for geologic changes, resulting from the gradual yielding of the internal mass to the new forces brought to bear upon it. "As the whole earth has gained in weight by the condensation of the nebula upon it, its plastic crust will proportionally gain in girth by internal expansion, which will finally bring all the old continents to the surface, but Asia first of all." Whether Cosmo Versál's hypotheses were right or wrong, he always had a reply to any objection, and the prestige which he had gained by his disastrously correct theory about the watery nebula gave him an advantage so enormous that nobody felt enough confidence in himself to stand long against anything that he might advance. Accordingly, everybody in the Ark found himself looking forward to the re-emergence of Mount Everest almost as confidently as did their leader, Cosmo Versál. They began their waiting voyage by sailing across the plateau of Tibet and the lofty chain of the Yung-ling Mountains out over China. The interest of all aboard was excited to the highest degree when they found themselves sailing over the mighty domains of the Chinese President-Emperor, who had developed an enormous power, making him the ruler of the whole eastern world. He, with his half-billion or more of subjects, now reposed at the bottom of an ocean varying from three to five or six miles in depth. Deep beneath the Ark lay the broad and once populous valleys of the Yangtse-Kiang and the Hoang-Ho, the "Scourge of China." Finally they swung round northward and re-entered the region of Tibet, seeking once more the drowned crown of the world. In the meantime Cosmo had had the theatrical exhibitions and the concerts resumed in the evenings, and sometimes there was music, and even dancing on the long promenades, open to the outer air. Let not that be a matter of surprise or blame, for the spirit of joy in life is unconquerable, as it should be if life is worth while. So it happened that, not infrequently, and not with any blameworthy intention, or in any spirit of heartless forgetfulness, this remarkable company of world-wanderers drifted, in the moonlight, above the universal watery grave of the drowned millions, with the harmonies of stringed instruments stealing out upon the rippling waves, and the soft sound of swiftly shuffling feet tripping over the smooth decks. Costaké Theriade and Sir Wilfrid Athelstone resumed their stormy efforts to talk each other down, but now even Cosmo was seldom a listener, except when he had to interfere to keep the peace. King Richard and Amos Blank, however, usually heard them out, but it was evident from their expressions that they enjoyed the prospective fisticuffs rather more than the exposition of strange scientific doctrines. Perhaps the happiest man aboard was Captain Arms. At last he could make as many and as certain observations as he chose, and he studied the charts of Asia until he declared that now he knew the latitude and longitude of the mountains better than he did those of the seaports of the old oceans. He had not the least difficulty in finding the location of Mount Everest again, and when he announced that they were floating over it, Cosmo immediately prepared to make another measurement of the depth of water on the peak. The result was hardly gratifying. He found that it had diminished but four inches. He said to Captain Arms: "The range is rising, but less rapidly than I hoped. Even if the present rate should be doubled it would require five years for the emergence of the highest point. Instead of remaining in this part of the world we shall have an abundance of time to voyage round the earth, going leisurely, and when we get back again perhaps there will be enough land visible to give us a good start." "Mr. Versál," said the captain, "you remember that you promised me that I should drop my anchor on the head of Mount Everest if I worked a traverse across Beluchistan." "Certainly I remember it; and also that you were not much disposed to undertake the task. However, you did it well, and I suppose that now you want me to fulfill the bargain?" "Exactly," replied the captain. "I'd just like to get a mud-hook in the top-knot of the earth. I reckon that that'll lay over all the sea yarns ever spun." "Very well," returned Cosmo. "Try it, if you've got cable enough." "Enough and to spare," cried the captain, "and I'll have the Gaurisankar, as the Frenchman calls it, hooked in a jiffy." This was an operation which called everybody to the rails to watch it. Hundreds of eyes tried to follow the anchor as it descended perpendicularly upon the mountain-top, nearly forty feet beneath. Through the clear water they could dimly see the dark outline of the summit below, and they gazed at it with wonder, and a sort of terror. Somehow they felt that never before had they fully appreciated the awful depths over which they had been floating. The anchor steadily dropped until it rested on the rock. It got a hold finally, and in a few minutes the great vessel was swinging slowly round, held by a cable whose grasp was upon the top of the world! When the sensation had been sufficiently enjoyed the anchor was tripped, and the nose of the Ark was turned northwestward. Cosmo Versál announced his intention to circumnavigate the drowned globe. The news of what they were about to do was both welcome and saddening to the inmates of the vessel. They wished to pass once more over the lands where they had first seen the light, and at the same time they dreaded the memories that such a voyage would inevitably bring back with overwhelming force. But, at any rate, it would be better than drifting for years over Tibet and China. While everybody else was discussing the prospects of the new voyage, and wondering how long it would last, Yves de Beauxchamps was concentrating all his attention upon a new project which had sprung up in his active mind as soon as Cosmo's intention was announced. He took Cosmo aside and said to him: "M. Versál, the dearest memory that I have treasured in my heart is that of the last sight of my drowned home, my beautiful dead Paris. It may be that the home-loving instincts of my race arouse in me a melancholy pleasure over such a sight which would not be shared by you, of a different blood; but if, perchance, you do share my feelings on this subject I believe that I can promise you a similar visit to the great metropolis where your life began, and where you executed those labors whose result has been to preserve a remnant of humanity to repeople the earth." Cosmo Versál's quick intelligence instantly comprehended the Frenchman's design, but it startled him, and apparently insuperable difficulties at once occurred to his mind. "M. De Beauxchamps," he responded, grasping his friend warmly by the hand, "I thank you from the bottom of my heart for your amiable intention, and I assure you that nothing could afford me greater satisfaction than to see once more that mighty city, even though it can now be but an awful ruin, tenanted by no life except the terrible creatures of the deep. But, while I foresee what your plan must be, I can hardly conceive that its execution could be possible. You are thinking, of course, of constructing a diving apparatus capable of penetrating to a depth of nearly six miles in the sea. Setting aside the question whether we could find in the stores of the Ark the materials that would be needed, it appears to me most improbable that we could make the apparatus of sufficient strength to withstand the pressure, and could then cause it to sink to so great a depth, and afterward bring it safely to the surface." The Frenchman smiled. "M. Versál," he replied, "I have taken the liberty to look over the stock of materials which you have so wisely prepared for possible repairs to the Ark and for use after the Ark lands, and I know that among them I can find all that I shall need. You yourself know how completely you are provided with engineering tools and machines of all kinds. You have even an electric foundry aboard. With the aid of your mechanical genius, and the skill of your assistants, together with that of my own men, who are accustomed to work of this kind, I have not the faintest doubt that I can design and construct a diving-bell, large enough to contain a half-dozen persons, and perfectly capable of penetrating to any depth. Of course I cannot make it of levium, but you have a sufficient supply of herculeum steel, the strength of which is so immense that the walls of the bell can be made to remit the pressure even at a depth of six miles. From my previous experiments I am confident that there will be no difficulty in sinking and afterward raising this apparatus. It is only necessary that the mean specific gravity of the bell shall be greater than that of the water at a given depth, and you know that as far back as the end of the nineteenth century your own countrymen sent down sounding apparatus more than six miles in the Pacific Ocean, near the island of Guam." "But the air inside the bell—" Cosmo began. "Excuse me," interrupted De Beauxchamps, "but that air need be under no greater pressure than at the surface. I shall know how to provide for that. Remember the Jules Verne. Simply give me carte blanche in this matter, let me have the materials to work with, afford me the advantage of your advice and assistance whenever I shall need them, and I promise you that by the time we have arrived over the site of New York we shall be prepared for the descent." Cosmo was deeply impressed by the Frenchman's enthusiastic self-confidence. He had a great admiration for the constructor of the Jules Verne, and, besides, the proposed adventure was exactly after his own heart. After meditating a while, he said heartily: "Well, M. De Beauxchamps, I give my consent. Everything you wish shall be at your disposal, and you can begin as soon as you choose. Only, let the thing be kept a secret between us and the workmen who are employed. If it should turn out a failure it would not do that the people in the Ark should be aware of it. I can give you a working room on one of the lower decks, where there will be no interference with your proceedings, and no knowledge of what you are about can leak out." "That is exactly what I should wish," returned De Beauxchamps, smiling with delight, "and I renew my promise that you shall not be disappointed." So, without a suspicion of what was going on entering the minds of any person in the great company outside the small company of men who were actually employed in the work, the construction of De Beauxchamps's great diving-bell was begun, and pushed with all possible speed, consistent with the proper execution of the work. In the meantime the Ark continued its course toward the west. They ran slowly, for there was no hurry, and the Ark had now become to its inhabitants as a house and a home—their only foothold on the whole round earth, and that but a little floating island of buoyant metal. They crossed the Pamirs and the Hindu-Kush, the place where the Caspian Sea had been swallowed up in the universal ocean, and ran over Ararat, which three months before had put them into such fearful danger, but whose loftiest summit now lay twelve thousand feet beneath their keel. At length, after many excursions toward the north and toward the south, in the halcyon weather that had seldom failed since the withdrawal of the nebula, they arrived at the place (or above it) which had stood during centuries for a noon-mark on the globe. It was midday when Captain Arms, having made his observations, said to Cosmo and the others on the bridge: "Noon at Greenwich, and noon on the Ark. Latitude, fifty-one degrees thirty minutes. That brings you as nearly plumb over the place as you'd be likely to hit it. Right down there lies the old observatory that set the chronometers of the world, and kept the clocks and watches up to their work." King Richard turned aside upon hearing the captain's words. They brought a too vivid picture of the great capital, six miles under their feet, and a too poignant recollection of the disastrous escape of the royal family from overwhelmed London seven months before. As reckoned by the almanac, it was the 15th of September, more than sixteen months since Cosmo had sent out his first warning to the public, when the Ark crossed the meridian of seventy-four degrees west, in about forty-one degrees north latitude, and the adventurers knew that New York was once more beneath them. There was great emotion among both passengers and crew, for the majority of them had either dwelt in New York or been in some way associated with its enterprises and its people, and, vain as must be the hope of seeing any relic of the buried metropolis, every eye was on the alert. They looked off across the boundless sea in every direction, interrogating every suspicious object on the far horizon, and even peering curiously into the blue abyss, as if something might suddenly appear there which would speak to them like a voice from the past. But they saw only shafts of sunlight running into bottomless depths, and occasionally some oceanic creature floating lazily far below. The color of the sea was wonderful. It had attracted their attention after the submergence of Mount Everest, but at that time it had not yet assumed its full splendor. At first, no doubt, there was considerable dissolved matter in the water, but gradually this settled, and the sea became bluer and bluer—not the deep indigo of the old ocean, but a much lighter and more brilliant hue—and here, over the site of New York, the waters were of a bright, luminous sapphire, that dazzled the eye. Cosmo declared that the change of the sea-color was undoubtedly due to some quality in the nebula from whose condensation the water had been produced, but neither his own analyses, nor those of the chemists aboard the Ark, were able to detect the subtle element to whose presence the peculiar tint was due. But whatever it may have been, it imparted to the ocean an ethereal, imponderous look, which was sometimes startling. There were moments when they almost expected to see it expand back into the nebulous form and fly away.
