CHAPTER LII. here CHAPTER LII. “PACK CLOUDS AWAY.” “For joy or grief, for hope or fear, For all hereafter, as for here, In peace or strife, in storm or shine.” Anon. Edith went about on tip-toe, and checked Sholto in all loud speaking that next morning, as if any sudden noise would interrupt the conference that was taking place in the drawing-room. Two o’clock came; and they still sate there with closed doors. Then there was a man’s footstep running down stairs; and Edith peeped out of the drawing-room. “Well, Henry?” said she, with a look of interrogation. “Well!” said he, rather shortly. “Come in to lunch!” “No, thank you, I can’t. I’ve lost too much time here already.” “Then it’s not all settled?” said Edith, despondingly. “No! not at all. It never will be settled, if the ‘it’ is what I conjecture you mean. That will never be, Edith, so give up thinking about it.” “But it would be so nice for us all,” pleaded Edith. “I should always feel comfortable about the children, if I had Margaret settled down near to me. As it is, I am always afraid of her going off to Cadiz.” “I will try, when I marry, to look out for a young lady who has a knowledge of the management of children. That is all I can do. Miss Hale will not have me. And I shall not ask her.” “Then what have you been talking about?” “A thousand things you would not understand: Investments, and leases, and value of land.” “Oh, go away if that’s all. You and she will be unbearably stupid, if you’ve been talking all this time about such weary things.” “Very well. I’m coming again to-morrow, and bringing Mr. Thornton with me, to have some more talk with Miss Hale.” “Mr. Thornton! What has he to do with it?” “He is Miss Hale’s tenant,” said Mr. Lennox, turning away. “And he wishes to give up his lease.” “Oh! very well. I can’t understand details, so don’t give them me.” “The only detail I want you to understand is, to let us have the back drawing-room undisturbed, as it was to-day. In general, the children and servants are so in and out, that I can never get any business satisfactorily explained; and the arrangements we have to make to-morrow are of importance.” No one ever knew why Mr. Lennox did not keep to his appointment on the following day. Mr. Thornton came true to his time; and after keeping him waiting for nearly an hour, Margaret came in looking very white and anxious. She began hurriedly: “I am so sorry Mr. Lennox is not here,—he could have done it so much better than I can. He is my adviser in this”—— “I am sorry that I came, if it troubles you. Shall I go to Mr. Lennox’s chambers and try and find him?” “No, thank you. I wanted to tell you, how grieved I was to find that I am to lose you as a tenant. But, Mr. Lennox says, things are sure to brighten”—— “Mr. Lennox knows little about it,” said Mr. Thornton quietly. “Happy and fortunate in all a man cares for, he does not understand what it is to find oneself no longer young—yet thrown back to the starting-point which requires the hopeful energy of youth—to feel one half of life gone, and nothing done—nothing remaining of wasted opportunity, but the bitter recollection that it has been. Miss Hale, would rather not hear Mr. Lennox’s opinion of my affairs. Those who are happy and successful themselves are too apt to make light of the misfortunes of others.” “You are unjust,” said Margaret, gently. “Mr. Lennox has only spoken of the great probability which he believes there to be of your redeeming—your more than redeeming what you have lost—don’t speak till I have ended—pray don’t.” And collecting herself once more, she went on rapidly turning over some law papers, and statement of accounts in a trembling hurried manner. “Oh! here it is! and—he drew me out a proposal—I wish he was here to explain it—showing that if you would take some money of mine, eighteen hundred and fifty-seven pounds, lying just at this moment unused in the bank, and bringing me in only two and a half per cent.—you could pay me much better interest, and might go on working Marlborough Mills.” Her voice had cleared itself and become more steady. Mr. Thornton did not speak, and she went on looking for some paper on which were written down the proposals for security; for she was most anxious to have it all looked upon in the light of a mere business arrangement, in which the principal advantage would be on her side. While she sought for this paper, her very heart-pulse was arrested by the tone in which Mr. Thornton spoke. His voice was hoarse, and trembling with tender passion, as he said:— “Margaret!” For an instant she looked up; and then sought to veil her luminous eyes by dropping her forehead on her hands. Again, stepping nearer, he besought her with another tremulous eager call upon her name. “Margaret!” Still lower went the head; more closely hidden was the face, almost resting on the table before her. He came close to her. He knelt by her side, to bring his face to a level with her ear; and whispered—panted out the words:— “Take care.—If you do not speak—I shall claim you as my own in some strange presumptuous way.—Send me away at once, if I must go;—Margaret!—” At that third call she turned her face, still covered with her small white hands, towards him, and laid it on his shoulder, even hiding it there; and it was too delicious to feel her soft cheek against his, for him to wish to see either deep blushes or loving eyes. He clasped her close. But they both kept silence. At length she murmured in a broken voice: “Oh, Mr. Thornton, I am not good enough!” “Not good enough! Don’t mock my own deep feeling of unworthiness.” After a minute or two he gently disengaged her hands from her face, and laid her arms as they had once before been placed to protect him from the rioters. “Do you remember, love?” he murmured. “And how I requited you with my insolence the next day?” “I remember how wrongly I spoke to you,—that is all.” “Look here! Lift up your head. I have something to show you!” She slowly faced him, glowing with beautiful shame. “Do you know these roses?” he said, drawing out his pocket-book, in which were treasured up some dead flowers. “No!” she replied, with innocent curiosity. “Did I give them to you?” “No! Vanity; you did not. You may have worn sister roses very probably.” She looked at them, wondering for a minute, then she smiled a little as she said— “They are from Helstone, are they not? I know the deep indentations round the leaves. Oh! have you been there? When were you there?” “I wanted to see the place where Margaret grew to what she is, even at the worst time of all, when I had no hope of ever calling her mine. I went there on my return from Havre.” “You must give them to me,” she said, trying to take them out of his hand with gentle violence. “Very well. Only you must pay me for them!” “How shall I ever tell Aunt Shaw?” she whispered, after some time of delicious silence. “Let me speak to her.” “Oh, no! I owe to her,—but what will she say?” “I can guess. Her first exclamation will be, ‘That man!’” “Hush!” said Margaret, “or I shall try and show you your mother’s indignant tones as she says, ‘That woman!’” About HackerNoon Book Series: We bring you the most important technical, scientific, and insightful public domain books.

Scientific American Supplement, No. 711, August 17, 1889, by Various, is part of the HackerNoon Books Series. You can jump to any chapter in this book . SUCCESSION OF FOREST GROWTHS. here SUCCESSION OF FOREST GROWTHS. The following is from an address delivered by Mr. Robert Douglas before the Association of American Nurserymen at the meeting in Chicago recently. It is the prevailing and almost universal belief that when native forests are destroyed they will be replaced by other kinds, for the simple reason that the soil has been impoverished of the constituents required for the growth of that particular tree or trees. This I believe to be one of the fallacies handed down from past ages, taken for granted, and never questioned. Nowhere does the English oak grow better than where it grew when William the Conqueror found it at the time he invaded Britain. Where do you find white pines growing better than in parts of New England where this tree has grown from time immemorial? Where can you find young redwoods growing more thriftily than among their giant ancestors, nearly or quite as old as the Christian era? The question why the original growth is not reproduced can best be answered by some illustrations. When a pine forest is burned over, both trees and seeds are destroyed, and as the burned trees cannot sprout from the stump like oaks and many other trees, the land is left in a condition well suited for the germination of tree seeds, but there are no seeds to germinate. It is an open field for pioneers to enter, and the seeds which arrive there first have the right of possession. The aspen poplar ( ) has the advantage over all other trees. It is a native of all our northern forests, from the Atlantic to the Pacific. Even fires cannot eradicate it, as it grows in moist as well as dry places, and sprouts from any part of the root. It is a short-lived tree, consequently it seeds when quite young and seeds abundantly; the seeds are light, almost infinitesimal, and are carried on wings of down. Its seeds ripen in spring, and are carried to great distances at the very time when the ground is in the best condition for them. Even on the dry mountain sides in Colorado, the snows are just melting and the ground is moist where they fall. Populus tremuloides To grow this tree from seed would require the greatest skill of the nurseryman, but the burnt land is its paradise. Wherever you see it on high, dry land you may rest assured that a fire has been there. On land slides you will not find its seeds germinating, although they have been deposited there as abundantly as on the burned land. Next to the aspen and poplars comes the canoe birch, and further north the yellow birch, and such other trees as have provision for scattering their seeds. I have seen acorns and nuts germinating in clusters on burned lands in a few instances. They had evidently been buried there by animals and had escaped the fires. I have seen the red cherry ( ) coming up in great quantities where they might never have germinated had not the fires destroyed the debris which covered the seed too deeply. Prunus Pennsylvanica A careful examination around the margin of a burned forest will show the trees of surrounding kinds working in again. Thus by the time the short-lived aspens (and they are very short-lived on high land) have made a covering on the burned land, the surrounding kinds will be found re-established in the new forest, the seeds of the conifers, carried in by the winds, the berries by the birds, the nuts and acorns by the squirrels, the mixture varying more or less from the kinds which grew there before the fire. It is wonderful how far the seeds of berries are carried by birds. The waxwings and cedar birds carry seeds of our tartarean honeysuckles, purple barberries and many other kinds four miles distant, where we see them spring up on the lake shore, where these birds fly in flocks to feed on the juniper berries. It seems to be the same everywhere. I found European mountain ash trees last summer in a forest in New Hampshire; the seed must have been carried over two miles as the crow flies. While this alternation is going on in the East, and may have been going on for thousands of years, the Rocky Mountain district is not so fortunate. When a forest is burned down in that dry region, it is doubtful if coniferous trees will ever grow again, except in some localities specially favored. I have seen localities where short-lived trees were dying out and no others taking their places. Such spots will hereafter take their places above the timber line, which seems to me to be a line governed by circumstances more than by altitude or quality of soil. There are a few exceptions where pines will succeed pines in a burned-down forest. grows up near the timber line in the Rocky Mountains. This tree has persistent cones which adhere to the trees for many years. I have counted the cones of sixteen years on one of these trees, and examined burned forests of this species, where many of the cones had apparently been bedded in the earth as the trees fell. The heat had opened the cones and the seedlings were growing up in myriads; but not a conifer of any other kind could be seen as far as the fire had reached. Pinus Murrayana In the Michigan Peninsula, northern Wisconsin and Minnesota, , a comparatively worthless tree, is replacing the valuable red pine ( ), and in the Sierras and are replacing the more valuable species by the same process. P. Banksiana P. resinosa P. Murrayana P. tuberculata In this case, also, the worthless trees are the shortest lived. So we see that nature is doing all that she can to remedy the evil. Man only is reckless, and especially the American man. The Mexican will cut large limbs off his trees for fuel, but will spare the tree. Even the poor Indian, when at the starvation point, stripping the bark from the yellow pine ( ), for the mucilaginous matter being formed into sap wood, will never take a strip wider than one third the circumference of the tree, so that its growth may not be injured. P. ponderosa We often read that oaks are springing up in destroyed forests where oaks had never grown before. The writers are no doubt sincere, but they are careless. The only pine forests where oaks are not intermixed are either in land so sandy that oaks cannot be made to grow on them at all, or so far north that they are beyond their northern limit. In the Green Mountains and in the New England forests, in the pine forests in Pennsylvania, in the Adirondacks, in Wisconsin and Michigan—except in sand—I have found oaks mixed with the pines and spruces. In northwestern Minnesota and in northern Dakota the oaks are near their northern limit, but even there the burr oak drags on a bare existence among the pines and spruces. In the Black Hills, in Dakota, poor, forlorn, scrubby burr oaks are scattered through the hills among the yellow pines. In Colorado we find them as shrubs among the pines and Douglas spruces. In New Mexico we find them scattered among the piñons. In Arizona they grow like hazel bushes among the yellow pines. On the Sierra Nevada the oak region crosses the pine region, and scattering oaks reach far up into the mountains. Yet oaks will not flourish between the one hundredth meridian and the eastern base of the Sierras, owing to the aridity of the climate. I recently found oaks scattered among the redwoods on both sides of the Coast Range Mountains. Darwin has truly said, "The oaks are driving the pines to the sands." Wherever the oak is established—and we have seen that it is already established whereever it can endure the soil and climate—there it will remain and keep on advancing. The oak produces comparatively few seeds. Where it produces a hundred, the ash and maple will yield a thousand, the elm ten thousand, and many other trees a hundred thousand. The acorn has no provision for protection and transportation like many tree seeds. Many kinds are furnished with wings to float them on the water and carry them in the air. Nearly every tree seed, except the acorn, has a case to protect it while growing, either opening and casting the seeds off to a distance when ripe or falling with them to protect them till they begin to germinate. Even the equally large seeds of other kinds are protected in some way. The hickory nut has a hard shell, which shell itself is protected by a strong covering until ripe. The black walnut has both a hard shell and a fleshy covering. The acorn is the only seed I can think of which is left by nature to take care of itself. It matures without protection, falls heavily and helplessly to the ground, to be eaten and trodden on by animals, yet the few which escape and those which are trodden under are well able to compete in the race for life. While the elm and maple seeds are drying up on the surface, the hickories and the walnuts waiting to be cracked, the acorn is at work with its coat off. It drives its tap root into the earth in spite of grass, and brush, and litter. No matter if it is shaded by forest trees so that the sun cannot penetrate, it will manage to make a short stem and a few leaves the first season, enough to keep life in the root, which will drill in deeper and deeper. When age or accident removes the tree which has overshadowed it, then it will assert itself. Fires may run over the land, destroying almost everything else, the oak will be killed to the ground, but it will throw up a new shoot the next spring, the root will keep enlarging, and when the opportunity arrives it will make a vigorous growth, in proportion to the strength of the root, and throw out strong side roots, and after that care no more for its tap root, which has been its only support, than the frog cares for the tail of the tadpole after it has got on its own legs. There is no mystery about the succession of forest growths, nothing in nature is more plain and simple. We cannot but admire her wisdom, economy, and justness, compensating in another direction for any disadvantage a species may have to labor under. Every kind of tree has an interesting history in itself. Seeds with a hard shell, or with a pulpy or resinous covering which retards their germination, are often saved from becoming extinct by these means. The red cedar ( ) reaches from Florida to and beyond Cape Cod; it is among the hills of Tennessee, through the Middle States and New England. It is scattered through the Western States and Territories, at long distances apart, creeping up the Platte River, in Nebraska. (I found only three in the Black Hills, in Dakota, in an extended search for the different trees which grow there. Found only one in a long ramble in the hills at Las Vegas, New Mexico.) Yet this tree has crept across the continent, and is found here and there in a northwesterly direction between the Platte and the Pacific Coast. It is owing to the resinous coating which protects its seeds that this tree is found to-day scattered over that immense region.

SUCCESSION OF FOREST GROWTHS

LANGLEY, ALLEGHENY OBSERVATORY, PA. [1] When, with a powerful telescope, we return to the study of the sun's surface, we meet a formidable difficulty which our first simple means did not present. This arises from the nearly constant tremors of our own atmosphere, through which we have to look. It is not that the tremor does not exist with the smaller instrument, but now our higher magnifying power exaggerates it, causes everything to appear unsteady and blurry, however good the glass, and makes the same kind of trouble for the eye which we should experience if we tried to read very fine print across the top of a hot stove, whence columns of tremulous air were rising. There is no remedy for this, unless it is assiduous watching and infinite patience, for in almost every day there will come one or more brief intervals, lasting sometimes minutes, sometimes only seconds, during which the air seems momentarily tranquil. We must be on the watch for hours, to seize these favorable moments, and, piecing together what we have seen in them, in the course of time we obtain such knowledge of the more curious features of the solar surface as we now possess. The eye aches after gazing for a minute steadily at the full moon, and the sun's light is from 300,000 to 600,000 times brighter than full moon light, while its heat is in still greater proportion. The object lens of such a telescope as the equatorial at Allegheny is 13 inches in diameter, and it is such light, and such heat, concentrated by it, that we have to gaze on. The best contrivance so far found for diminishing both, and without which our present acquaintance with the real appearance and character of sunspots would not have been gained, depends upon a curious property of light, discovered by a French physicist, Malus, in the beginning of this century. Let A ( ) be a piece of plane unsilvered glass, receiving the solar rays and reflecting them to a second similar one, B, which itself reflects them again in the direction C. Of course, since the glass is transparent, most of the rays will pass through A, and not be reflected. Of those which reach B again most will pass through, so that not a hundredth part of the original beam reaches C. This then, is so far a gain; but of itself of little use, since, such is the solar brilliancy, that even this small fraction would, to an eye at C, appear blindingly bright. Now, if we rotate B about the line joining it with A, keeping always the same reflecting angle with it, it might naturally be supposed that the light would merely be reflected in a new direction unchanged in quantity. Fig. 10 But according to the curious discovery of Malus this is not what happens. What does happen is that the second glass, after being given a quarter turn (though always kept at the same angle), seems to lose its power of reflection almost altogether. The light which comes from it now is diminished enormously, and yet nothing is distorted or displaced; everything is seen correctly if enough light remains to see it by at all, and the ray is said to have been "polarized by reflection." It would be out of place to enter here on the cause of the phenomenon; the fact is certain, and is a very precious one, for the astronomer can now diminish the sun's light till it is bearable by the weakest eye, without any distortion of what he is looking at, and without disturbing the natural tints by colored glasses. In practice, a third and sometimes a fourth reflector, each of a wedge shaped, optically plane piece of unsilvered glass, are thus introduced, and by a simple rotation of the last one the light is graded at pleasure, so that with such an instrument, called "the polarizing eyepiece" ( ), I have often watched the sun's magnified image for four or five hours together with no more distress to the eye than in reading a newspaper. Fig. A With this, in favorable moments, we see that the sun's surface away from the spots, everywhere, is made up of hundreds of thousands of small, intensely brilliant bodies, that seem to be floating in a gray medium, which, though itself no doubt very bright, appears dark by comparison. What these little things are is still uncertain; whatever they are, they are the immediate principal source of the sun's light and heat. To get an idea of their size we must resort to some more delicate means of measurement than we used in the case of the watch. The filar micrometer consists essentially of two excessively fine strands of cobwebs (or, rather, of spider's cocoon), called technically "wires," stretched parallel to each other and placed just at the focus of the telescope. Suppose one of them to be fixed and the second to be movable (keeping always parallel to the first) by means of a screw, having perhaps one hundred threads to the inch, and a large drum shaped head divided into one hundred equal parts, so that moving this head by one division carries the second "wire" 1/10000 part of an inch nearer to the first. Motions smaller than this can clearly be registered, but it will be evident that everything here really depends upon the accuracy of the screw. The guide screw of the best lathe is a coarse piece of work by comparison with "micrometer" screws as now constructed (especially those for making the "gratings" to be described later), for recent uses of them demand perhaps the most accurate workmanship of anything in mechanics—the maker of one which will pass some lately invented tests is entitled at any rate to call himself "a workman." Since the "wires" are stretched precisely in the focus, where the principal image of the sun is formed, and move in it, they, and the features of the surface, form one picture, as magnified by the eye lens, so that they appear as if moving about on the sun itself. We can first set them far enough apart, for instance, to take in the whole of a spot, and then by bringing them together measure its apparent diameter, in ten thousandths of an inch. Then, measuring the diameter of the whole sun, we have evidently the proportion that one bears to the other, and hence the means of easily calculating the real size. A powerful piece of clockwork, attached to the equatorial, keeps it slowly rotating on its axis, at the same angular rate as that with which the sun moves in the sky, so that any spot or other object there will seem to stay fixed with relation to the "wires," if we choose, all day long. The picture of "wires," spots, and all, may be projected on a screen if desired; and shows the field of view, with the micrometer wires lying across a "spot," so seen on the 6th of March, 1873. Part of a cambric needle with the end of a fine thread is represented also as being projected on the screen along with the "wires" to give a better idea of the delicacy of the latter. Fig. 11 Now we may measure, if we please, the size of one of those bright objects, which have just been spoken of as being countable by hundreds of thousands. These "little things" are then seen to be really of considerable size, measuring from one to three seconds of arc, so that (a second of arc here being over 400 miles) the average surface of each individual of these myriads is found to be considerably larger than Great Britain. Near the edge of the disk, under favorable circumstances, they appear to rise up through the obscuring atmosphere, which darkens the limb, and gathered here and there in groups of hundreds, to form the white cloudlike patches ( ), which may sometimes be seen even with a spy-glass—"something in the sun brighter than the sun itself," to employ the expression by which Huyghens described them nearly two hundred years ago. They are too minute and delicate objects to be rendered at all in our engraving; but this is true also of much of the detail to be seen at times in the spots themselves. The wood cuts make no pretense to do more than give an outline of the more prominent features, of which we are now about to speak. The wonderful beauty of some of their details must be taken on trust, from the writer's imperfect description of what no pencil has ever yet rendered and what the photograph has not yet seized. faculæ Bearing this in mind, let us now suppose that while using the polarizing eyepiece on the part of the spot distinguished by the little circle, we have one of those rare opportunities when we can, by the temporary steadiness of our tremulous atmosphere, use the higher powers of the telescope and magnify the little circle till it appears as in . We have now nearly the same view as if we were brought close to the surface of the sun, and suspended over this part of the spot. All the faint outer shade, seen in the smaller views (the ) is seen to be made up of long white filaments, twisted into curious ropelike forms, while the central part is like a great flame, ending in fiery spires. Over these hang what look like clouds, such as we sometimes see in our highest sky, but more transparent than the finest lace vail would be, and having not the "fleecy" look of our clouds, but the appearance of being filled with almost infinitely delicate threads of light. Perhaps the best idea of what is so hard to describe, because so unlike anything on earth, is got by supposing ourselves to look successive vails of white lace, filled with flower-like patterns, at some great body of white flame beyond, while between the spires of the flame and separating it from the border are depths of shade passing into blackness. With all this, there is something crystalline about the appearance, which it is hard to render an idea of—frost-figures on a window pane may help us as an image, though imperfect. In fact the intense whiteness of everything is oddly suggestive of something very cold, rather than very hot, as we know it really. I have had much the same impression when looking into the open mouth of a puddling furnace at the lumps of pure white iron, swimming half-melted in the grayer fluid about them. Here, however, the temperature leaves nothing solid, nothing liquid even; the iron and other metals of which we know these spot-forms do in part at least consist are turned into vapor by the inconceivable heat, and everything we are looking at consists probably of clouds of such vapor; for it is fluctuating and changing from one form into another while we look on. Forms as evanescent almost as those of sunset clouds, and far more beautiful in everything but color, are shifting before us, and here and there we see, or think we see, in the sweep of their curves beyond, evidences of mighty whirlwinds (greater by far than the largest terrestrial cyclone) at work. While we are looking, and trying to make the most of every moment, our atmosphere grows tremulous again, the shapes get confused, there is nothing left distinct but such coarser features as our engraving shows, and the wonderful sight is over. When we consider that this little portion of the spot we have been looking at is larger than the North and South American continents together, and that we could yet see its parts change from minute to minute, it must be evident that the actual motion must have been rapid almost beyond conception—a speed of from 20 to 50 miles a being commonly observed and sometimes exceeded. (A cannon ball moves less than ¼ of a mile per second.) I have seen a portion of the photosphere, or bright general surface of the sun, drawn into a spot, much as any floating thing would be drawn into a whirlpool, and then, though it occupied by measurement over 3,000,000 miles in area, completely break up and change so as to be unrecognizable in less than twenty minutes. Fig. 12 penumbra through second When we come to discuss the subject of the sun's heat, we shall find that the temperature of a blast furnace or of the oxyhydrogen blowpipe is low compared with that which obtains all over such a vast region, and remembering this, it is evident that its disappearance is a cataclysm of which the most tremendous volcanic outburst here gives no conception. We cannot, by any terrestrial comparison, describe it, for we have no comparison for it in human experience. If we try to picture such an effect on the earth, we may say in another's words that these solar whirlwinds are such as, "coming down upon us from the north, would in thirty seconds after they had crossed the St. Lawrence be in the Gulf of Mexico, carrying with them the whole surface of the continent in a mass, not simply of ruin, but of glowing vapor, in which the vapors arising from the dissolution of the materials composing the cities of Boston, New York, and Chicago would be mixed in a single indistinguishable cloud." These vast cavities then in the sun we call spots are not solid things, and not properly to be compared even to masses of slag or scoria swimming on a molten surface. They are rather rents in that bright cloud surface of the sun which we call the photosphere, and through which we look down to lower regions. Their shape may be very rudely likened to a funnel with sides at first slowly sloping (the ), and then suddenly going down into the central darkness (the ). This central darkness has itself gradations of shade, and cloud forms may be seen there obscurely glowing with a reddish tinge far down its depths, but we never see to any solid bottom, and the hypothesis of a habitable sun far within the hot surface, suggested by Sir William Herschel, is now utterly abandoned. We are able now to explain in part that mysterious feature in the sun's rotation before insisted on, for if the sun be not a solid or a liquid, but a mass of glowing vapor, it is evidently possible that one part of it may turn faster than another. it so turns, we repeat, no one knows, but the fact that it does is now seen to bear the strongest testimony to the probable gaseous form of the sun throughout its mass—at any rate, to the gaseous or vaporous nature of everything we see. We must not forget, however, that under such enormous temperature and pressure as prevail there the conditions may be—in fact, must be—very different from any familiar to us here, so that when we speak of "clouds," and use like expressions, we are to be understood as implying rather an analogy than an exact resemblance. penumbra umbra Why We must expect, with the great advances photography has lately made, to know more of this part of our subject (which we may call solar meteorology) at the next spot maximum than ever before, and by that time it may be hoped that some of the wonderful forms described above so imperfectly will have been caught for us by the camera. In the notice in our issue for July 27 of a new screw cutting lathe made by Messrs. Goodnow & Wightman, the address should have been 176 Washington street instead of 128, and the diameter of the tail spindle, which was given as 5/16, should have been 15/16 inch. The Olympia (Wyoming Territory) announces that a company has been formed there to bring ice from a glacier. The deposit covers a number of acres, is seventy or eighty feet deep, and is supposed to contain a hundred thousand or more tons, some of which may have been there as many years. The ice can be cut and sold at one and one half cents a pound, and by the ship load at five dollars a ton.

HackerNoon’s Legal PDF Series here Introduction Microsoft Corporation appeals from orders of the United States District Court for the Southern District of New York (1) denying Microsoft’s motion to quash a warrant (“Warrant”) issued under the Stored Communications Act, 18 U.S.C. §§ 2701 et seq., to the extent that the orders required Microsoft to produce the contents of a customer’s e‐ mail account stored on a server located outside the United States, and (2) holding Microsoft in civil contempt of court for its failure to comply with the Warrant.  We conclude that § 2703 of the Stored Communications Act does not authorize courts to issue and enforce against U.S.‐based service providers warrants for the seizure of customer e‐mail content that is stored exclusively on foreign servers.

SUSAN L. CARNEY, Circuit Judge: Microsoft Corporation appeals from orders of the United States District Court for the Southern District of New York denying its motion to quash a warrant (“Warrant”) issued under § 2703 of the Stored Communications Act (“SCA” or the “Act”), 18 U.S.C. §§ 2701 et seq., and holding Microsoft in contempt of court for refusing to execute the Warrant on the government’s behalf.  The Warrant directed Microsoft to seize and produce the contents of an e‐mail account that it maintains for a customer who uses the company’s electronic communications services.  A United States magistrate judge (Francis, M.J.) issued the Warrant on the government’s application, having found probable cause to believe that the account was being used in furtherance of narcotics trafficking.  The Warrant was then served on Microsoft at its headquarters in Redmond, Washington. Microsoft produced its customer’s non‐content information to the government, as directed.  That data was stored in the United States.  But Microsoft ascertained that, to comply fully with the Warrant, it would need to access customer content that it stores and maintains in Ireland and to import that data into the United States for delivery to federal authorities.  It declined to do so.  Instead, it moved to quash the Warrant.  The magistrate judge, affirmed by the District Court (Preska, C.J.), denied the motion to quash and, in due course, the District Court held Microsoft in civil contempt for its failure. Microsoft and the government dispute the nature and reach of the Warrant that the Act authorized and the extent of Microsoft’s obligations under the instrument.  For its part, Microsoft emphasizes Congress’s use in the Act of the term “warrant” to identify the authorized instrument.  Warrants traditionally carry territorial limitations:   United States law enforcement officers may be directed by a court‐issued warrant to seize items at locations in the United States and in United States‐controlled areas, see Fed. R. Crim. P. 41(b), but their authority generally does not extend further. The government, on the other hand, characterizes the dispute as merely about “compelled disclosure,” regardless of the label appearing on the instrument.  It maintains that “similar to a subpoena, [an SCA warrant] requir[es] the recipient to deliver records, physical objects, and other materials to the government” no matter where those documents are located, so long as they are subject to the recipient’s custody or control.  Gov’t Br. at 6.  It relies on a collection of court rulings construing properly‐ served subpoenas as imposing that broad obligation to produce without regard to a document’s location.  E.g., Marc Rich & Co., A.G. v. United States, 707 F.2d 663 (2d Cir. 1983). For the reasons that follow, we think that Microsoft has the better of the argument.  When, in 1986, Congress passed the Stored Communications Act as part of the broader Electronic Communications Privacy Act, its aim was to protect user privacy in the context of new technology that required a user’s interaction with a service provider.  Neither explicitly nor implicitly does the statute envision the application of its warrant provisions overseas.  Three decades ago, international boundaries were not so routinely crossed as they are today, when service providers rely on worldwide networks of hardware to satisfy users’ 21st–century demands for access and speed and their related, evolving expectations of privacy. Rather, in keeping with the pressing needs of the day, Congress focused on providing basic safeguards for the privacy of domestic users.  Accordingly, we think it employed the term “warrant” in the Act to require pre‐disclosure scrutiny of the requested search and seizure by a neutral third party, and thereby to afford heightened privacy protection in the United States.  It did not abandon the instrument’s territorial limitations and other constitutional requirements.  The application of the Act that the government proposes ― interpreting “warrant” to require a service provider to retrieve material from beyond the borders of the United States ―would require us to disregard the presumption against extraterritoriality that the Supreme Court re‐stated and emphasized in Morrison v. National Australian Bank Ltd., 561 U.S. 247 (2010) and, just recently, in RJR Nabisco, Inc. v. European Cmty., 579 U.S. __, 2016 WL 3369423 (June 20, 2016).  We are not at liberty to do so. We therefore decide that the District Court lacked authority to enforce the Warrant against Microsoft.  Because Microsoft has complied with the Warrant’s domestic directives and resisted only its extraterritorial aspects, we REVERSE the District Court’s denial of Microsoft’s motion to quash, VACATE its finding of civil contempt, and REMAND the cause with instructions to the District Court to quash the Warrant insofar as it directs Microsoft to collect, import, and produce to the government customer content stored outside the United States.
