In the English scientific journal , of June 21, 1878, appears a six column article on "Edison's Carbon Telephone," illustrated with ten engravings from Mr. Prescott's recent work on "The Speaking Telephone, Talking Phonograph, and other novelties." The descriptions of the cuts, and the rest of the information given, so far as correct, obviously come from the same source. Engineering So far as correct: unhappily for the honor of scientific journalism, the writer's desire is plainly not so much to do justice to truth as to exalt Mr. Hughes at the expense of Mr. Edison. To this end he has studiously suppressed from Mr. Prescott's description of the carbon telephone the points which establish Mr. Edison's claim to the prior invention or discovery of everything involved in Mr. Hughes' microphone, while he has as studiously dwelt upon those same points as constituting the peculiar merits of Mr. Hughes' work. For example, while he uses Fig. 21 of Mr. Prescott's book, he leaves out the very important little diagram numbered 20. It represents one form of the apparatus to which Sir William Thomson refers in the letter in which he says: "It is certain that at the meeting of the British Association at Plymouth last September, a method of magnifying sound in an electric telephone was described as having been invented by Mr. Edison, which was identical in principle and in some details with that brought forward by Mr. Hughes." The figure looks altogether too much like one form of Mr. Hughes' microphone to allow of its use in an article intended to establish the novelty of Mr. Hughes' discovery. The omissions from the text are quite as significant. Under the first cut used in , Mr. Prescott says: "In the latest form of transmitter which Mr. Edison has introduced the vibrating diaphragm is done away with altogether, it having been found that much better results are obtained when a rigid plate of metal is substituted in its place.... The inflexible plate, of course, merely serves, in consequence of its comparatively large area, to concentrate a considerable portion of the sonorous waves upon the small carbon disk or button; a much greater degree of pressure for any given effort of the speaker is thus brought to bear on the disk than could be obtained if only its small surface alone were used." Engineering The writer coolly suppresses this important statement. He does worse: he puts in its place the false statement that "the essential principle of Mr. Edison's transmitter consists in causing a diaphragm, vibrating under the influence of sonorous vibrations, to vary the pressure upon, and therefore the resistance of, a piece of carbon," and so on. Engineering A little further on, while repeating Mr. Edison's account of the experiments which led to the abandonment of the vibrating diaphragm (page 226 of Mr. Prescott's book), the writer drops out the following remark by Mr. Edison: "I discovered that my principle, unlike all other acoustical devices for the transmission of speech, did not require any vibration of the diaphragm—that, in fact, the sound waves could be transformed into electrical pulsations without the movement of any intervening mechanism." Engineering Worse yet, in the very face of Mr. Edison's assertion to the contrary—an assertion which he could not by any possibility have overlooked—this most unscientific journalist says: "Mr. Edison finds it necessary to insert a diaphragm in all forms of his apparatus, that being the mechanical contrivance employed by which sonorous vibrations are converted into variations of mechanical pressure, and by which variations in the conductivity of the carbon or other material is insured.... On the other hand, Mr. Hughes employs no diaphragm at all, the sonorous vibrations in his apparatus acting directly upon the conducting material or through whatever solid substance to which they may be attached." In this way throughout the offending article, the writer persistently robs Edison to magnify Hughes, giving credit to Mr. Hughes for exactly what he has suppressed from Mr. Prescott's book. To insist as he does, that, because Mr. Edison covers his carbon button with a rigid iron plate, in his very practical telephone, therefore a vibrating diaphragm is an essential feature of Mr. Edison's invention, is a very shallow quibble in the face of Mr. Edison's and Mr. Prescott's statements that the carbon button acts precisely the same in the absence of such covering, though not so strongly. Mr. Edison's laboratory records show a great variety of experiments in which the carbon was talked against without "any intervening mechanism." In a telephone for popular use, however, to be held in the hand, turned upside down, talked into, exposed to dust and the weather, it was obviously necessary to use some means for holding the carbon in place, and to prevent its sensitiveness from being destroyed by dirt and the moisture of the breath when in use. For this purpose a rigid iron partition seemed at once convenient and durable. It is not in any sense a "vibrating diaphragm." With a persistence worthy of a better cause, the writer returns to the point he seems especially anxious to enforce. Toward the end of the article he says: "In every instrument described by Mr. Edison the diaphragm is the ruling genie of the instrument. Professor Hughes, however, has through his great discovery been enabled to show that variations of resistance can be imparted to an electrical current not only without a diaphragm, but with very much better results when no such accessory is employed." Engineering The animus of all this is only too apparent. Altogether the article is the most dishonest piece of writing we have ever seen in a scientific periodical; and although the article appears in the editorial columns of , we prefer, for the honor of scientific journalism, to think that the management of that paper was not party to the rascally act. It is more credible that a gross imposition has been practiced by some trusted member of the staff, or by some contributor whose position seemed to justify the acceptance of his utterances without any attempt at their verification. It is well known here to whom, in London, at Mr. Edison's request, Mr. Prescott sent proofs of the matter abused, together with electros of the cuts used, in . Accordingly the burden of dishonor lies upon or between a prominent British official on the one hand, and on the other a journal which cannot afford to leave the matter unexplained. Whoever is hurt, we sincerely hope that the fair fame of scientific journalism for candor and honesty may come off unstained. Engineering Engineering Engineering A More Perfect Production. The highest skill in manufacture or in production of any kind is not yet the prevailing characteristic of American industry. Uniformity of production, of whatever kind, is of much greater importance than to attempt the manufacture of any grade for which the material or the tools, the machinery or the knowledge of the workmen is not fitted. The highest condition of product in any nation is to produce the finest or highest cost articles in the most perfect manner, and to have material and machinery adopted, and the skilled workmen, so as to be able to so produce economically. But until the master hand is satisfied of all the requisites for producing fine goods, he should confine production to the best his facilities will make in the most perfect, uniform manner. Samples of fine goods are shown all over the country every day, and were consumers or merchants sure that the product would be the same, there would be much less difficulty in introducing and more homemade goods used where now importations are depended upon. The Stevens crash mills import raw flax because it is to be had according to sample, perfectly classified, and saves the employment of skilled labor to assort and classify, and of purchasing a great deal not wanted. The manufacturers of edge tools and knives use imported steel because it is warranted and the warrant proves good, while the uncertainty of American steel is such that a knife will often crack in tempering and cause the loss of labor worth ten times the difference in the price of the steel. Samples of alpacas and other dress goods are shown in our jobbing houses fully equal to any imported goods, but the goods when received are quite often of various grades and imperfections of character. The imperfect or second quality productions find sale, but at a much lower price, and are to be found at second rate places, the imperfections slight and the goods perhaps generally quite as serviceable, but not absolutely so, and first class houses, catering to those who pay highest prices, cannot afford to have any other house carry better articles than they do. The use of perfect appliances and the best material and the employment of the highest skill are not yet the first step and an absolute necessity, as it should be, in America. The supply of such machinery, material, and labor can be had if those who propose to enter the production of first class articles will insist upon it, and if such supplies are appreciated by the payment of their higher value. The American standard of production is not the highest, and it can be materially elevated, and while, as at present, too many common articles are supplied, the leading manufacturers should turn to producing finer, the finest, and in smaller quantities, to take the place of many articles now imported, and to supply the new market which such productions will always create in any country. The Wool Product of the World. From an interesting article on the wool trade of the Pacific coast, published in a recent number of the San Francisco , we learn that the number of sheep in the world is now estimated at from four hundred and eighty-four to six hundred millions, of which the United States has about 36,000,000, and Great Britain the same number. From 1801 to 1875 the wool clip of Great Britain and Ireland increased from 94,000,000 to 325,000,000 pounds. That of France has increased almost as rapidly, though the wool is finer, as a rule, and hence the superiority of French cloths. Australia produces nearly as much wool as the parent country—Great Britain. The United States product increased from very little at the beginning of the century to about 200,000,000 pounds at the present time. Of this California has produced about one fourth, and the Pacific coast as a whole almost one third. If the ratio of growth shown in the past prevails in the future, the day is not far distant when the Pacific coast will produce at least one half the wool produced in the United States, as not only California and Oregon, but also Washington, Idaho, Montana, Utah, and New Mexico are well adapted to its production. The wool clip of Australia is about 284,000,000 pounds; that of Buenos Ayres and the river Plata, 222,500,000 pounds; other countries not previously given, 463,000,000 pounds. The total clip of the world last year was about 1,497,500,000 pounds, worth $150,000,000. This when scoured would yield about 852,000,000 pounds of clean wool. Journal of Commerce Street Main Joints. At the annual meeting of the New England Association of Gas Engineers, Mr. Thomas, of Williamsburg, made the following remarks on this subject: "In my early experience with the Williamsburg Gaslight Company, with which I became connected in the year 1854, I found pretty nearly all the street mains that were laid were connected with cement joints. While there is no doubt in my own mind that a joint can be made perfectly tight with cement, I much prefer the lead joint. Another thing to be taken into consideration to keep tight joints is that the mains should be laid a sufficient depth under the surface to protect them from the action of severe frosts. A great many of the mains were not more than 18 inches or 2 feet below the surface of the streets, and at this depth in our climate it is a matter of impossibility to keep joints tight, as the action of the frost in winter will displace the mains and cause the joints to leak. From the bad manner in which our mains were laid, and the cement joints leaking so much, we could not afford to turn gas on during the day. Had we done so we should not have had any to supply the city at night, and we were thus compelled to shut off the gas just as soon as there was any apology for daylight, and keep it shut off as late as possible in the evening. "With the most careful working in this manner, for a period of nine or twelve months, our losses from leakage amounted to about 52 to 55 per cent of the gas manufactured. A great part of this loss was caused by the cement joints leaking, and also a part due to the fact that the mains were not at sufficient depth under the surface to protect them from the action of the frost. As soon as we possibly could I went over the whole of our mains (there was about 17 miles in all), stripping them, cutting out the cement, and rejointing them with lead. In one season we got the loss from leakage down to 20 per cent, and this with the gas turned on during the 24 hours of the day. "One great objection to cement joints is the rigidity of them; in cases where pipes have been disturbed by other excavations and settled, I found in all cases that the mains were broken. In a leading main from our old works, with cement joints, the main, a 10-inch one, was broken entirely off and fractured lengthwise besides, by the upheaval of the ground from frost. In some of the same mains that we had rejointed with lead the mains were drawn apart, drawing the lead out, but with very little loss of gas, as the gasket being driven in tight prevented any great leakage. In cases of this kind the lead was easily driven back, and the joint made perfectly tight again. I have never in our city put in any street mains that I have not used lead in the joints, and in laying mains we always make them gas tight with the gasket used. "At the present time we have over 90 miles of street mains laid, and outside of our loss from street lamps (we get paid for three foot burners and they average about 3¼ foot) our loss from leakage will not exceed 6 per cent. We have suffered severe loss of gas from sewering in our city. In some cases where there are railroad tracks in the streets, the sewers have been run on both sides of the street, alongside and parallel with our pipes; these excavations are much deeper than our mains lie, and the earth is always filled in loosely and left to settle. "In cases of this kind, whole blocks of mains were dragged down, the pipe broken, and the joints partially pulled apart; at the same time the leakage from the joints was not so great, the gasket preventing the leakage. In laying street mains, what you want particularly to attend to, and especially in the East here, where you have colder weather than we have (we have not seen much winter until we came on here), is to get them down under the surface a sufficient depth to protect them from the frost. With us the least depth is 2 feet 9 inches under the surface of the street, and I am confident, could our mains remain in the ground as we put them down, our loss from leakage by them would be very small indeed. While, as I stated in the beginning, I have no doubt that a cement joint can be made tight, I can see no benefit in using cement for the purpose, as I consider lead far superior in accommodating itself to any upheaval or settling of the earth where the mains are laid down." Successful Shad Hatching. Professor J. W. Milner, who has charge of the shad hatching operations under the direction of the United States Fish Commissioner, Professor Baird, is now engaged in the preparation of the report of the work for the season just completed. Speaking of the work on the Atlantic seaboard, and the distribution of young fish, the report says that at the Salmon Creek Station, on Albemarle Sound, they obtained 12,730,000 eggs, and turned out 3,000,000 young fish. At the Havre de Grace Station 12,230,000 eggs were obtained, and 9,575,000 young fish were turned out. About 6,000,000 young shad have been distributed in the rivers emptying into the Atlantic and Gulf of Mexico during the season. The distribution of shad during the past season has been carried on on a much larger scale than in any previous year, and with great success. The restocking of the rivers of the Atlantic is only the work of a few years. New Use for Lemon Verbena. The well known fragrant garden favorite, the sweet-scented or lemon verbena ( ), seems to have other qualities to recommend it than those of the fragrance for which it is usually cultivated. The author of a recent work, entitled "Among the Spanish People," describes it as being systematically gathered in Spain, where it is regarded as a fine stomachic and cordial. It is used either in the form of a cold decoction, sweetened, or five or six leaves are put into a teacup, and hot tea poured upon them. The author says that the flavor of the tea thus prepared "is simply delicious, and no one who has drunk his Pekoe with it will ever again drink it without a sprig of lemon verbena." And he further states that if this be used one need "never suffer from flatulence, never be made nervous or old-maidish, never have cholera, diarrhea, or loss of appetite."
