Qood HbVTH Are New Houses Safe? It is a very general opinion that a long time is needed for a newly built bouse to become thoroughly dry, and that it is not safe to live in one for several months (some say a year) after it is bnilt. Popular opinions bave gen erally some fonndation, and I am anxious to know wbetber this opinion is correct, or bow far it is correct. I bave Bbares in two associations formed to provide better and more wholesome dwellings, especially for the working classes, and I hope we have succeeded, for the death rate amongst onr tenants is considerably below the average, partly owing, no donbt, to our tenants being generally of sober and steady habits, for we value peace and quietness, and so do they. We let onr houses very soon after they are finished, and in reply to my inquiries I am told that the inmates of the newly built bouses are quite as healthy as the others. We bave taken unusual care to have every room well ventilated, which may account for the absence of apparent in jury from damp, but I am not quite satisfied that we are acting prudently. I should like to be advised, if we are not, by those of wider ex perience. The dampness of walls arises not only or chiefly from the water absorbed, but rather from mat comoinea wun tne iinie in tne iorm of hydrate used for mortar and plaster. This combined water is displaced by carbonio acid, absolutely converting the hydrate of lime into carbonate, and it has been suggested that this change should be hastened, so tunc tne nouses 'mav become dry more quickly by keeping the rooms filled with carbonic acid by bumlugcole or charcoal in them so as to nil tbe rooms with their fumes. This sounds feasible, but is there no danger of 'the conversion of tbe hydrate into carbonate being too rapid, and the result being a product more resembling friable chalk than hard limestone? What is done too quickly is not done well. Is this change done too quickly to be done well? I am inclined to believe that the experience of our two associations proves that it is pos sible to avoid danger from the dampness of new houses by passing air through them rap idly enough to prevent its becoming saturated with moisture. Air which oontains no watery vapor is neither pleasant nor wholesome. It should be about two-thirds saturated, and if this proportion be not much exceeded no in jury can arise from such 'vapor only, and there seems no reason why, if it be derived from a damp wall, it should be injurious if not in ex cess!, e , if the air be ohanged rapidly enough to prevent it becoming damp. Ex. Fobce and Stimoxants. TheLondon Zancef remarks that at the present day our treatment has assumed a character too decidedly stimu lant and not quite sufficiently nutritive. Stimu lants ought to be regarded as auxiliaries to nu trition more than they are at present. Nutri tive material, as milk, meat juice, eggs, and various forms of starch, ought to form a greater matter in tbe dietary of the Bicfc than stimu lants, whether nitrogenized or alcoholic; such materials, when assimilated, give supplies of force. Stimulants may assist in their assimi lation, and do so; but in themselves stimulants only furnish limited supplies of force-bearing material. They are, however, a means by which the system may reach some of its physio logical reserve fund. Such use may be advan tageous or pernicious, according to circum stances; and an ill-regulated or excessive pro cess of stimulation may give results as dis astrous as a wise and intelligent resort to stim ulants may be beneficial ana preservative in its consequences. Beef Extract fob Invalids. To half a pound of beef or fowl recently killed, and chopped fine, add one pint of cold boiled water, to which four drops of hydrochlorio acid and one-eighth ounce common salt should also be added. After the mixture has stood an hour, throw it npon a hair sieve, or piece of mus lin, allowing it to drain without pressure. The first portion passing is usually turbid, and must be returned to the sieve until it runs clear. When all the liquor has been drained off, gently pour one-fourth pint of water, in small lots at a time, upon the residual minced flesh, allowing it to Tun into the liquid collected. In this way will be obtained about three-fourths of a pint of cold extract of flesh, of a red oolor, and of a pleasant, soup-like taste. Dose, one teacupful at a time, cold. It must not be warmed, and should be prepared fresh every twelve honrs, as heat will cause decomposition and the sep aration of a solid mass of coagulated albumen. Domestic Ecofiopv- Rye How to Cook and Eat It. Bye is not as much grown as of yore, yet it is a staple product in many localities, and tbe fol lowing receipts for rye cookery, contributed to a late number of Science of Health by Mi6s Julia Colman, will prove of interest and value to many readers; Rye Gems. Take ice cold water, as for wheat gems, and stir in good rye meal, entirely unbolted, sifting with one hand, stirring with the other.until they are of a consistency much thicker than that required for wheat. Experiment with a few at first, making some thicker than the others (tbe last about as thick as you can well stir them), so as to be sure to get the right consistency be fore making tbem for the table. Then bake them a little more than you wonld wheat, and serve warm or cold as you prefer. We like them warm. , " , "J .Bye and Wheat Gems. . . Those who do not fanoy so much of the rye taste, may soften it a little by putting in one third wheat and then 'making them into gems, precisely as for wheat or rye alone, making them not quite so thick as the latter. Rye and Indian Gems. TbeBe are made very much like the rye gems, only one-fourth of the meal should be corn Meal, of medium fineness. It does very well without scalding, though in that case it should be baked very thoroughly. If scalded, it should be mixed so thick that the gems need to be smoothed with a wet spoon before putting tbem into the oven. Otherwise tbey will seem soft and mushy. If rather soft, let them stand some minutes after tbey are out of the oven be fore serving them. This will do them more good than trying to bake them in the oveu. Rye and Indian Leal. Take two quarts of coarse corn meal, wet it thoroughly with two quarts of boiling water, add two quarts of rye meal, mix intimately, make into a loaf three or four Inches deep, or, if convenient, put into Boston brown bread pans, plaoe on top of the stove, where it is barely hot enough to make it simmer, let it stand here until it crack well over the surface, say an hour and a half or two hours. Then put into a hot oven, bake two or three hours, according to the size of the loaf, then cool the oven gradually, or take a loaf out and steam it an hour or two. Rye Mush. If the rye meal or rye Graham be course, aif it into boiling water with one hand, stirring with the other. If it be fine, pour the mral into boiling water and stir vigorously until thoroughly wetted and of the consistency you wish it when done. Then in either case, cover clcse and set it where ft will cook slowly, from forty to sixty minutes or more. Dates may be added to this if desired, stoning them and stirring them in just before serving. Dress the plain mush with stewed currant. Rye and Indian Mush. Use two parts rather coarse corn meal and one part rye meal, stirring in the corn meal first and cooking a while if desired, then ad ding the rye meal, stirring very carefully, then cover close and cook slowly one hour or more. Vienna Yeast. The Vienna bread is reputed to be the best in the world. It is said to owe its superiority to the peculiar yeast employed, which is also used in the manufacture of the celebrated Vienna beer. This Viennese yean, acoording to the London Chemist and Druggist, ia nn.,vl fn iha fnllnwlnc wav!

An (..MLntfllinn nmnppaflAR the clobllleS of yeast reproduce themselves by a species of Duaamg, engendering hi uri " , " globules, but these rapidly increase in size. Carbonio acid is disengaged during the process with so much rapidity that globules of yeast are thrown up by the gas, and remain floating on the surface, where they form a thick scum. This scum is carefully removed, and constitutes the best and purest yeast. When drained and compressed by a hydraulic press, it can be kept from eight to fifteen days, according to the season. Hakleodtn Jellyl With the extra refined gelatine, make a gallon of clear jelly; color with vaiious fruit dyes. The juice ex tracted from spinach leaves will give a fine green ; cochineal, red ; the zest of orange, rubbed on crystal sugar, yellow. These, with various colors from fruit jellies, will afford a number of hues. Have a large mold, into which put the various colored jellies in an almost solid state, to prevent their mingling. When full, set the mold aside until perfectly set, then turn it out on a glass dish, when tbe various colors will be found tastefully blended and marbled. These vari-colored dishes are very ornamental to the table. SrEEf iijiD Wool. Blood Diseases Among Lambs. From various districts we learn that losses of greater or less numbers have been taking place among lambs and sheep from an affection which exhibits similar signs in both parents and off spring. In tbe outset it appears the lambs were first to suffer, and they gave indications pf great pain, lameness, and subsequently swelling in a hind or fore quarter. Somewhat later a sero-sanguineous or blood and water discbarge issned from the affected part, and the animals died in from four to four and twenty hours. In one instance that has come beneath our notice, we areMnforined that the lambs were finely grown and in an excellent condition, and Bhortly after the Uils were amputated the mor tality took place. Later, the sheep, which were subjected to the operation of clipping, have also become affected, and after suffering in an identical manner, die off as the lambs did. From a oareful consideration of the details as they reached us, we do not hesitate to conclude the disease in both young and old animals is the same a blood poison, known as black quarter, quarter felon, black pauld, eto. It will not be without interest if we examine what connection there may be existing between the appearance of the disease and tbe opera tion. There cannot possibly arise any ques tion of probability that either dosking or clip ping were the causes primarily, but that both were instrumental in hastening the develop ment of conditions necessary for the outbreak of tbe disease, is not at all unlikely. The lambs after losing their tiils, may possibly have moved about less, and thus favored local con gestion, and the sheep alter losing their fleece, being deprived of that which requires much support, possess within themselves a larger amount of rich blood than is needed. Besides, ihe skin without the fleece would be It si vigorous in throwing off the impurities of tbe body, and thus an additional cause of blood poisoning would arise. But the primary and necessary causes are of anterior date alto gether. .When tbe body is charged with a superabundance of morbid elements, many simple conditions, as operation, change of food, pasture, eto., unnoticed and innocuous at other times, suddenly swell jn tbe list of im portant collateral agents in the production of general disease. There is very much to be taken into consideration in relation to food, water, manure, drainage locality, age of past ure, etc. Edinburqh Farmer. Eastern Wool Markets.

Cafi. WILLAMETTE FARMER. ty!lSCELUMEOiJS( Production of Bessemer Steel United States. in the The eight completed Bessemer steel works in this country.though doing a good bnsine8swere not fully occupied during the year 1874. The production ot this class of steel in the United States is rapidly increasing. Starting in 18C7, with a production of only 3,000 tons, we find the productionin 1874 has reached 170,579 tons. The rate of increase will be seen by the follow ing tabular statement: 1867 3.000 1868 8.SL0 18C9 11,000 1870 40,100 1871 45,000 1872 110,000 1873 157,000 1874 176,000 Of the total nroduct durinc 1874. there were 144,944 tons employed in the manufacture of steel rails. Tne iJl.uaa tons nor, so useu, were employed in the manufacture of spring and bar steel railway axles, crowbars and other railway tools, wagon and carriage tires, machinery and steamboat forgings, etc The English Product ol Bessemer Steel. The quantity of Bessemer steel made in the United Kingdom during tho past five years is stated as follows, by competent authority, in gross tons: In 1870,215,000; 1871, 329,000; 1872, 410,000; 1873, 49G.O0O; 1874, 610,000. We give these figures for comparison with our own achievements in building up the Bessemer industry, and that we may call attention to the fact that when the three new Bessemer establish ments are all put in operation making eleven in all the capacity to produoe Bessemer steel will be as great in this country as it now is in Great Britain. The Production of Steel other than Bessemer There are forty-two establishments in tbe United States, making cast, puddled, blister and open-hearth steel. The aggregate produc tion of these establishments in 1874 was 47,481 tons. The production of open-hearth or Siemens Martin steel is steadily increasing in the United States. There are now thirteen establishments here, which are using the Siemens-Martin fur nace, whose aggregate product is about 10,000 tons. In 1872 it was only 3,000 tons. As a further encouraging evidence of the rapid progress of steel making in this country, e clip the following extract from the American Manufacturer, from which journal wo have also condensed the above: During the calendar year 1874 our imports of steel ingots, bars, sheets and wire amounted to S2.G78.611, against $3,865,316 in 1873; $4,200, 087 in 1872; and $3,4G0,735 in 1871. Our ex ports of these nrticles in 1874 amounted to 313 net tons of the value of 829,557, against twenty-six ions in 1873 of the value of $5,481, nine tons in 1872 of the value of 3,G2i and thirty tons in 1871 of the value of $7,3G4. The in crease our exports and the decrease of our imports of these commodities in 1874 are very marked, and the statistics of the exports and imports of the manufactures of steel for 1874, are equally encouraging to the home manufacturer of steel or steel products. Magnetism. In ordinary observation, mag netism is scarcely known except as existing in iron, and especially in steel, and as related in some obscure manner to the earth. But there is reason to believe that it is one of the most extensively diffused agents in nature. It can be traced not only in iron, but also in every substance into which iron enters into composi tion. It is found in niokel, cobalt, chromium, and other substances, and even in some gases. Wherever a galvanio current exists in nature, whether produced by chemical action, or ap pearing in tbe thermo-electric, form as originating from the effects of heat at the place of union of different substances, magnetio ef fects can be elicited. On the larger scale, it is cer tain that the whole earth acts as a combination of magnets, and there is reason to think that the sun and the moon also act as magnets. The laws of magnetio foroe, however, have been ex perimentally examined with philosophical ac curacy, only in their connection with iron and stoel, and, by inferences bearing considerable probability, in tbe influences exerted by tbe earth aB a whole. The ferruginous minerals of the formula Fej Ot possess tbe property of at tracting iron and its filings, and are called nat ural magnets or lodestoues. Experience has demonstrated that tbe attractive action of mag nets takes place in a vacuum and through all bodies, whether gaseous, liquid, or solid, when they are not themselves magnetic. All the properties of natural magnets may be perma nently communicated to needles or to bars of steel oroperlv tempered, which are then said to be magnetized, and take the name of artificiul magnets. ScienVJte American. Engineering Feat. A remarkable feat of ,engineeriug has recently been accomplished by Mesbrs. weeKs az lsro.., wen Known Duuuers in this city. This feat consisted in the removal of a wall 65 f-et in bight, GO feet in length, ami of an average thiokuess of 14 inches. The wall having been found to fncrou-b upon neighbor ing property, it was necessary to take it down in the usual way and re-ereel it, or to adopt the alternative successfully carried out by Messrs. VWks & Bros. They carefully removed tbe masonry wbtcb joined the wall to the rest of the building, and pierced the wall at the bot tom with holes, into which a double set of needlw beams were inserted. These beams formed ways upon which the wall was slid along. The beams were thoroughly greased and shoes placed upon them. The entire weinht of the wall retted upon these shoes. Screw- jacks we're then applied and carefully manipu lated fy trained worainen, u mai wuue uii wall was slid bodily along its parallelism with the opposite wall of the building and its per pendicularity were all the while maintained. ,xhe entire .weight was said' to exceed 270 tons., After the preliminary preparations were 'made only about' five' hours nere absorbed in the re moval of the wall to the position it was destined to occupy. Tnla wall Has neen joined to me Building again, and u is Btaieu uiat a iure economy was the result of tbe operation. The successful removal of Ibis wall will doubilesa be the beginning of many similar removals. Messrs. Weeks &. tiros, nave exmoiiea great in genuityand skill. Our readers will compre hend that the utmost care was necessary to re move a wall of tbis kind, balanced upon so nar row a base, without toppling it over or crack ing it. JV. Y. Artisan. A Ram is not a Buck. The perfect male sheep is a ram, and not a buck, as it is too often designated by thoughtless writers and talkers. It wonld be just as proper to call the female sheep a doe, as it is to apply the term buck to the male. So common has tbe mistake become, that it scarcely attracts the attention of those who know better. In fact, with the exception of four States New York, Ohio, Illinois, and California even tbe boards con trolling the State fairs offer premiums for tbe "best backs" of the several brteds of sheep. In several of the extreme Western States and Territories the breeding of Angora goats is receiving attention, and unless nock-masters are a little more careful in the use of terras, considerable confusion is likely to ensue. JV. T. Timet, A New Self-Acting Saloon. The London Keus of a late date says: "An invention which has been favorably regarded by tbe leading authorities on the subject of channel navigation, and which notably is un der tbe attentive consideration of Mr. Mills, engineer in chief to tbe London, Chatham and Dover railway, with a view to its adoption by that company, was yesterday explained by its originator, Mr. Alexander Walker, O. E., to a party of professional and scientific gentlemen, assembled at the Terminus hotel, Cannon street. In order to understand the nature of Mr. Walker'B plan for accomplishing that great public benefit xhich has hitherto fallen short of practical attainment, we must imagine a lon gitudinal section of an ordinary passenger steamboat between Dover and Calais. Fore and aft we perceive two circular bell-shaped saloons each divided into three compartments. The middle spaoe is intended for tbe general use of the passengers, and the division on t ither side is severally for ladies and for gen tlemen. Each of these saloons is carried on a strong central shaft or spindle, which passes vertically through the saloon itself, then through a ball and sooket joint fixed in a rigid iron framing beneath the saloon floor, and so downward to a huge spherical counter-weight at its lower end. This globe of solid metal is calculated to compensate doubly the weight of the saloon with its complement of passengers. This might be taken, at a maximum, as cloven tons, and the counter-weight of twenty-two tons would then be ample to secure a free ac tion in accordance with the simple principle of gravitation. Nothing could be more nicely ac curate than the maintenance of a true level on a line with the earth in Mr. Walker's working model; nor is it easy, looking at the design ou this miniature scale, to detect any point so weak as to invalidate the entire project. The dimensions of the vessel on which it is pro posed to make the first trial of the new saloon are 190 feet length between perpendiculars, 20 feet breadth, 14 feet 3 inches depth of hold, and 824 tons burden. The number of passen gers accommodated on board will bo 150, that is, sixty-five in each saloon. These propor tions, however, may be increased or dimin ished; and it is claimed for the invention that, without loss of stowage, it is applicable to ships not only of all sizes but ot all descrip tions, and that it may be easily adapted to troopers. Ventilation is easily provided for by fans of novel construction; and, on the whole, Mr. Walker seems to have spared neither thought nor pains in perfecting his invention. " Kid Glove Maeino in Fbance. There are three departments in glove making in France cutting out, sowing, and finishing; that is to siy embroidering the back, making tbe button hole, and sotting ou the button. It is the work of men to cut out the glove; but women place it on tbe iron hand which forms the measure, strike it with a stamp, and pieparo it for the cutter. This is not difficult work; it is done by the piece, and they receive tenpenoe for five dozen. The sewers are less favored; the price Eaid for a rozen pairs of lady's gloves with one utton is 3. 9d.; out of this they had to pay fifty per cei't. to their employer, and foity per cent, goes iu silk, which they find; so that it only leaves about threepence-halfpenny a pair. If it be asked how many pair a good work woman can complete in one day, the answer will be that if working twelve hours without interruption, she may manage to get through four pair; but most of the hands only do two pair and a half. This arises from the atten tion they must pay to household work. Glove making requires the most perfect cleanliness; not only are soiled gloves returned to the sewer, but she is obliged to pay for the leather. Four pair will be thus paid at therateof eleven pence, from which a deduction muBt be made for lights of two and a half, leaving eightpence halfpenny. These wages are still lower in Avejron and Haute-Marne; but in the depart ment of Isere, tbis occupies no less than twelve thousand women, representing a value of six teen million francs. The manufactory at Gre noble omploys twelve hundred cutters-out, making five hundred and forty thousand dozen. Those who work the back of the glove and finish it off are better paid; seven-and-sixpence is given for a dozen, but then the silk is not iound. It requires sis or seven hours to make a pair of embroidered gloves; supposing she does a pair and a half a day, she will not earn that sum in a week. At this work a woman must sew regularly, and have neither children nor many household matters to distract her at tention, as it requires great nicety and skill. In Paris the work is done at tbe woikshop of the maker, where it can be better performed, and tbe highest cla-s of embroiderers obtain there about twelve- shillings a dozen. A Water Motor. At the Sutzbach Alteuwald colliery, near Saarbrucken, Prussia, machinery has been es tablished for tbe transmission ot power from a bteam engine at the surface, by a column of water circulating under pressure, the circum stances of the case not admitting of the estab lishment of a direct acting steam pump under ground. The mine is sunk 300 yards below the aurface, Tbe piston rod of the high pressure engine above is connected with the pressure plungers, each of which plungers is connected with the underground engine by a tubo filled with water. The last mentioned engine col- sists of four pressuro pumps arranged in pairs, and between each pair is placed the working plunger of one of Ihe mine pumps. When tho engine on the surface acts the power is trans mitted by one pressure pluuger through "one water tube to a pair of pressure pumps under ground, and thence to one working plunger, which either aspirates or forces air, according to its position. Tbe opposite pair of pumps and connections work conversely. The water is forced into an air vessel and thence through the rising main, 303 yards in hight, in one lift to the surface. Ou the change of stroke, the water in the cylinder of tbe pressure pump rise') iu the second water tube and follows tho retiring pressure plunger at the surface, the power supplied by tbe descent of water in one column being sufficient, with the exception of a slight allowance for friction, to effect its return in tbe other. If tbe cataract pauses of the en gine at the surface are not too long, the disj charge is practically continuous. The Engi neering ana Mining journal, from whose trans lation of the German description we condense the above, adds that at the Phoenix mine in Cornwall, England, an arrangement of similar description, consisting of a plunger attached to the main pumping engine, counected by a length of tube with a water pressure engine in another shaft, has been at work for ten years. Pibnot-Mautin Fijbnaos. It appears that the products of the Pernot-Marlin furnace are likely to give tise to a new nomenclature. This furnace turns ont what is almost a new metal, with a highly granular fracture, and tbe engi neers who have visited the Saint diamond works, distinguish between it and Bessemer metal without any hesitation. Is tbis metal wanting in homogeneity? Dose not tbe ques tion of the duration of the operation in tbe Martin process preponderate in attaining a good molecular arrangement? The operation seems to be performed rather too quickly with the Pernot-Marlin furnace, and, perhaps, if a minute analysis were made of the grains, the carbon would not be found distributed in sufficiently uniform manner? EnylUh Paper, Manufacture of Machine Paper-Hangings. The first process in machine-printing is pre paring tne ground of the pattern to the color or shade required. This is done by passing the paper through a machine which spreads over it an equal coating of color, by means of brushes moving transversely. As the paper comes off the machine it is quickly dried, by being drawn through a hot air chamber. All the paper is treated in this manner, except the) very lowest qualities, in which case it receives the required tint during the process of manu facture. The paper tor satin grounds is pre pared in a similar manner to that used for block papers, and polished afterwards by means of revolving brushes with French chalk. The printing machino contains a varying number of rollers or blocks, constructed of wood with a metal axle, and they print the pattern upon the paper. Great care and exactness are re quired in the preparation of these rollers, and a separate one is required for each color. The design having been traced upon them, it is raised on tho surface by driving slips of copper into the wood, and filling up with felt the por tions which are to make Ihe impression. In some patterns as many as twenty colors are used, requiring as many separate rollars. To print a flower, for example, several blocks are required, and in a design embracing various light shades and deep colors, each shade and color requires a corresponding roller. By changing the colors very different effects may be produced and various qualities of the same pattern are produced with the same set of rollers. Of course, every new pattern requires a fresh set of rollers, and a large sum is frequently ex I ended in produolng a novel design. Tho rollers or blocks are arranged in a circular form around the machine, which is about 10 feet in bight. Each roller having been supplied withits proper color from a corresponding trough, the paper is taken up by the machine in a continu ous web, or at least in pieces from 5,800 to G,000 yards in length. The, rollers press the paper against a large central cylinder, and as it moves along it receives the various colors in succession, and comes out with the design fully developed. Many of the colors are printed one on the other, but blending is preveuted by the ue of several varieties of size. There are ma chines for printing different numbers of colors; one with two rollers prints about 500 pieces in an hour according to the pattern; one with twolve rollers about 200 pieces; and one with twenty rollers about 100 pieces in an hour. A machino with two rollers produces tho printed paper at the rate of four miles an hour; and one with twelve rollers at about half the speed. Plain paper is produced from pulp at the rate of one mile au hour. The printed paper is marked off in twelvo yard lengths during the process of printing, and on leaving the ma chine it is dried by means of hot air. The rolling-up of the paper is also effected by ma chinery. Although machine paper hangings have been wonderfully improved during tho last twenty years, there isstill a widedifference between them and those printed by hand blocks. They are printed upon thinner paper, with less color on the prepared ground and in the formation of tho desigu. Machine paper hangings are, upon the average, about a third, and those in general use about half the price of those printed by hand labor. About three-fifths of the paper hangings sold are produced by machinery. They havo provided the cheapest possible means of giving a clean and cheerful aspect to all kinds of rooms, and are used by all olasses of the community. Toughened Glass. Tho invention of M. do la Bastie, by which he toughens glass by plunging it in an oil and tar bath, was, according to tbe Pittsburg Utrald, anticipated at the works of Bakowell, Pears & Co., as early as 1822. It was uBed to temper blown glass previous to its being cut. A largo kottle was filled with the ware, and fish oil poured over the whole till all the space was occupied. A fire was then put under the kettle and kept up till the highest attainable heat was secured. Then tho fire was allowed to die out and tho glass to cool gradually. In this way the object was effected, and there was no more trouble by the breaking of ware on the cutter's stone. In recent conversation on the subject with Professor Sweet, of Cornell University, he stated that bis brother, a manufacturer of springs in Syraouso, had succeeded in making glas very hard and strong by au oil bath used tor tempering his springs. The glass was so sirong that strips of from one to ono and n half inches in vldth, and of the thickness of ordi nary window glass, could not be broken by the hands. However, the slightest check upon Ihe surface with a diamond resulted in tne total disintegration of tbe glass, it being reduced to fine powder throughout its entire extent. It would appear that the statements that have been made relative to nicety in tho prepara tion of tho quantity of the different materials which form M. de la Bastie's bath have been consideribly exaggerated. The experiments at Bakewell, Pears & Co.'b works, and Mr. Sweet's experiments, indicate that oil is sufficient to bardi-n and strengthen the glass; but tho state ments made in regard to cutting thegluss, after tempering, at tbe Pittsburg works, du not agree with thoso made in regard to the breaking of the glass, resulting in its total destruction, and from tho slightest scratch. A piece of iron or steel, when broken, may bo again joined to gether, but the tempered glass, us far as yet discovered, can never be mended when once broken. This will, unless further improve ment is made, greatly limit its usefulnens. It is to bo hoped that further experiments may result in the production of a glass which, while it iB as hard as that produced by M. de la Bastie's method, will still be really tough. Eabtiiqdake Investiciationb. Father Ber telli, au Italian monk, tor several years past has made a study of the tremblings of the eattb, and more especially those which are so ex tremely slight as not to be perceptible save by fendulums placed in the fields of microscopes. u one year he recognized 5,600 of these move ments; and graphically representing the same over many years by a curve, ho finds that tbe line corresponds neither with the thermom etrio curve, nor with the tidal phenomena, nor can it be brought into relation with the distan ces or positions of tbe sun or moon. With tbe barometric enrve, however, it Is otherwise; and it appears that in the large majority of cases, the intensity of tbe movements augmented with tbe lowering of the barometrlo column as if (as tbe investigator states) the gaseous mat ters imprisoned in the superficial layers of tbe earth escaped more easily when the weight of atmosphere diminished, A New Method of Mabeino Tools . Much trouble can often be saved by marking tools with their owners' names, which can easily be done in the following manner: Coat the tools with a thin layer of wax or hard tallow, by first warming the steel and rubbing on the wax warm until it flows, and let it cool. When hard, mark the name through the wax with a graver, and apply nitrio acid; after a few mo menta wash off the acid, and wipe with a soft rag, when the letters will be etched into the steel.
