THE WEST SHORE. February, 1880. 48 ARTIFICIAL OEMS, Dr. Percy write to the Ixmdon Tinm with regard to Mr. Maclean' alleged discovery : "1 agroo with Mr. Maskelyno in thinking there in reason to expect that the diamond will some dav he artifieiallv produced.

Alumina, tho substance of aapphire anil ruby, ha long hcuu crystab lised, yet to thia day no artificial aapphire or ruhy worth a farthing haa appeared in the market.

At a recent meeting of tho GlaK"w l'hiloaophieal Society, Kl. John Vincent Day road a communication from Mr. Kolicrt Has. tor, of Dundee, regarding the production of artilicial diamonda. Mr. Haxtor began to experiment in IH7(, but did not obtain auccoaaful reaulta till April, 1.H77, when pure cryatal of carbon were produced. The cryatal then obtained were all L't through careleaa handling. Mr. Ilaxter endeavored to procure more, but for aovoral month did not lucoeod. Hi cryital had been tested 'ii a manner leaving no doubt about their genuiuenoaa. He had tried without aucceaa to produce largo cryatala, hut eaw no reaaon to preveut their ultimate production.

Paper-hanging in quite a modern invention, after all; that i, in its Western use. In the East wall-papers had been known from time immemorial; but it was only toward the end of tlie neveuteeiith century that tliey Were brought from China, imported into England anil Hol land along with a multitude of other inilionnes and chinoiseries. Francs took hold of tho idea and perfected it, and haa hitherto produced the lKt, while Germany and Belgium have given the cheapeat papers; hut England has lately come to rival Franco. Thero is now a vast variety to choose from everywhere; mounting from the rough kitchen fourpenny paper that, put 00 wrong aide out, when its pattern is but slightly stamped, present! a uniform gray sur face like something a great deal moro expen sive, and where the pattern is heavily stamped, presents a damascened gray surfaco, to those elaborate in art and material, whoso use in a single room requires nn expenditure of a small fortune. There are the common satin-faced ones, the gilded, silvered and bronzed grounds, embossed gilt and mica, imitation of Bilks and tapestries, cretonnes and chintzes, raised and stamped velveta; there are some like delicate muslins embroidered in chain stitch and lined with color, at six dollars a roll and upwards; others like the dark, old, embossed Spanish leathers but toned to the wall, from nine to twelve dollars a roll, according to present prices; thero are the thick, Japanese papers, where the black ground riots in fantastic assemblage of all rich colors, where a cold ground carries birds and butter Hies ami fans ill charming profusion, and those of lighter, less marked and less agreeable char acteristics, at about the same prico as the leather papers; other yet more expensive, thick ami heavy, a linoly-glaz.cd porcolain-like representation of lilea of all sorts, for those who will have them in imitation; and in addi tion there are the frescoed papers, and thoso for ceilings, for dadoes and for fricz.es. It would he hard if out of such a variety ono could not get up rooms that would bo satisfying to the moat demanding sense of tho beautiful. K n.i.kh BY A Murrain. As David Meisen thalor, tho well-known stockman of Whitestono township, was driving hi cows to the barn about daylight this morning, he was atruck by an aerolite and instantly killed. ItappcarBas if the meteor had come from a direction a littlo wct of South, and fell from an angle of about IK) degree, for it lirst passed through a tall maple, cutting tho limbs as clean as if it had bcon a cannon hall, and then struck him appa rently on or under the shoulder, passing clean through him obliquely from below the right shoulder to above the left hip, and buried itaclf about two fast in the soft black ground. The poor man' head and legs were uninjuicil, but the greater part of his body HUM to have been cruahed into tho oarth be neath the terrilic aerolite, which is about the ai.e of a common patent bucket, and apparently of a rough round ahaie.

Gorman telegraph engineer have lately I wen experi menting with aluminium aa a material for tele graph w ire. Thii meUl caii easily tw drawn out to a very much liner gauge than ia Mtiblo with iron, and its oouduotibility is twice as great aa that of iron wire. Its excessive cost has hitherto prevented its use for tho purpe indicated, but it i found that an alloy of alu minium and iron can eaaily be made, which will produce a wire both finer and trongcr, and less uaceptihlo to atmoaphcric changes than iron wire, while it is much Uerior as a conduct ing medium. MAGNITUDE OF LABOR. There is nothing that has ever attained the vast proportions that labor has acquired. It extends over the entire globe, so far as the operations of man arc concerned, and through out the seemingly unlimited realms of space, under the exertion of the Omnipotent Creator. Leaving out of consideration the wondrous array of stellar systems, and narrowing the view to the work of the human race, tho field is still too ample for a detailed narration. It can, even in this scope only, be treated of in generalities, The animals labor, but it is only to the extent of self-preservation. Tho beaver builds his dam across tho running stream; tho birds construct their nests in the branches of tho trees; the burrowing animals dig into the surfaoe of the earth; and the insects spin their webs or con struct their fragile cells each and all guided by the natural law of permeation of their progeny. The labors of man extend to a higher and nobler plane. Originating in self-preservation and protection of offspring, they have risen to the moro elevated rank of a creative power, which has encompassed the earth and left no spot upon its surface undisturbed by their mul tifarious results. In every phase of social life labor holds the sole sustaining Influence, deprived of which tho fabric of society would meet with annihilation, and man descend to a scale below the heaver and the bird in practical utility. In the ad vancement of tho well-being of the human race, labor has ever been tho motive force which has accelerated its progress. It has stimulated the intellect, and conferred aptness upon muscular manipulations. It has given ideas to the brain, and deftness to the hand. Its results have pointed out new methods of attaining them, which havo required less muscular action and more brief periods of time, with greatly in creased results. Nothing can be effected without labor; with it, all things can bo accomplished. When in operation, it is vitality; when inactive, it be comes inertia and death. It crosses continents in its gigantic strides, steps over oceans and traverses tho globe, carrying with it beneficial results, and imparting as it goeB, ardent desires for a continuing increase of its blessings. It points out the track of the seemingly erratic comets; it maps out the path of the sun, moon and stars; it measures tho far-distant worlds, and weighs them with positive accuraoy. It has constructed instruments by which their constituent forms of matter are made known. It overleaps the confines of tho earth, and ex tends its efforts to tho remotest regions of stellar existence. It razes mountains to the level of the plain, or cuts its passage through miles of their base. It deepens rivers, tills up lakes, makes fertile the dosort. Earth is but ono of tho compartments of its workshop, and in every section of that compartment it demands and compels activity. Its avocations aro unlimited, extending from tho least to tho grentest productions, from the sharpest point of a needle to tho massive form of the pyramid; operating upon the formations of bodies almost too fragile to be touched, and working upon others of adamantine durability. It is a magnificent tcmplo of God-like propor tions, so vast, so extended that it embraces tho w holo realm of creation; so perfect in its con struction that defects are unknown; 10 endur ing in its material, that it will still exist when earth shall havo passed away; so wisely planned that beauty and harmony are presented at every point, and its resultant will bo the advanced welfare of man. Omniscienco only oould have invested labor with its grandeur and greatness, and have stored it so fully with benefits and blowing!. Its dome riioi to the highest heeveni and 11 lighted by the itsri; its walli contain all created matter, and its foundations rest upon unswerving utility. Into thii vast hall all must enter and perform their task, which to aomo will lw hard to accomplish, to others, easy of performance. There is no exemption from this duty. M inimjand Sdtntific Press.
