An Improved system of Illuminating the bowling alley has been devised by Gustavo llurkhardt, of Chicago, III., and as this game has recently become very popular, a description of his Invention In-vention will be of great Interest to the devote of this sport, which now comprises com-prises a great army. This Invention Is In the nature of an Improved appliance appli-ance for reflecting tho light and Indicating Indi-cating tho set of the pins, and It primarily pri-marily seeks to provide a reflector of an economical construction and In which the reflector walla nre so arranged arrang-ed relatively to the light that tho raye thereof can be positively concentrated concentrat-ed within a desired radius and the burner bur-ner held Invisible Thus, a blato of light Is shot around tho plna without making any shadows and without dax-illng dax-illng tho eyes of tbo player. Another feature of this Invention lies In pro-ildlng pro-ildlng a supplemental portion having a triangle or pin set face shapo, with light openings for numerals corresponding corres-ponding In number and arangement with the set ot the pins of tho alley, whereby the bowler can see how every pin Is numbered, id that when any pin Is not properly spotted he can readily call Iho number nnd have tho matter remedied by tho attendant Int.nilly ot Kanllattit. In order to measuro dlstauces, surfaces, sur-faces, volumes, time and force, standard stand-ard units were long ago found Indispensable, Indis-pensable, and this Is, ot course, absolutely abso-lutely so tn determining or measuring the quantity of light In any luminous body. Thla unit II the Intensity ot the light of the standard candle, whlcli li a sperm candle weighing one-sixth of a pound and burning 120 grains an hour. Ily this moans It Is found by astronomers as-tronomers that the Intensity ot the sunlight Is such that when tho iun li In the xenlth It Illuminates n white urfaco nbout CO.000 times ni strongly aa a standard candle at a dlatanco ot thlrty-nlno Inches. Comparing then sunlight with that of tho full moon, tho surprising result la arrived at that Iho former la nbout Cou.OOO times that ot tho latter. Again tho Interesting fact Is now established that of all tho different klndi of artificial light that con bo produced as yet by man, tho most Intenao Is the brilliant spot In tho so-named crater of an electric arc, but, datttlng ai It Is, It li but one-third as bright as tho turfaco ot tho sun Itself.

In Iceland horses aro shod wl'h sheep's horn; tn tho valley of tho upper up-per Oxui tho antlers of tho mountain deer nro used for tbo samo purpose; the shoes being fastened with horn pint; In tho Soudan tho hones aro hod with socks mado of camel' skin; In Australia horseshoes havo been tried of cowhide. A German not long ago Invented a horseshoo of paper, prepared by saturating with oil, turpentine tur-pentine and other Ingredients, Thin layer of such piper are glued to tho hoot till tho requisite thlckncaa la attained. at-tained. And tho shoes thus made aro durabls and Impenetrable to moisture. Ilrltril liy llcuilus Molar. II. Haddcn of tondon bai Invented a new motor cycle. The bars, which connect tho benxlna receiver and motor, mo-tor, also carry Ihe lighting apparatus, and tho bearers, which aro connected with the motor and back axle, carry the driving gear, comprising toothed srhecls, leather covered wheels, etc. Tho amall wheel la alwaya leather covered cov-ered aud tho large wheel metallic In order to secure quiet working. The driving gear Is constructed In audi a manucr that three different apeoda can be obtained. Tho machine.

A similar disaster disas-ter U reported from llombay, where for some year past two large Indian pythona bad occupied a rage In the museum of the llombay Natural History His-tory society. Thero was some mlaun-derstandlnf- between them over a pnrt- ridge, tor they were found so tightly entangled In each other's colls that tba utmost endeavors of peace-making keepers failed to effect a separation, and they were left to settle the matter according to their own lights Next day there was only one very stout python py-thon visible. These large reptiles evidently evi-dently know but one way ot settling a quarrel. In fJermany potato bread Is used by the natives of Thurlngla to feed thslr hemes, especially when they aro worked work-ed hard In iery cold weather. The animals an-imals thrive on It, nnd their health and strength are excellent. The method meth-od of preparation It simple and Inei-pemlve. Inei-pemlve. The potatoes are slowly slewed slew-ed till toft; they are then mashed thoroughly, thor-oughly, nnd an equal amount ot corn-meal corn-meal Is added. It Is mixed Into a thick paste with a small quantity ot salt. Tho paste li then divided Into four pound loaves and allowed to bake till thoroughly thor-oughly done. In the slow country ovens ov-ens It generally takes from eighteen tn twenty hours. When cold they arc fed to tbo horses and cattlo doing heavy work at Ihe rate of four loavea a day vlx: one In the morning, one at noon, ono at about 4 o'clock and one nt night. With tho last about ten pounds of poor bay are given. It ta claimed for this method that horses can do much moro work on the samo amount of food and that It Is good for their teeth. Mrs! Wlrs llarrcl Hoop. George M. Ucpow, of Canandalgua, N. Y proposes to displace the wooden barrel hoop by a spiral wire, for which ho has Just received a patent So greatly has grown the demand for barrels, many of which are shipped out of Iho country, that It has been found difficult to meet It, the chief source ot trouble being to secure the wooden hoops used for this purpose. The spiral spi-ral wire Is said to answer tho purpose faultlessly. It permits ot tho samo treatment at Ihe hands of tho cooper, and the spiral cxerti a tension which enables tho barrel lo withstand rough uajige to a greater degree than tho wooden hoops, Chlnrio l:iiimrora Muttrsl Clock. Ono of tho masterpieces ot musical clocki hai Just bem completed for tho emperor of China, In whoso palaco, bo sides pointing out tho correct time. It will play selections with a fully equipped automatic orchestra. It Is pronounced the most complete musical automaton In the world, having eight divisions, each of which has a rcpor-tolro rcpor-tolro of eight melodies. All oft tho plecei played by thli musical clock wero selected by the emperor himself, and consist of forty foreign and twenty-four Chinese recitals. Tho case ot the clock li mado of rosewood, lu Chippendale Chip-pendale antique style. Ilnrslsr Utile. One ot tho latest burglar devices la directed against the Intruder who wlshci to appropriate tho content! ot our safes. It Is to plate a grating In tho floor near the sate, and hldo under It an arrangement for heating water by electricity. When tho safe breaker steps on the coicrcd grating and ta to work there gradually rises a volume of steam, which soon makes him hurry off. |
