Show &cmveE. Gas Burner and Self Igniter. If a citizen of ancient Home could have tho opportunity to light tho gas with ono of thoso convenient Uttlo electric lgtittcrs, without having nny knowlcdGovof tho origin and nctlon of tho gas Itself or of tho electricity, It Is safe to say ho would bo moro surprised than at somo of tho so called miracles which the alchemist and charlatan cf Ms dny produced. Tho gas humor and 6olf Igniting devlco which wo Bhow In I 111 i Turning on the Gas Starts the Flame. BfL- tho plcturo havo been designed for uso WW whoro tho light can not bo placed j' within easy reach of tho hand to opor- I ato tho sparking wires which light tho I gas. With this appartus it Is only I necessary to open tho valvo In the I pipe, permitting tho gas to flow Into I tho burner. Tho latter comprises a I teal chamber and a diaphragm, togeth- er with an electric igniter of tho ordl-I ordl-I nary pattern. A Uttlo study of tho drawing will show that when the gas I pressuro Is turned on tho diaphragm I must expand in tho seal chamber, and I this expansion Is utilized to manlpu-I manlpu-I late tho Igniter, by concctlng tho dla-I dla-I phragm to tho pivoted arm which car-I car-I rles tho sparking wire. Upon closing I tho rnlvo tho diaphragm falls of Its own wolght and tho Igniter onco moro I ndjusts itself ready to produco the I spark whon tho prossuro Is applied I again. Tho inventor Is Charles T. I Willson of Amonla, N. Y. I Milliner's Hat Holder. I Men havo for some years past had tho temerity to hang out their signs ns I makers of ladles' suits and costumes, I but tho man milliner is as yet a scarco I article, and liable to bo so for somo I time to come. Possibly tho Invention I we show hero might havo been de- I signed by a man milliner, If thoro had I been moro of them In tho business, but I as It Is, tho Idea originated with a I woman, and Is likely to bo used almost I exclusively by women. Tho. Invention I comprises a number of clamps and a HJk pair of telescoping rods, with a trlan- IE gular support for tho hat at ono end BM, and a scrow clamp at tho dpposlto end, H which can ho attached to a table, shelf I or chair. Tho hat support consists of I threo projecting wires, and by sliding H JUCIUTATE3 TUB PROCESS OF TIU31 MINO.

Sarah S. Torrcnco of Chicago Is the Inventor. i . I Producing Arsenic by the Ton. L. When tho statement is mado that Py during last year Canada produced 725 W tons of arsenic ono is apt to wonder ' whero It nil comos from. A mining Journal Ir authority for tho statement I that It wns all oxtractod from gold I ores with tho bromoeyanogon procoss. I After tho contcntrate3 havo been freed 1 of tholr gold contents, tho remaining I matter Is passed through a cylindrical I washer, nnd tho nrscnlcal fumes riro I condensed In sultnblo chnmbers. Af- I tor passing through a refining process I and being again condensed and col I lected In a second sot of chambers, tho I resulting product Is stated to bo over I 99 per cent of arsenic of a puro whllo H color. I Abundant Underground Waters. I Tho oarth contains nn abundanco of H water, oven In places Ilka samo of our I great western plntcaus; whero tho sur- H faco Is comparatively arid, says tho Mining World. Tho greatest depth H at which underground wator can oxlst H Is estimated to bo about six miles. B low that, It Is bclloved, tho cavities H and pores of tho rock nro completely H closed. Tho amount of wator In tho H earth's crust Is reckoned at nearly one- third of that contained In tho oceans, H so that It would cover tho wholo sur-H sur-H faco of tho globo to a depth of from 8,000 to .1,600 foet.

An Ingenious Invention. Tho Il6ppo",Auto Pedal Is tho namo given to tn Ingenious Invention which has Just hosn placed on the market by C. J. Hoppq & Son, piano makers, in this city. Its purpoto Is to correct tho Injudicious uco of tho forte, or loud pedal, In a piano. Whon used with tho Pianola or other piano playing play-ing , attachments, tho Hoppd Auto Pedal controls tho pedal of tho piano liko an artist, and does It automatically, automatical-ly, thus permitting tho porformor to fully enjoy the music with no tax on his ml ml as to this portion of tho playing. It gives tho correct so3tenuto effect automatically, without requiring perforated music to ho cut especially for It, and can bo attached to any piano player without changing original origin-al construction. Tho Invention wa3 concelvod and planned by Florenco J. Hcppo. and was developed nnd constructed con-structed by Philip Wuest, Jr., superintendent super-intendent of tho Heppo mechanical department. de-partment. Philadelphia Ledfor. Vest Pocket Punching Bag. If everybody would uso faithfully tho exorcising apparatus which tho Inventors Inven-tors havo produced, what a race of athloto3 wo should nil becomo In n few 'years! But somo havo ono excuso and somo another, nnd somo mnlto no excuso ex-cuso at nil, for neglecting to train I ft) Inflated Ball and Clastic Cord. tholr muscles and develop their bodies to that slato of perfection which wo often dream of but seldom attain. Perhaps Per-haps tho mos't plauslblo excuso for this neglect of physical training Is tho lack of time to go whero tho apparatus for tho work may bo found, but this excuse ex-cuse can not avail to Justify ontlro omission of exerclso In tho future, for nn, apparatus has boon Invented which can be folded up and carried In tho vest pocket. It consists of a thin rubber rub-ber bag, with an elastic cord connecting connect-ing It with a band passing around tho fingers, and Is used practically tho samo as tho punching hag, tho alertness alert-ness and swiftness of movement required re-quired to strike tho bag making up for tho lack of actual muscular exortlon. While tho bag is small enough when deflated to bo storod In tho vest pocket It Is fully eight Inches In diameter whon filled with air, whllo Its lightness light-ness necessitates the employment of no Inconsiderable amount of Flclll and accuracy to drive It' from tho hand oven n fow times without missing a blow. Either ono or both hands may bo used In tho exerclso, and to vary tho speed of tho return It Is only necessary to chango tho length of tho elastic cord which connects it with tho finger loops. David J. Wilson of Wash-ington, Wash-ington, D. C, Is tho Invontor. Marvelous Liquid. An engineer of Munich, Max Ebor- I hardt, gavo recently a demonstration of tho effectiveness of a now prcpara-, tlon for extinguishing Arcs. Tho trials, It Is roported, were successful. Tho preparation Is a liquid of a milky color. ' Tha flrst exporlmont showed thnt tho skin, when painted with tho liquid, becomes InEorslblo to heat. Rags saturated with petroleum can ' bo burned upon tho hand after It ha3 been lmmersod in tho liquid. Small fires can bo oxtlcgubihed with tho hands, and with ono pailful of tho liquid a flro In n pit cf tar was put out In ono socond. Tho tnr, oven after petroleum had boon poured over It, could not again bo Ignited, as tho liquid formod a thin, unmeltablo rru-.t which completely extinguished In twclvo seconds with n Uttlo moro th. twolvo gallons of tho liquid, vj i 1 quantities of tho preparation aro, am-cient am-cient for extlrgulshlng purposes, ro that tho damages produced by wator aro avoided. Tho price of tho liquid Is about 7G cents por quart. A New Method of Making Casts of Fish. Ono of tho latest outgrowths of tho wonderful art of olectroplatlng Is tho uso of tho "galvano-olectrlcal method" In taxldormy In making casts of flshes, roptllcs, birds and animals. Tho Smithsonian taxidermists woro among tho flrst to adopt this now mothod. It has been the experience In sending send-ing about plastor and paplor-mncho casts t,f nnlmals to various oxposltlons that they nro subject to much damage In packing nnd shipping. Instead of fragllo objects of tbla kind, theroforo, persons will seo arlmals of hollow copper nnd brass, so lifelike, howover, that many will think that tho real thing Is before them. |
