Show 1 SCIENCE 1 Electrical and Steam Engines. The (Stimuli) government la encouraging encour-aging higher (prod upon Its rallwaya, and. to attain II, ban proposed a com-petition com-petition between electric ami steam locomotives. Hulldcra of both types bare been asked to submit plana Inr inotora whlrb will attain velocities of 100 miles per hour, but under what conditions, of load and permanent war baa not heeu elated. Tbe capacity capac-ity of our largest and most powerful locomotives, with 2o0 pounds of team pressure per square Inch and very moderate load behind the tender, ten-der, la limited to an average speed of from slity to sixty five miles per hour under fnvoratile conditions; It remains to bn shown what kind of a team driven engine can be produced which will rnlse the speed thirty five to forty mllea more tier hour. Electrle Water Heating Faucet. It Is an easy task to beat a kettle i of water oyer the elertrlo stove, hut .. - tbs Inventor le not aatlsfled with this, and must ncels go a atep further, enabling en-abling any ore to open a faucet and Warma the Water aa It Flows. 'draw hot water from a pipe connected directly with the city water supply, llow thla la accomplished can be anen by a little study of the drawing, which ahows the apparatus complete and rendy for use. The valve stem Is extended at the rear and connects directly with Die awltch which controls the elc;irlr current, cur-rent, so that when the Tim et la opened open-ed tho switch Is closed and vice versa. Ucneuth the fmic ct Is attnehed a easing, eas-ing, which rcseiii'des a tllter, but which Is In resllty a pair of electrodes, elec-trodes, between which (he watur must pass before It can flow to tho basin or bowl beneath. When tho current la turned Into theso electrodes, they bo-' bo-' come V) hot as to beat tho water passing between them, provided the llow Is not too rapid. The Illustration shows a amall beater for ordinary use, but there la no reaaon why the device cannot be enlarged to beat water for tho bath or washday. Where the . bouse la already fitted with eleclrlo - IlKhta It la a amall task to fit up tbe faucets for tbe new water heater, Harry M. Hill, of Bt Louis, Mo., la the Inventor. Paste Jar With Brush Moletener. If the bookkeeper of a balf century ago could look Into the modern office and bave eiplalned to him all the num-eroua num-eroua dovlrea wulch relieve tbe offlce man of to-day of a large portion of his work, the loose leaf ledger and card systems would no doubt be . shown aa the greatest Improvement since the old timer was In his prime; but thore are numerous minor lnven-, lnven-, lions which also fill Important places. Among these must be ranked the paetepot, which would much eooner bave taken Ita place could the paste have been prevented from molding and the brush from drying up as anon as eiposed to the atmosphere for a ahort time. Two or three Inventors have already produced pasta rocoptacles Hat Air Tight Cover and Water Compartment. Com-partment. which answer tMs prolile fairly well, but the Idia which wo suow seems to hrve special advartncs. In that a water compartment la provided for tho Immersion c;f the brush, and also , .' . mi air tlg'it cover for the Jnr Itself.

Omnha and Bcrnnton. Two of these. New Orleans and Omaha, are already committed to municipal ownership, own-ership, and for years there haa been a strung movement In that direction at Ban Francisco. Agitation to the same end was also very much In evidence evi-dence at Indianapolis and Denver a few years ago. A Transparent Mirror. Mr It l hard Wilson. New Yorlt, baa recently Invented a mirror which reflects re-flects Images or n transparent according accord-ing to the amount of HkIU In the background, back-ground, that Is. when tho background la darkened the glass is a perfect mirror mir-ror reflecting objects In" front of It, but when the background Is lighted one can readily see objects through the glasa. The inventor proposes to use the mirror for Illusive stage effects ef-fects or In show windows aa an advertising adver-tising medium. The darkened bark-ground bark-ground of the show window will be Illuminated at Intorvsls by automatic means acting upon an electric lamp, so that shoppers who stop at tho window win-dow to gate at their rnllectlon In the mirror will be surprised to havo their Images suddenly disappear, and see In tbolr stead the latest thing In I'arls fashions or the like. Disappearing Awnings for Stores. If tiiere la any one feature of a tore which detracts from Ita appearance appear-ance more than another It la the decoration dec-oration of the front with a dilapidated and faded awning. This may answer all purposes as far as keeping off tbe un and roll, but Ita condition la sure to prove a detriment to tho store. In some measure this baa been Improved Im-proved upon by the permanent metal awnings; yet these must render the Interior of the store dark and gloomy, and necessitate tho use of arUflclul light on cloudy dnys. Now, a compromise com-promise between the two Ideas litis madu Its appearance, nothing less than a metallic awning, which can be projected over the pavement or withdrawn with-drawn at will. In the Illustration Is presented a scctlonul view of a store front, with the awning partly projected pro-jected over tho pavement, allowing Slides Into the Building When Not In Use. the manner In which It le operated by the crank and gearing. A boiixontnl shaft extende across the face of the building, with gear wheels at cither end, meshing with racks on the awning awn-ing supports. The letter pass through openings In the front of the building between the first and second stories, with guides on the Inner aides of the walls to slide tbe supports 'nto the pare provided for Ihrm. The guides also eiirve to carry the weight of the awning when It Is projected, this being be-ing accomplished hy simply turning the crank, as is done In manipulating the cloth awnings now In use.
