WORLD-WIDE NOTES.

iV DINARY. : \;" ; ' -" The efficiency that ba| : , been reachr" ed in appliance for .asfiWng factory •'ismoke was lately illiiistritted in an *•' exhibition of a Johnscin ramoke consumer that has been? 'in use two 0 'years. The apparatus Is essontially [ y an extra grate of perforated ashesB " tos and fireclay bric.ta, which k s > built behind the ordinary, grate, and '• I is proportioned to give* an intensf 19 temperature to the air'; required for )J perfect combustion. Instiiad of passis ing into the boiler flues, the mixture '• !of smoke and unconsumed! gases, :re!r. tarded by' the. second gra. te, ignites, ir and burns with the addition of much n heat. There are no steal n Juts,'the r " working is "automatic, efld a<:ony venicnt tever turns, the grate' op. 01 lG off. Besides the -preventing of smoke 16 a considerable advaritago is cl'atmed '" in the saving of 'rail, in the" test IV 'made, a great clo«d of smoke from J fresh fuel was sent into the chimney; 1 j then the apparatus was applied, and e within forty scaonds-the time'need0' ed for the flues to clear—every trace iU :'of smoke had vanished); from the D . chimney's mouth. ■'■ d I ; fc COLOURED MOVING ftCTTJRIBS »" REALLY. COMING. " Tlie solution of,the problem of colD oureil moving pictures 1b claimed by Bcrthon, a French experimenter. The t natural tints are split up into three t primary, colourE-blue-violct, green, , and orange—by three narrow colourJj ed slits in the lens o( the camera, and 'the images of' these slits, in i complementary colours, are repro- ! duced over the ordinary photograpMo i image on the sensatlvc. plate by an j interposed special screen,. consisting of a great number of: vdry narrow s ; curved strips of celluloid. The result is a photograph of ordinary appearance. This, however, is thrown ) on a screen' through a tens with three coloured slits similar to that used for taking the pictures, and the ' t i original is reproduced in natural colouring. 5 THE FROG INDUSTRY OF FRANCE. ' y . That the frog industry of France D is a business of considerable magnir tude may bo gleaned, from the fact that the annual production is now t close t 0 50,000,000 frogs, all of which n are consumed within the country, s with the exception of tho export to e England. Great ponds are v alive witl . tho jumping animals, and the catch; r which is made'in the night, is a pic a turcsque sight. Long; lines of flam--3 ing faggots, soaked 'in tar and car- ,_ ried by small boys, catch the attenj tign of frogs in the midst of theii | nightly ■musical entertainments, and j they jump towards the fatal flare. 3 Men with,' nets follow the faggot B bearers and catch as many as 25 or T , 30' fascinated frogs in one swing of _ I the net. The legs, or saddles, are j- 1 served in omelettes, fricasseed ir , butter, fried in bread crumbs with a . | white sauce, grilled, prepared with 1 j beaten eggs, and in many other in- - 3; viting ways. Magnificently "fatten- . Ed" legs soil for about 6/ per dozen. [ | A meat pie of frog's legs -and truf- ! fles, ordered to celebrate an excepj tional run of luck at Monte Carlo, cost the plunger a little matter oi ■ £24. I PARIS BUILT OVER YAWNING j CHASMS. j A strange fact has been made pub* ; lie in connection with the awful e floods in Paris. It seems that tho ! i quarries of Paris, many of which I I have existed under the city for cen- .', turics, little known even by Parisg'ians themselves, proved an agency [' which caused much of the destruction. Into these yawning chasms [ I flowed countless, tons of water, rush[jing in angry torrentß through the ■ eight hundred miles of galleries, and i tearing away walls which supported public buildings and private houses, .' During the height of the flood great ! holes appeared' in the streets, and , pavements dropped out of sight. In some places these great excavations, from which millions of tons of stone ' have been taken in the past, are two stories deep, Only 'a 'few months ago one of the streets in the Montmartre quarter fell into one of them, and several persons were killed. Of late years tha municipal engineers have been attempting to locate the dangerous places and take measures to prevent such accidents. Thero are, however, many great excavations yet undiscovered. CLOTH OF ALUMINIUM. Though aluminium takes first rank among metals for lightness combined with toughness and durability, it is hardly what one would expect to prove useful as a textile ma- ! terial, but the articles now made from it include scarves, shoes, belts, neckties, shawls, and hats. Straps and lacings for boots are among the newest productions. Sieves or screens made of aluminium have proved especially valuable in sugar refining, as it quickly becomes coated with acid resisting oxide.; and it can, be woven alone into fabric for other purposes. The best results, 1 however, - are obtained by employing tho aluminium yarn-smooth or twisted—as warp, with coloured silk threads for weft. When this cloth is made into cloaks or theatrical costumes, the effect is very striking, and the body of a beautiful woman is 'said to look as though dipped in silver.
