New Use Of Air

It is bnrdly best, in these days, to asHurt tbat any industrial operattou; however diffioult, caiinot be performcd bj machinery ; or any meobanical problenj, oo matter how nemly impossible, candot be solved by nventors. There is an old story that the statement was onee confidently made that no carriage oould run without wheels, whereupon som genius conetructed one to run upon legs. lie would doubtless have had lees easy work to have answered the query of how the Lides of dead oattle oould be removed more quickly and with less damage than by the usual prooess with the knife. We fiud, however, that the answer is to be given on the "pampas" of Buenos Ayres, ia South America, wbere cattla are killed by the thousand ior the Indc9 alone, and from wbence our tanners draw no small peroentage of their mate rial. The plan proposed is eimply to foroe air between the flesh and the skin of the slain animal by nieans of a pump and suitable adjunct, and it is said to require only a minute or bo to wholly dotaoh the liido. Tho idea is plausible ot.oujjh, and, if tbere are no practical olgtacles, it ought to afford a veiy lrge eronomy of labor and time as oompared with the ordinary racthod of performing the same work. No ioformation as to the precise oouftruction of tbeapparatus employed is at hand; but any ingenious meohauic, with the general principio laid belore hitn, sbould be able to devise méans fur oarrying the suma iuto praotiuo. If tbis sliould prove suecessful, the adoption of the plan in ihe abbatnirs of oar largo cities would uoon pay a heavy profit on all the oosts of experiment and iuln ductioo to praotical use.
