There were U implemente on exhibition, but only four o' them were tried, and of theee only one worked terfeotly. The "General Sherman," a email leech-loading cannon, whioh wae expected to tire 26 ehote per minute, tired 20 thota in a min ute and a half. The "Vixen," built of bronie, tired a one-inch ball onoe in seven seconds. The "Annihilator," whioh wae intended to tire two charge in a eeoond, fired one in a little leaa than two eeoond. The "Lady McLean," whioh ha 36 barrel with an estimated capacity of nearly 13,000 ihot per minute, with a range of three mile, waa worked to the apeed of 72 (bote per eeoond. ' The other gun were not in order for trial. Among other invention that Dr. McLean exhibited 1 a magnetic torpedo pro pelled bv clock-work, and guided to iron thip to be destroyed by a load it one. The gune were pronounoed fairly luooeeiful by the ottt oert, but the olaim that they would bring on a millennium waa by no meane admitted.

L'lleureux, which reet upon the jute in the manufacture of o-oallod Wilton or Brunei carpeting, which hitherto hu been made from wool The appli cation of Jut for thi purpoee i facilitated by the preparation of a portion of jut yarn into what ia called the "Camel," and by the vary ing proportion of the number of the yarn nude nee of for the web and the main warp. The lute yarn ia fermented for about 10 or 12 honra in aaolution formed of SO quart of water and one lb. of alum, theee proportion to be uaed for work ing about 90 lb. weight of thread. After the Jut ba tbu been cleared of the oil it may hare gathered during it progree through the vari oua processes 01 the (pinning mill, that ia to ay, after it ba been disiofeoted, it i dyed If required in the ordinary way) the Jute ia then lied with the following preparation, one lb. of itaroh diaeolred in 00 quart of watery the aame weight of Jute i tubnutted to the weight of til ing above-named.

MIKES OF S0N0RA, MEXICO. Th mine of Bonora hav been worked from time immemorial. Tle (tuuieue number of old mine that hav a history clouded with early tradition prove th ancient character of the mine of Sooore. Some hav been known to reach back 100 yean, and other hav no data to determine the first period in their history. The number of abandoned mine la consider able, some of whioh were unquestionably x hsusted, while othsr wsr abandoned 00 ao oount of the igooranoe of the miner on reach ing oree that were refractory or hard to work. Right her it might be well to oaution Ameri can capitalist againat buying hole in th ground, tolely because, at one period is their history, they had yielded millions. Moat of the abandoned mine, or quit a large number of them, and of th richest, have been ruined by th olaaa of minere of Mexioo called "gambuoinoa," a poor olaa who had so capital, and were in search of "booanaaa," or rich spot, working tbeee eolely, and tilling th drift and shaft behind them with rejected ore and rubbish, eo that when they finished a mln it was almost entirely ruined. In aom inatanoee, they hav extracted th pillar of old mine of great value, and the walla have fallen in, thue doing an Incalculable injury to the mine of th Hut. Then is an old Span ish proverb that tersely eUteei "It take an other mine to work a mine," Tbie ia undoubtedly true of very mln aban doned by theee miner. We uee strong language on aooount of the destruction following in the weke of the "gembuoinoe." The warning of Mr. Mowry to capitalists in his valuable work on Ariion and Bonora, w herewith quote 1 "A it is desirabl that, in the investment of foreign capital there ehould be so error com mitted at the outset, than whioh nothing would retard the progree of thi new mining Held more; all persons new to the oountry had better leave abandoned mines alone, nnlese directed to thrnt by pirsoos long reoideot is the oountry, whoeo character and veracity are undoubted, and who, after the In recitation of all the faots, current aooounta, and traditions, hav full eon flilsoos in torn abandoned mln or other. There sra, undoubtedly, many abandoned mine that ar well worthy of attention and outlay of capital, but stranger are not likely to know at once which of th many deeerted mince it will be prudent to meddle with. Under the ftreeent itat of things, the aafeet Inveetment or new oomere will be thoee mine that hav bona fid owners, for, a long as a mln can be worked according to th custom of th oountry, it I hardly svsr abandoned altogether. The owner are fully alive to th value of their possessions, and aa they ar already Is more or leee independent position, and alweya In ex pectation of a sudden fortune, they ar sot an 1 ions to tell unlee induoed by fair offer. It ia not advisable to enter Into any arrangement with Mexioaa minere to furnish oapital to open np a mine, but it I better to boy th whol at once." PnoerHOR Tin.

DETECTING OAS LEAKS. Mr. G. F.

The action of Mr. Ausell't Or, damp Indicator I founded on th faot that dif ferent gaaaee hav different rate of d' (fusion through a porous body, th velooitle of difltt. eion being iuvereely ae th square root of th respective densities of the gasea. la th gaa. leak indicator thi property is takso advantage of a follow!
