WINING AND SOTRENTIFIC-PRESS4). The principal mass of ore (a, ¢,) lies in the direction of the argillaceous slates of which the mountain is made up. At the depth of about 400 feet, it sends off a branch (6), which dips at a considerably less angle than thé slates themselves. ‘The greatest thickness of the mass of ore is over 150 feet; and its length is about 1900; but the dimensions decrease in depth, and at 800 feet its thickness is about 20, and its length 750 feet; so that there can be little doubt that the mass will terminate entirely at a certain not very great depth. The ores of this singular mass are chiedly sulphurets of iron, zinc, lead and copper, intimately blended together, and-almost entirely destitute of cangue. ‘The auriferous quartz veins of most gold regions belong to this class of deposits. They consist of belts of quartzose matter with sulphuret of iron, which near the surface is decomposed into a hydrated oxide, and contain gold disseminated through these substances, and sometimes in the adjoining rock, in fine particles, or, occasionally, large lumps. These belts ran with the strata and dip with them, and in other respects exhibit the phenomena of segregated rather than of fissure veins. . Practically, the most important feature of this class of deposits is that they cannot be depended on in depth as true veins ; as they seem almost always to be richest near the surface, and frequently terminate altogether at no very considerable depth. Nor is the ore or metal matter distributed — Section of the Ranimelsverg. through them with as much regularity as in the true veins, . . forming often a series of nests and pockets ranged in a general linear direction, and counected by mere threads of ore _or barren veinstone. Krvrr’s Cast Steen *Tyres.—Two of these tyres have been loaned to Mr. Krupp by the North London Railway Company, and are placed in the Exhibition, with his magnificent show of 100 tons of cast-steel cannon, axles, tyres, crank, intermediate and other shafts, together of the value of $90,000. ‘The tyres above referred to have run sixty-seven thousand miles, and do not yet require turning. 'The road is very severe upon tyres, and the engines are of the heayiest class, and continually under the brake, tho stoppages avcragiug about every mile. Here is an extract from a report made to the Board of Directors by their engineer, dated April 14, 1862: “The engines of this line run one million miles per annum, in round numbers, and this mileage performed by Krupp’s tyres would cost £733 6s. 8. while by the Low Moor tyres the cost would be £2,087 10s.” The average thickness of the tyres is 2.21 inches, and Krupp’s are caleulated to be worn down to one inch before they are discarded. To rn 189,539 miles will require one set of Krupp's tyres, four times turned, at a cost of £139, or six sets of Low Moor, twelve times turned, at a cost of £396, without making any allowance for the value of the old me: tal—which is greatly in favor of Krupp’s. The cost, therefore of running one thousand miles is 14s. 8d. by Krupp’s, and £2 Is. 9d. by Low Moor tyres, showing a saving of 65 per cent. It is a remarkable fact that the Belgian steel is even inferior to iron, showing clearly that the quality of Krupp’s steel, and not the mere fact of his tyres being steel at all; is the important consideration. —American Railutiy Review. GiRDS BUDDING KNIFE. Theaccompanying illustration, executed at this office, represents Mr. E. D. Girp’s Buppinc Kytes, a most inyaluable invention for the Pacific States. Mr. J. Silversmith, of San Francisco, has been authorized to dispose of the right for States, Territories and counties for the Pacific Coast only. This invention-is one of the many California has thus far produced, and is certainly deserving of her, it being the most useful and practicable for the purposes designed. The horticulturist who once adopts this knife will find its value so evident that ever after its services will be indispensable, since with it much labor and expense are saved. In speaking of it the Stientific_Americon says : “The above engraving illustrates a knife which is caleulated to facilitate materially the process of budding. Upon the ends of the blades are formed crescent-shaped ctosses of steel with fine edges for cutting the T-shaped slit in the bark of the tree to be budded. ‘These blades with their crosses are made of different sizes, so that some one of the three may be adapted to the size of the tree to be operated upon. “Tt is the practice of some horticulturists to remove the bit of wood which is cut from the scion with the bud, and to insert the bark only with the bud. To save this operation, the round blade is formed with several curves in its edge, so that it will cut the bark alone from the scion without taking off the bit of wood,'the curves heihg of different radii to
adapt them to scions of different sizes. , “ With this knife several operations are reduced to one, and the process of budding is greatly facilitated. The crescent-shaped cross is pressed through the bark. making the transyerse cut, and then by simply carrying the knife down, the vertical slit is made, and the bark is raised at the same time ready to receive the bud. ‘This knife was used in Galifornia during the last season, for budding several thousand trees, and it gave great satisfaction to the operators.” Those desiring to purchase will please address Julius Silversmith, San Francisco, respecting terms, &c.
