Several flowing oil wells have been struck one league from the coast, in the State o: Oaxaca, near Port Angel, Mexico, This strike has created quite on excitement in that part of the country. . John Wilson, of Salt Creek, Siskiyon County, last week retarned from a hunting tour in the mountains of Klamath, Trinity and Humboldt, bringing with him fifty odd deerskius and six hearskins. . A. company has been reclaiming Sherman Island, at the confinence of the Sacramento and San ‘Joaquin rivers, containing about 13,000 acres. The company levied a tax npon the whole land of over four dollarsan acre to meet the cust of reclamation, Two huudred Chinamen are at work, forming a broad embankment around the island, with a capacious draiu ditch inside. Tloodgates are being provided to relieve the ditches of water at low tide. Coan Mininc py Macminery.—At a recent meeting of the Institution of Mechani cal Engineers, Leeds, a paper was read by John Fernie in which the objects to be gained hy the application of machinery to coal cutting were stated to be: Ist, the cheapening of the work; 2d, the saving of a large quantity of coal, which, in the ordinary process of hoisting or undergoing hy hand lahor with the pick, is broken up inte slack and dust; 3d, the removal of the danger attendant upon undergoing by hand labor; 4th, the getting a larger quantity of coal out of the pit; 5th, in the case of machines worked hy compressed air, the collatcral advantage of better ventilation and a cooler atmosphere in the mine, owing ti the discharge of compressed air after each stroke of the tool The machine traverses — along the working face of the coal, and cuts out a horizontal slot or groove along the hottom of the seam of coal, or along a parting in the thickness of the seam itself. The work is at the rate of 8 yards to 12 yards per hour, including all stoppages, and undergoing the coal to the average depth of about 3 feet 4 inches in from the face. The work by each collicr by manual Irhor is ahout 6 yards per day of 8 hours, undergoing to a depth of 3 feet in from the face, The machine, therefore, performs,the work _ of from 12 to 18 men. . At Pittsburg, Pa., there is in operation a machine of this kind,{which goes either hy steam or man power. To PRESERVE SHINGLESAND FENCE Posts. In a paper recently read before the Farmers’ Club of the American Institute, J. B. Lyman says: ‘‘ In using many kinds of wood, and especially chestnut and sappy pine, for shingles, pickets, trellises, ete., much durability will be gained by boiling in lime-water, or a weak solution of carbonate of soda. ‘The boiling coagulates the most perishable parts, and the alkali corrects the acid of the sap, and prevents the growth of fungus. Whitewash is to be recommeuded as a yaluahle preservative of wood for a ‘similar reason. Fence posts should be well seasoned and then treated by hoiling the end to be set in the ground in tar or resin. Tor a foot each way from the snrface of the earth, when set, fence posts should be well coated with a paint that will exclude water. Setting posts top end down does increase their durrbility. Painting green wood is worse than useless. It promotes decay by shutting out the air which would stiffen the albumen beneath the surface.” Dynasure.—The Prnssiau Government have just concluded an extensive series of experiments with dyuamite, and next month the French Governmeut will follow suit. . The verdict given by the Prussian Military Commission regarding dynamite is, that 16 is at least equal in power to ten times its weight in guupowder, and that it is the safest blasting agent known.
