Gunpowder for the South.
--We were yesterday on board the steamboat New Moon, and seeing a large lot of kettles, between twenty and thirty, some of great size, and the men at work getting a steam engine on board, we inquired what these articles were for, and were informed by the captain of the boat that they were intended for the manufacture of saltpetre at a spot in the mountains some sixty or seventy miles distant from Jacksonport, Ark., to which town the boat would convey them. We learned that Mr. Brinkley, of this city, and Mr. Jones, who resides down the river, opposite the town of Commerce, have bought from Capt. James Smith, who lives on Black River, the saltpetre cave about to be worked, at the price of $25,000. The purchasers, in the present contingency, have determined, patriotically, to spare no pains or expense to supply the South with an article she so much requires as saltpetre for the manufacture of gun powder.--As soon as thirty or forty hands can be obtained, they will be set to work, and it is believed that a large amount of saltpetre will be procured.-- Memphis Appeal, 14th.
