Storms for Inspector of State Prisons; and A. S. Johnson for Judge of the Court of Appeals.--In Maryland P. F. Thomas was nominated for Controller, James Murray for Commissioner of the Land Office, and T. R. Stewart for Lottery Commissioner, by the Democratic State Convention held on the 12th of September. A very severe storm swept over the whole southern coast of the United States and the West India Islands on the 18th of August. The damage to vessels and other property was very great. In the island of Porto Rico a great number of plantations and an immense number of cattle were destroyed, and many persons lost their lives. In the middle of West Florida, Georgia, and Alabama the gale was terribly destructive. The tobacco crop is said to have suffered severely. Advices from Texas give encouraging accounts of the cotton crop in that State. In both quality and quantity it will exceed that of ordinary years. A new military post has been established in the Clear Fork of the Brazos; and in the immediate vicinity, it is said, very large deposits of iron ore and of coal have been discovered. A very large trade in cattle has sprung up of late between Texas and New Orleans; the net proceeds of the trade this year are estimated at $120,000. The Boundary Commission is progressing slowly. When last heard from it was at the copper mines. The survey had been temporarily suspended, owing to an error in running the Boundary, making it 60 miles above El Paso, instead of 16, as required by the treaty. About 130 persons are attached to the American Commission, while the Mexican Commission has only seven. From El Paso we learn that a conflict occurred early in June between a considerable body of Apache Indians and a party of twelve Americans, on their way to California. The affray took place near the copper mines. The Americans were defeated, with a loss of two men killed and two wounded. Writers in the Texas papers, who have passed over the route to California from San Antonio and El Paso, state that it is far preferable to the usual route by way of Independence, Missouri. It is said to be shorter, cheaper, and less dangerous.
