J. D. Manlove gives the “St. Louis Intelligencer” a description of a mountain of marble, which, he says, exists in the Great Salt Lake Valley. He says the marble is of' almost every color and shade, in slabs of very large area, and from an inch io thickness to blocks of an immense size. Mr. Manlove judges the marble to be of the best quality, and that it is inexhaustible.
