From the Philadelph a Pennsylvanian of this morning.
Late from the Mormons.
A friend has shown us letters of a late date from the pioneer camp of Mormon emigrants. They had at length reached the great salt lake, near which they had made a halt, and their wearied cattle were enjoying the sweet grass and fresh water with which that region is favored. They had made a new road from the Omata country to near the base of the mountains, which will no doubt be valuable to other emigrants from the Uni-ted States.
It keeps north of the Oregon trace, is said to be more direct than this, and is carried, by substantial bridges, over most of the principal streams which it meets. By the pioneers, it must have been traversed with difficulty, since they have evidently been subject-ed to great hardship. After leaving Grand Island, however, they had an abundant supply of buffalo beef, which greatly renewed the strength of those whose health was suffering by forced abstinence.
A single herd, with which they fell in, was estima-ted to number over 10,000, or, according to the calcu-lation of one letter writer, must have contained from 8 to 10,000,000 pounds of meat ; "a large supply " he says,"to be sent by quails in the desert." Should Whitney's railroad, or any Government works, be un-dertaken along the line from the Missouri to the Paci-fic, they will find their best contractors and workmen among the Mormons—hardy children of persecution—who appear to despise difficulty and danger.
