LATE NEWS FROM DESERET.—Advices from Salt Lake to June 6, state that the prospects of Breadstuffs in the Valley are quite gloomy, and that the grasshop-pers are destroying the crops to an alarming extent, causing the people to feel greatly discouraged. The nearest point where they can procure supplies is San Barnarding, 800 miles distant. It is feared there will be a great deal of suffering this winter, as the emigra-tion from the East, already on the road to the Lake, is very large. A party of twelve arrived at St. Louis on the 4th, on their way to the States. They came over the Northern route, having crossed the mountains in the latter part of April. They had fine weather du-ring the journey, and report fifty men on the road, and that six hundred to one thousand will return over the overland route this season. The eastern mail arrived on the 5th. There was no overland emigration on the route to California and Oregon.
