The Mono Diggings).—We were visited last week, by a number of miners from Mono Diggings, and have glcnned the following information:The new diggings were discovered about the 12th of July, and since that time, as we learn from the Recorder of that district, Mr. J. A Talbott, 1,200 claims, consisting of hill, gulch, flat, and quartz, have been taken up. The diggings so far as taken up consists of two gulches about two miles long, and about half a mile apart, with numerous cross ravines. The hills leading into these gulches have all proved to be rich, and the whole country is aEerfect net-work of quartz veins, six distinct veins aving been found to be very rich and traced a considerable distance. A distance of 45 miles, southeast, has been prospected, and gold found in considerable quantities, although water so far has been very scarce. There will not be more than .50 miners who will winter at the diggings, and many of these we fear will have to come away owing to tne scarcity of supplies at the mines—the winter having set in before a sufficiency could be procured. Three waterSwcr saw nulls are to be erected this w inter on the ast Fork of Walker’s river, two or three miles from the diggings, and town lots enough to form alarge city are already taken up, and many of themimproved, in the town of Mono, on Long Gulch. About twelve miles south-east from the mines, a large quartz vein was discovered by an old mountaineer named Hewitt, some 10 or 12 feet wide, that prospects splendidly, and a Spaniard brought in some valuable specimens of silver ore, in September last, who stated that he found a “mountain” of it sixty-five miles south-east of Mono diggings, and that ho was driven away by the Indians. An expedition has already been made up to leave with him in the spring to find the vein, and as he brought a large number of specimens, and is well known, no doubt is entertained of the truth of his story. About seven miles south of the mines is Mono Lake, which at this season of the year is covered with myriads of ducks, and the frugal hoard of the miner nas often been graced with a dainty morceau that would tickle the palate of an epicure. In the spring, the island in the midst of the lake is covered with eggs, and some seven miles west, in the mountains, there are some four or five lakes that abound with the most delicious trout, and occasionally a stray hunter brings in an antelope, deer, or mountain sheep to help eke out the miner's monotonous fare. There is not the slightest doubt that there will be more than f,000 persons at the Mono Diggings next spring.—Vlacervilk Observer,
