The following is the most recent information on the subject of these abandoned mines. It is from a MS. report by Mr. R. D. Oldham in Sirmur. Barthenole, Lat. 80 44'; Long. 77 46' 30."--Numerous old workings in limestone. Kunna In Jaunsar, Lat. 30 41' 30"; Long. 78" 4'.--Quartz vein in slates, of which 2 or 3 inches at the base are impregnated with galena and copper pyrites.

Galena was obtained, but it appeared to be sparsely distributed in a quartz, gangue being associated with iron and arsenical pyrites.

It is stated by Mr. Calvert (Ms.) that a sample of ore, apparently a mixture of galena and iron pyrites, on assay by Mr. Johnson, Assayer to the Mint, yielded 22 oz. 2 dwts. 12 grs. of silver and 2 dwts. and...
