Thomas Scharf (1886)] According to the best of my recollection, there were twenty tivo persons constantly employed alsjiit the mine, sixteen of whom were considered the first-rate miners from Europe, all concur-ring iu the opinion that the mine was very rich. The mine was worked day and night to the last w ith great eagerness. j " James McCobd."

" I do hereby certify that I was personally acquainted with Albert A user, of the town of Mount Pleasant, deceused, and believe him to have been a man of truth and respectability. I have heard him speak frequently of the Sing Sing mine. He informed me he was the first person who discovered it. He found a piece of silver on the top of a rock, which he had cut out with a chisel. The mine w as worked for some years under the superintendence of Colonel James and he considered it as very' valuable.
