Four hand written letters regarding the Crown Mine in Quebec, just across the river from Maine. Some of the letters are datelined Portland, which was the nearest city of substance. The Crown was probably a small outlier to the Lower Canada and Hartford mines, discovered in 1865, which became the central figures years later when the group and surrounding mines (including the Crown) and prospects were sold to the Eustis family, who retained ownership past 1900. The Mine was well documented in a PhD thesis from MIT by John S. Stevenson, who performed the work on the recommendation of Waldemar Lindgren, unarguably one of the greatest mining geologists of the c1900 period. The author of some of the letters is Thomas Sheridan. The mine went on to primarily produce pyrite, and was one of the first providers to the US of pyrite for sulfuric acid.
