An old and long abandoned chromite mine located 1 mile west of Etchison Post Office, in the northern tip of Montgomery County, Maryland, is interesting mineralogically, as having furnished the fuchsite and chromium-bearing tourmaline described by Gill.2 This locality was visited by the writer in November, 1923, in company with Messrs. W. F. Foshag, Edward Sampson, and Waldemar T. Schaller. No difficulty was experienced in locating the old mine and a search of the dumps resulted in the finding of a few typical specimens of chromiferous tourmaline and some especially good specimens of fuchsite.
