One day, while hunting minerals near the town of Hillburn, N.Y. (near the New York-New Jersey border) I came across a large boulder composed mainly of phlogopite and graphite in quartz, which had been blasted out of the hillside for a road.  The thing about this particular boulder which attracted my attention was the occurrence of a cavity in the top, about ten inches long and seven inches wide, and filled with a gray-black powder about the consistency of slightly moistened powdered chalk, being easily broken up with the fingers.  I had noticed this same substance in minute amounts imbedded between feldspar crystals and closely associated with pyrrhotite in nearby rocks, but thought it to be merely dirt.  Upon testing a little with borax, it took fire, and burned almost clean with a blue flame, little smoke and a strong “sulphur” smell.  It proved, without doubt, upon further examination, to be sulphur.  It was verified also by Dr. Samuel G. Gordon, at the Academy of Natural Sciences, Philadelphia.
Its occurrence in the boulder was probably due to the alteration of  pyrrhotite, magnetic iron sulphide, with sulphur formed as a by-product.  This is further proven by its usual occurrence with this mineral (a little platy pyrrhotite was found deeper down in the sulphur).
At this same locality there are many interesting minerals, among them the following: Graphite (in large flakes and crystals); Coccolite (abundant); Augite (good crystals, large cleavages, etc.); Molybdenite; Phlogopite; Pyrrhotite; Apatite; etc.
