There are three shafts on the property ; No. 1, the mostnorthern, being 66 4 deep ; No. 2, the middle shaft shownin the figure, 61, and No. 3, or south shaft, 50 deep. The ore occurs disseminated through a chloritic slate (lowerPrimal ?) dipping conformably with foot and hanging wallabout S. 45° E. 70° to 80°. No. 2 shaft was put down all the way through these fer-riferous slates, and at the depth of 61 a drift was driven ^!ileportm. 355 Botterer Red Ore Section through Shaft ]Sfo. 2. Soale of Feet. 356 D.

This gangway was likewise driven north for 15, and fromthe top of a winze a counter gangway was driven in slates36 to strike isfo. 1 shaft. Between Nos. 2 and 3, and about 45 feet from the former,a cross cut was driven south-east through iron-bearing slates,44 feet long from foot waU, without reaching the top rock. The mine was again started in the late fall of 82, whenit was contemplated to carry No. 2 shaft down to a depthof 111 feet, at which depth it would probably strike footwall on a 70° dip. The foot wall has been explored for 75 feet along strikeof ore, which seems to be everywhere a rich argillaceousslate, high in alumina, but rather lean in iron, and carry-ing titanic acid.
