From the noted collection of William Drown who, according to the Mineralogical Record Archive on him, was an umbrella manufacturer who used his fortune to amass a collection of some 6000 mineral specimens. His collection was kept by his family for a generation after his death and then donated in 1918. Ex. Philadelphia Academy of Sciences Collection.

MD-225235 - Antigorite - - Archived Tilly Foster mine, Brewster, Putnam Co., New York, USA small cabinet, 6.8 x 4.4 x 2.7 cm. CLICK HERE FOR LARGER IMAGE: 6.8 x 4.4 x 2.7 cm. This is a surprisingly attractive specimen of a rare serpentine group species called Antigorite, from the old Tilly Foster Mine. According to MINDAT: Large iron ore (magnetite) deposit discovered in 1810. The mine was 600 feet deep in 1879. Mining ceased in 1897, after 13 miners were killed in a rockslide. Usually, you get chondrodite and a few other species like clinochlore as mere associations. However, here it is definitely not common to get a good specimen of one of the rock-formers like this serpentine group species that is actually a "specimen" and not a "rock". This is a really interesting, showy, crystallized piece, with a distinct curvature to the crystals and to the specimen overall. Ex. Ken Hollman Collection.

Specimens today are obviously hard to come by, and I know people who are dedicated to collecting Tilly material.
