Provenance:

Harlan Page Gage (1843-1890) was a Hopkinton resident who taught in Boston. Another item related to Harlan Page Gage (gavel) was given by his daughter, Eliza M. Gage Reycroft; possibly this item was also given by Eliza Reycroft, most likely after her father's death. From its beginnings through he end of the 19th century, the Antiquarian Society actively collected samples of minerals and oddities. This object is an exellent example of a "septarian concretion", which is a mineral deposit that formed around some small object-like a leaf or a snail- and then went through a phase of shrinkage, creating cracks which then filled with crystalline cement, such as calcite or silica. The resulting crack pattern often resembles a turtle shell. This one is marked, "Onondaga Lake H.P. GAGE" Onondaga lake is located northwest of Syracuse, New York; the collector of this curiosity was Harlan Page Gage (1843-1890) of Hopkinton.
