Lewis Beck was a geologist at Rutgers University, and conducted a survey of the mineral resources of New York state in the 1830s. In this letter, he offers his thoughts on the qualities of a rock culled from a quarry in the town of Frankfort, Herkimer County, New York. He states that the rock belongs to a stratum esteemed for its qualities as a building material, and urges the letter's recipient, John L. Tillinghast of Albany, New York, to consult the Herkimer County geologist for more information.
