Keys to History

This herbarium press was used by the McCord family in the 19th century to dry plants. John Samuel McCord (1801-1865) was an accomplished amateur scientist and an avid gardener, which no doubt accounts for his use of this press.

Herbarium specimens of flowering plants, ferns and the larger algae are customarily dried between sheets of heavy blotting paper or construction felt under pressure so that the drying specimen is flat. Most specimens dry in about a week, if the blotters are changed several times. The drying can be speeded up by interspersing ventilators of corrugated cardboard among the blotters. The dried and pressed plants are then mounted in a herbarium in a manner that best illustrates the characteristics of the plants.

Nineteenth-century botanists, both amateur and professional, used herbariums for identifying and conducting research on plants.
