Plant material

Analytical Herbarium : Designed for the Use of Students and Private Collectors was published in Farmington, Maine, in 1886 and used to collect botanical samples between May and June 1887.

This collection consists of two albums of specimens of dried and pressed plants and wild flowers made by early nineteenth-century London Grove, Pennsylvania, botanist John Jackson between 1810 and 1819. One of the albums was given to Dr. Francis Alison (1751-1813), son of the Presbyterian minister and educator Rev. Dr. Francis Alison (1705-1779).

The Miriam E. Welliver travel journal documents this Pennsylvania school teacher's month-long, 5,100 mile automobile trip across 19 states and Canada via handwritten journal entries, black-and-white photographs, postcards, telegrams, plant specimens, pamphlets, and other miscellaneous materials.
