Biography/History:
The Purnell Act was passed by congress in 1925. It provided federal money to state Agricultural Experiment Stations for research on agriculture as well as the related economic and sociological factors. The University of New Hampshire took full advantage of the funds and has conducted hundreds of experiments on a whole range of topics.

Scope and Content:
This series contains the files on the various research projects performed using the funds provided by the Purnell Act. The files are arranged according to project number.
