Taken from Discussion and Summary:

This investigation explores the potentialities of the bark, wood, leaves, and capsules of the Eucalyptus, Tasmanian Blue (Globulus), Longbeak (Teritocornis), Red-Ironbark (Sideroxylon), and Longbeak (Rostrata), as a domestic source of tannin. The trees were identified by Dr. Ernest E. Stanford, Professor of Botany, College of the Pacific.

Results are based on hot plate dried weights and are recorded in the following Tables and Figures. Trees were chosen from the local area, Stockton, California, and from Tracy, California, to determine significant variations between localities.

Analysis of the extracts followed the official methods of the American Chemists Association (1946) with no exceptions.
