"State Floras."—There are some excellent State Floras, and in order to keep this list from being too long, it is suggested that the Scout leader write to the Professor of Botany in her State University and ask for the name, author and publisher of the best Flora of her State. Especially is this advisable for those living in sections of the country not covered by the above references.

"Field Book of American Wild Flowers," F. S. Matthews, Putnam.
