Eaton's "Ferns of North America" has been out of print for some time and
is constantly advancing in price. We can offer a second-hand copy, the
two volumes bound in cloth, clean and in good condition, for $35.00,
express paid. There are 81 colored plates, and all the North American
ferns are described. Address,
THE FERN BULLETIN, Binghamton, N. Y.
