The FERNS of NORTH AMERICA: 
ILLUSTRATED BY SUPERBLY-COLORED PLATES. 
Text by Professor Daniel C. Eaton, of 
Yale College. 
ILLUSTRATIONS BY MR. JAS. H. EMERTON. 
ROF. EATON’S herbarium of Ferns is the largest in America, 
and he is constantly in receipt of additional plants from all parts 
of the country. He is therefore in a position to better conduct the 
work and furnish the necessary specimens for illustrations than any 
other person. Besides the labors of Prof. Eaton and Mr. Emerton, 
Dr. Gray, of Cambridge, has expressed an interest in the undertaking, 
and kindly offered the use of the extensive herbarium of the Botan- 
ical Gardens for consultation. The Massachusetts Horticultural Soci- 
ety has also freely offered the use of the Davenport herbarium of Ferns. 
The publishers will also have the assistance of Mr. J. Robinson, well 
known as a Fern specialist. Mr. George E. Davenport and Mr. Chas. 
E. Faxon, of Boston, Mrs. Cooper, of Santa Barbara, Cal., and others 
in various parts of the country, have kindly offered their assistance. 
The subscription price will be $1.00 per part, which, it is believed, 
is lower than any work of the same nature and quality yet published. 
Botanists, who desire to inspect the work before subscribing, will 
receive a sample plate and text by mail, upon application. 
For the benefit of any young botanists who do not feel able to pur- 
chase the work, the publisher offers an opportunity to obtain a copy by 
procuring a few subscribers in their vicinity. Any lady can easily 
obtain four subscribers for the work among her friends, and thus se- 
cure a copy for nothing.
