PREFACE
proportion of our native ferns during a single summer, and it is still more surprising that so few efforts have been made to bring them within easy reach of the public.
I wish to acknowledge my indebtedness to the many books on our native ferns which I have consulted, but more especially to Gray's "Manual," to Eaton's "Ferns of North America," to the "Illustrated Flora" of Messrs. Britton and Brown, to Mr. Underwood's "Our Native Ferns," to Mr. Williamson's "Ferns of Kentucky," to Mr. Dodge's "Ferns and Fern Allies of New England," and to that excellent little quarterly, which I recommend heartily to all fern-lovers, the "Fern Bulletin," edited by Mr. Willard Clute, of Binghamton, N. Y.
To the State Botanist, Dr. Charles H. Peck, who has kindly read the proof-sheets of this book, I am indebted for many suggestions; also to Mr. Arthur G. Clement, of the University of the State of New York.
To Miss Marion Satterlee thanks are due not only for many suggestions, but also for the descriptions of the Woodwardias.
The pen-and-ink illustrations are all from original drawings by Miss Satterlee and Miss Alice Jose-
