This book is thoroughly authoritative, and is written in popular style. It covers all the ferns in the region embraced either in Britton's or in Gray's Manuals.

"This book is likely to prove the leading popular work on ferns. No finer examples of fern photography have ever been produced. Dr. Waters brings to his work fifteen years of experience in field and herbarium study, and the book may be expected to prove of permanent scientific value, as well as to satisfy a want which existing treatises have but imperfectly filled."—Plant World.

"For all who study or wish to study our native ferns Dr. Waters has prepared a book which is sure to prove both helpful and inspiring. Especially charming and significant are the views showing typical habits and habitats."—The American Naturalist.

"There could hardly be a better book for those interested in the subject."—Boston Literary World.
