INTRODUCTORY EDITORIAL NOTE I LOOK upon this little volume as a distinct acquisition to the Peeps at Nature Series, and I am confident that it will receive a kindly reception on the part of those who desire a well-illustrated, reliable, and at the same time inexpensive, book on ferns and their allies. The author has packed a great deal of information in a small space he has dealt with a difficult subject in a simple way. As a practical field botanist and close observer, he is well acquainted with the difficulties of identification, and the following chapters are the result of experience. The book will be valued by the general Nature student as well as the young beginner. The author has dealt with all ferns and their allies regarded by Sir J. D. Hooker as definite British species, with two exceptions i A Fern, Gymnogramme leptophylla and 2 a Quillwort, Isoetes Hystrix. These two plants are British only in a political sense, being restricted to the Channel Islands. 862217 CHARLES A. HALL. CONTENTS CHAPTER PAGE INTRODUCTORY EDITORIAL NOTE V I. PAST HISTORY, I II.
