New England Ferns and their Allies.'— This attractive little 
volume is intended as a popular guide to the New England ferns, 
club-mosses, and horse-tails. In a preliminary chapter, the various 
species are grouped first by their fruiting seasons, and then by the 
nature of their habitats. Each species is then described briefly and 
the more evident characteristics of closely allied forms are contrasted. 
Brief remarks follow on the general distribution, habit, and manner 
of fruiting. The descriptions are supplemented by one or more 
excellent illustrations of each species from photographs of fresh 
specimens. A key to the genera of the ferns treated, a glossary, and 
an index conclude this handbook. It is substantially bound and of 
a convenient size, and cannot fail to be of service to the increasing 
class of out-of-door folk who wish to know the names of the plants 
met with in their summer excursions.
