How to Know Wild Fruits. By Maude Gridley Peterson. (Macmillan
and Co. 6s. 6d. net.)—The peculiar object of this book is to guide the searcher when the tree or plant is not in flower, and when the means of identification are limited to fruit or leaf or both. After an interesting chapter on the "Protection and Dispersal of Seeds," we have a guide to the families dealt with, a list divided according to colours of the species described. It should be said that the book refers to the United States and Canada. It will not be without use here ; but we cannot boast anything like such a catalogue. This contains between two or three hundred. Of well-known British plants, we see the bar- berry, bilberry, blackberry, cranberry, currant (six varieties), gooseberry (five), mulberry, and raspberry (six).
