Nearly every fern student seems to have a copy of “Our Ferns in Their Haunts,” but if you happen to know of one who doesn’t, you could scarcely do a more graceful thing than to give him one for Christmas. You may be sure the book will be consulted many times next year and in the years to follow and every time this happens the giver will be thought of with pleasure. If you have a young friend who is beginning to get interested in Nature, crystalize his tendency by giving him this book. The illustrations will make him a lover of ferns and the text will make him wise about them. There are 225 illustrations and 340 pages of text. No other fern book is so full, so clear or more accurate. The key for identifying the ferns has illustrations of fruit-dots and even a child can name the ferns by its use.
