Mosses and lichens has been written with the hope that it may meet a need often expressed, for a book with pictures which will help to identify some of the many beautiful growths which, winter and summer, in wood and Open, excite the admiration and arouse the curiosity of all nature lovers. It is the result of the author's desire to know something of the dainty plants which are so lavishly employed by nature in beautifying the trails and brooks of the North woods. The more striking mosses and lichens were collected and carried about until by the kindness of one friend and another learned in mosses, names were secured for them.
