NEW WORK 



ON 



SEA MOSSES. 



VITE shai! issue in a few days an elegantly illustrated '"Manual of American Sea 

 Mosses," prepared by Rev. A. B. Hervey. It is just such a work as has long 

 been needed and much called for: a handy, convenient book for sea-side use. 

 Nothing of the kind has been published in this country; Harvey's great work, com- 

 pleted 23 years ago, in three ponderous quartos, being too expensive and too cum- 

 bersome for general and popular use. 



It is a complete Collector's Guide, giving practical information as to the best times, 

 places and methods of collecti-.g the necessary apparatus, and the details of float- 

 ing out, pressing, drying, preserving, and mounting these beautiful plants. Full 

 directions are also given of the best methods of studying and identifying these jjants. 

 Full "'keys" ar<_ given, at the head of each group, by which the most inexperienced 

 may be easily guided to the genus to which the plant he is studying belongs. 



While in the description of species the method of treatment is popular, and 

 especially adapted to the need of amateur botanists and sea-side collectors, all the state- 

 ments are made with scientific accuracy and carefulness. All the common species 

 belonging to the three great groups of Green. O'ive Col red and Red Algae, are taken 

 up in order, and so described in detail, that it is believed they may be easily identified 

 whenever found. The book is thus made a complete guide to all the common and 

 beautiful forms of our Atlantic flora, r.orth of the Carclinas. including nearly all the 

 characterist : c forms of the Pacific coast, for California, Oregon and the North. 



The plates, twenty in number, are drawn and colored from nature, and represent 

 twcntv-four of the most interesting, beautiful and characteristic species, in not less 

 than nineteen genera. 



The work is issued in eletram binding, 12 mo., over 300 pages, and is printed on fine, 

 heavy paper, with 20 ful'-paged colored plates. Price, postpaid, $2.00.
