Analytic Keys to North American Mosses. 



The naming of mosses by the use of the Manual of Lesquereux and James alone 

 has been found to be most difficult by amateurs who have no other aid. These 

 keys, on the general plan of those in Gray's Manual, will enable students and 

 collectors of mosses with comparatively little experience to name correctly most 

 of the species they can collect. 



Seventy-two Pages, with strong Manilla Cover. 



A supplement, ready shortly, will be sent with each copy, gratis. 



Single copies, 50 cents; 12 copies for $5.00.
