 be disturbed hereafter. 



It is gratifying to know that after the lapse of 

 quite a number of years Familiar Trees is a suffi- 

 ciently successful book to require a second revised 

 edition. This revision in a great measure relates to 

 its scientific nomenclature which follows the initia- 

 tive of the seventh edition of Gray's Manual, revised 

 by Dr. B. L. Robinson and Prof. M. L. Fernald, 

 and under their supervision illustrated by me. It 

 has been my privilege, therefore, to acquire a clearer 

 insight into the reason and need for the nomencla-
