EDITORIAL 



Before consenting to relieve our good friend. Dr. Grout, of the burdens of 

 editorship of The Bryologist, the present writer paused for long and serious 

 thought, knowing full well the none too sufficient time at his disposal for such 

 work. However, friends and co-workers everywhere have promised to help, and 

 some have already been of great assistance, and your Editor feels that the work, 

 as well as our mutual relations, will be none other than most pleasant. We hope 

 to be able to keep The Bryologist up to its present standard of excellence, and 

 friendly criticisms and advice will always be most welcome, particularly from 

 those to whom is due the excellent and steady development of our magazine.
