 Departments. Exebange Column, (free to all subscrib 

 ers), etc.. etc. 



To those who know the Bulletin, it recommend.^ 

 itself. To those who do not Iniow it. we would .say 

 that The Asa GR.4Y Bulletin tills a place occupied 

 by no other Uotanical magazine. Among its contrib- 

 utors are the eminent educators and students of our 

 country. Nothing is published unless it Is true, we 

 do not deal in the public fancies of the day, nor in the 

 product of fertile imaginations. The Hulletin is the 

 medium by which the lover of ttowers and tlie student 

 of Botany can give to science their ciwn (iplnlnns and 

 investigations. It does not preti'nd li> d.-al with any- 

 thing or a highly technical nature, but does what no 

 other Botanical magazine does. It follows the study uf 

 plants as he, whose name we try to honor, did, and to 

 all who love the Botany that Dr. Gray loyed. the Bul- 

 letin iec(»mmeds itself. 



Kvery High School and College Library should have 

 the Bui.i.ETiN on Hie as it will give the impulse to stu- 

 dents 10 look into this liiiijortani science. 



Every Teacher and .student should take the Bulle- 

 tin a.s it shows what other Teachers and Students 

 are doing, and will thus help each in his own work.
