In 1908, when this magazine changed from a monthly to 

 a quarterly, we adjusted the differences in the subscription 

 price by giving a subscription for a year and a half to all who 

 had paid for one year in advance. This extension made a 

 large number of subscriptions end with the May number in 

 the middle of a volume instead of at the end, as formerly. 

 Since there are a large number of subscribers who like to have 

 their subscriptions end with the year and the volume, we take 

 this occasion to point out that all subscriptions ending with 

 the present number will be extended to the end of 1910 upon 

 payment of a dollar. This extension is offered, however, 

 only to those who pay in advance and we trust all will take 

 advantage of it. Bills for all subscriptions due will be found 

 facing the frontispiece in each copy. These are made out for 

 one year in advance but the extension of the time suggested 

 may be obtained by the proper payment.

For the first time in seven years the editor of this maga- 

 zine will not visit the Eastern Chautauquas this year. Instead 

 he will have charge of summer classes in botany for teachers 

 at the University of Illinois. Other classes in systematic bot- 

 any and ecology will be in charge of Dr. H. A. Gleason, well 

 and favorably known to readers of this magazine. Work in 

 the summer session begins June 21st, and runs for nine weeks. 

 Teachers who contemplate brushing up their knowledge of 

 botany will find Dr. Gleason's classes a most efficient means 

 to that end and we venture to assert that the other work in 

 botany will be no further behind the pace set than conditions 

 make necessary. ^ ^ ^ 



During the summer of 1909 Dr. E. F. Bigelow will con- 

 duct a summer school for nature study at Sound Beach, Conn.
