The Plant World is devoted to the interests of the general reader and of students 
and teachers. It therefore seeks to present each month in non-technical form the results 
of the development of botanical knowledge in the widest sense. 
Articles embodying the results of travel and research, general observation and ex¬ 
periences in teaching are desired for publication. Authors are however especially urged 
to render such articles in non-technical form. 
Subscription, $i.ooayear (12 issues); Single copies, 15 cents; Foreign postage, 
25 cents additional. If local checks are used ten cents must be added for collection. 
This charge is necessitated by the rules of the New York Clearing House. Make paper

IMPORTANT NOTICE TO SUBSCRIBERS 
The exigencies arising from the reduction of the price of THE PLANT WORLD, 
and from the change of editorial office together with the necessary financial arrangements, 
make it difficult for us to make the proper adjustments with our Subscribers. We 
shall therefore follow this procedure: Those who have already paid up their 
subscriptions in advance will be credited forward , after the accounts are closed for 1904, 
on the basis of our present rate of subscription , unless we are requested to do otherwise.
