THE AMERICAN BOTANIST 155 



sent to a few editors in exchange for their own publications 

 because, being people of intelligence, each wants to see 

 what the other is doing. It would, of course, be possible 

 for each editor to send cash for the other's publication, but

In common with other magazines, we annually re- 

 ceive a considerable number of subscriptions for a single 

 year. Some of these subscribers renew and some do not. 

 To compensate us for the trouble of recording new names 

 and correcting our mailing list, the annual subscriber 

 naturally pays a higher rate. When the subscriber saves 

 our time and his by paying for two years in advance, we 

 make a reduction of 50 cents. If he' chooses to become a 

 "permanent" subscriber, asking that the magazine be sent 

 until it is ordered discontinued, he pays at the rate of $1.00 

 a year thereafter. To get on the Patron's list one must now 

 own a full set of the magazine. There are only 35 chances 

 to get on this latter list because we have only 35 more full 

 sets'. Anybody who has been thinking of ordering a full 

 set should consider the idea of making himself a Christmas 

 present of one.
