^^fc-lASE RENEW WITHOUT NOTICE 



It v\ill be a great help in balancing EVOLUTION'S 

 budget if subscribers renew their subscriptions with- 

 out special notices and solicitations. Letters under first 

 class postage are always costly. Readers wanting the 

 EVOLLTION journal to succeed will co-operate in this. 



UNPAID SUBSCRIPTIONS 



Nearl\ a thousand nev\ sub^cribers secured by Mr 

 Katterfeld on his recent tour did not pay at the time he 

 met them, but agreed to remit for their subscriptions after 

 the receipt of the first cop>'. If you are one of these, 

 please consider this a sufficient reminder and send your 

 remittance for the subscription right away, in that wav 

 saving this office the expense of mailing out bills. 



EVOLUTION CIRCULATION 



EVOLUTION resumes publication with 7702 names 

 on its subscription list as follows; 



Subscriptions from individuals 7,338 



Subs, from libraries and institutions 311 



Exchanges 53 



Prepaid bundle subscription-. 255 



Dealers' bundle orders 1,514 



For High School sale> _... 2,529 



Total printed J~2T000~ 



Over half of this list consist^ of new subscribers, added 

 since our last issue appeared. The others are former sub- 

 scribers, being carried forward for the unexpired term 

 of their subscriptions. We expect to lose at least a 

 thousand immediatel\ . because many have died during 

 these years, and hundreds will have moved without leav- 

 ing forwarding addresses. Will you help to offset this loss 

 by sending in some new subscribers? To make EVOLU- 

 TION self-sustaining it must have ten thousand subscribers 



TEN ISSUES A YEAR 



So man\- of EVOLUTION'S subscribers are teachers 

 and students who tra\el during the summer that we've de- 

 cided to publish only during the ten school months, skip- 

 ping Jul)' and August. All old subscriptions at the |2 rate 

 will be extended the two extra months. 



We're mailing this issue in envelopes under postage so 

 EVOLUTION'S resumption will not be overlooked. The 

 next issue (Sept.) will go under second class entry. 



One of the Best Ways 



to get people that really need EVOLUTION to read it is to place it in all public libraries. Very 

 few libraries, working on budgets, will pay for a new journal now. But at least five thousand 

 libraries will agree to place EVOLUTION in their reading rooms if we send it free for a year. 

 We haven't the cash to do this, so appeal to our readers for a 

 Fife Thousand Dollar Library Fund 



with the understanding that for every dollar you contribute, some public library will receive 

 EVOLUTION for one year. A hundred dollar check will cover one hundred libraries. Let's 

 hear from you to the extent of your ability. Surely this is y 



An Eflucational Effort 



worthy of your best support. And this will help sustain the EVOLUTION magazine imtil 

 the individual subscription list grows large enough to carry it.
