TO MEMBERS OF AMERICAN NATURE-STUDY 



SOCIETY AND SUBSCRIBERS TO THE': 



NATURE-STUDY REVIEW 



' As announced in the May issue, The Xature-Study Review must be pub- 

 lished after this year on the full financial responsibility of the American 

 Nature-Study Society. For this reason there must be made before the 

 annual meeting in December an absolutely safe estimate of income for iqio; 

 and to tins end the present officers request that members and subscri- 

 bers cooperate either by paying igio dues before Dec, to, or by notify- 

 ing the secretary that they will renew early in igio. Experience shows 

 that there is no basis for a safe estimate as to probable number of re- 

 newals. 



Cooperation in the work of increasing membership is needed. One 

 member has sent thirty ^new names this month. The Society needs at 

 least 1500 members for 1910. 



Also, more subscriptions toward a possible deficit of $300 to $500 next 

 year is needed. One-half of this amount is already guaranteed by mem- 

 bers who pledge amounts varying from $2.00 to $100.00. In case of a 

 deficit which will probably occur unless the membership is raised to 

 1200, it is proposed to make a proportionate division of responsibility 

 among the subscribers to the deficit fund. A large number of such 

 special subscriptions will reduce the individual liability and at the same 

 time protect against great personal loss the officers who undertake to 

 conduct the work of the Society. For further information see The 

 Review for May, 1909.
