THE JOURNAL IN THE CLASSROOM 



A Special Rate to Teachers 



The principal object in establishing the American Genetic Association 

 was to encourage a wide interest in the problems of practical breeding, 

 genetics; and eugenics. Therefore it is gratifying that the Journal of 

 Heredity is being increasingly used as a supplement to textbooks in the 

 teaching of biological subjects. To call attention to the method, and to 

 determine whether the Journal has a wider application in this field, it is 

 being offered at a special rate to members actively engaged in teaching in 

 colleges and secondary schools. Ten or more subscriptions covering the 

 eight-month school year will be accepted at the rate of $1.50 each — half the 

 annual membership fee. Four month subscriptions on the same basis will 

 be 75 cents. It is hoped that sufficient members will avail themselves of 

 this offer to justify its becoming a permanent policy in the future.
