174 CHARLES C. GROVE 



Dear Doctor: 



Since a certain piece of desirable research cannot be done without your co-operation 

 together with that of a limited number of thoughtful, scholarly workers in the field, may 

 we not ask your prompt consideration of the schedule given below, basing your judgments 

 on your ( ) years of professional practice, involving ( ) cases. 



We do not ask your name, only — 



(1) Fill in the two blanks above. 



(2) Check the spaces on the left, indicating a cause. 



(3) Give the approximate percentage of cases on the right. 



(4) Add any further information and remarks on the reverse side. 



(5) Return by early mail in enclosed stamped envelope. 

 Why are there fewer births per family than a generation or two ago? Because 



There are not fewer in percentum of cases 



Of economic conditions 



Of more concern for advantages to be given the child 



Of better understanding by women of what is involved 



Of physical inability on either side; then ( )%, now 



Marriage later in life (fewer, less favorable years of exposure) 



Interference with personal aspirations or pleasures 



Fear of hereditary disease 



Fear of childbirth 



Lowered ideals of sex relations 



. How the number of children is limited 



By continence 



By fewer and less favorable years of married life 



By better understanding by women of their right to choose 



By fuller knowledge of contraceptive measures 



Very respectfuly yours, 



Finally, minute details to cut down expense have been planned. For 

 example, stamped window envelopes with return address will be sent, into 

 which the post card for the pastor's reply will be so placed as to show his 

 name and address. On the same side he will place his request for some num- 

 ber of the forms. The return address on the reverse side will bring the card 

 back. The same card, showing the pastor's name and address will be pasted 

 on the package containing the number of forms requested right there on the 

 face of the card. These addresses will be printed on the cards by the addresso- 

 graph departments of the various denominational headquarters at very 

 reasonable rates. These cards can be bought in sheets and printed together, 

 saving press work, and then cut and sent to the addressograph departments. 

 The doctors will use the inquiry sheet for their replies and return them in 

 the accompanying self-addressed stamped envelope. These and other de- 

 tails will insure the economical and expeditious handling of the inquiry.
