50 LIFE HISTORY OF NORTH AMERICAN TICKS. 
were deposited lasted only three days, it usually continues during the 
summer months for from 6 to 10 days. After the fourth deposition, 
engorgement of the ticks became more difficult with each succeeding 
deposition. This seemed to be due largely to the weakened condition 
of the ticks. It therefore appears that in nature ticks seldom engorge 
and deposit more than five times. It seems probable, however, : 
that if the first engorgement were made early in the spring and the 
ticks were engorged as soon as possible after deposition was com- 
plete, a greater number of annual depositions would occur and prob- j 
ably the total number of depositions would be increased.
