 where they were collected. Account was kept 

 of the number taken between six-thirty a.m. and 

 five P.M. During a period of twenty-two days it

 total number entered the nets between six-thirty 

 and eight A.M. The total catch by this method 

 under five houses in the same period was 14,322 

 adult Anopheles, mostly Anopheles tarsimaculata. 

 These came from ground-cracks under the house
