MEXICAN BEAN BEETLE IN THE SOUTHEAST. — 35 
In dust experiments, treatments in some instances followed closely 
on account of frequent heavy rains. 
In experiment 1(c) the pulverized stone lime was not ground suffi- 
ciently to obtain a good application, and the amount applied was 
therefore excessive, as much dust fell to the ground. 
The per cent of reduction in yields due to treatment, with the check 
plat as the basis, does not take into consideration bean beetle injury 
to the check, for in ali experiments where this calculation is made 
Epilachna injury did not reduce yields to a very great extent. The 
insecticide injury as affecting yields therefore is shown rather lower 
in this column than is actually the case, for there is no way of accu- 
rately determining the reduction in yield in the absence of insect-free 
checks. 
Check plats, except in a very few instances, were of the same size 
as the treated plats. In some cases two check plats were used, each 
_ the same size as the treated plats.
