Complete eacterminat ion of individuals mm observed over most of the ares 
personally examined* There were* however* several spots seen in which the 
Bird and Insect populations were-only partly destrojjed • am spots of 
survival* at least in the upper levels of this relatively ■' lose jungle* 
were probably due to the uneven concentration of the agent used* produced 
by the assy small units introduced* necessarily not completely imiforn

the Area I) (enlarged) wherever the concentration of the agent used was 
great* The spotty survival of some animals was due to the irregular 
concentration of the agent attained by the means used for its introduction 
into JD ares on Sept* 11th
