The buffalo fry which died a few mihutes after the pond was poisoned had almost 
disappeared by the next morning, They were eaten by the larger fishes, which were 
affected somewhat later, A large water snake (Natrix sipedon) was caught. Although 
unaffected by thé poison, this snake was sluggish because it had swallowed about two 
pounds of fish, <A pectoral spine of one of the bullheads had punctured its stomach 
and body wall, and yet it survived, A few small fish were eaten by birds, principally 
by the little green heron, No turtles were seen, 
Dip nets were used from two boats to pick up fish, Other nets were used by men 
who walked along the shore or waded in the shallow water, The fish were sorted by 
species into tubs, buckets and baskets, Each kind was counted and -then weighed in 
convenient lots on a Chatillon spring balance, This balance weighs to 60 pounds by 
l-ounce intervals. It was suspended on a heavy tripod, The fish were weighed promptly 
after collection to avoid losses by drying, The standard length of almost every fish 
was taken on measuring boards to the nearest 0.1 inch. Lengths of all the numerous 
small black bullheads and golden shiners were not taken, but large représéntative 
samples were measured. The total numbers, total weights and average individual weights 
of the different kinds of fishes found in Fork Lake are shown in table 4, Length 
measurements of the more important species are grouped in #+-inch classes in table 5.
