OBSERVATIONS ON INSECT LIFE 175 



along- the margin of the pool, insects start up from 

 the dried grass. Locusts tumble into the pool and 

 are swallowed by greedy frogs lying in wait upon the 

 surface. Smaller insects, in their efforts to escape, 

 fall a prey to a shoal of water-bugs and are suffocated 

 in the stream. Others, that escape the water, meet

 below in ambush amongst the green weeds are the 

 patient crabs to whom the frogs themselves are prey. 

 It is a merciless and cruel battle between all the 

 inhabitants of the pool ; there is no rest from the 

 continual warfare, no prospect of peace. To each

 with fish, so tame and so dependent on their owners

 creatures. These fish are objects of veneration 

 amongst the Hindu Pandits. They may not be 

 captured, but I feel sure they are the common species 

 of mahseer, Barbus tor. The fish grow to a large size 

 and people the tank in such numbers that, were they
