70 WORK IN THE HATCHING-HOUSE. 



three tanks each. In emptying the tanks a man stands, with one 

 boot in the water, on the ledge of the pond opposite the centre, 

 and at once pours the tank directly over the deepest part of the 

 pond. 



The depth of water spreads the fry before they reach the 

 bottom. At first we used to place the fiy in the shallowest 

 water near the inlet of the pond, but they were so frightened 

 they used to lie huddled together in masses. Probably the strong 

 light affected them after the semi-darkness of the hatching-house, 

 and instead of spreading they spent their time in trying to get 

 under each other a most unsatisfactory amusement, which 

 generally ended in the suffocation of some of them. When poured 

 into the deep water they instantly disperse, and in a few minutes 

 have spread all over the pond in a lively and inquisitive spirit, 

 Mens sana in corpore sano.
