were fed 65 per cent, and Lot Xo. 4 only al)Out 50 per cent of 

 their capacity. Lot Xo. -i was in a larger ])ond where they se- 

 cured some natural food in addition to their daily rations. From 

 this time until the Following August they were fed twice per day, 

 then but once till the commencement of the spawning season 

 (Xovember) when they were fed l)ut three times per week. Xo 

 markd difference was noted as to health amongst the various lots, 

 although the death vAie, which was only nominal, was a trifle 

 higher amongst the smaller fish. In the matter of growth how- 

 ever the difference was most markedly in favor of those receiv- 

 ing the larger rations. A monthly record of the growth of Lot 

 Xo. 1 was kept for one year, as follows :

This included l)oth males and females, the former being 

 naturally somewhat larger. One day during the spawning sea- 

 son ten representative females were selected from each lot and 

 weighed, prior to stripping, to ascertain the comparative growth :
