324 FIFTEENTH ANNUAL REPORT OF THE 



eggs shipped to us or from eggs taken in a lake or stream that at some former 

 time had been stocked with diseased fish. I have recently learned that the 

 disease has been found in the perch in some of the lakes in Maine. 



Another point which should receive close attention is the food we are 

 feeding, which in my opinion causes more trouble in our hatcheries than 

 anything we have to contend with. This is a matter of great importance 

 and in my judgment will have much to do with fish culture in the future. 



For the benefit of those who have not seen the tumor disease I will 

 mention a few points to observe. Look into the fishes' mouths and if there 

 you find small red boils your fish are doomed. They may live two or three 

 months but before that time the disease will break out on the outside in 

 some and in others will grow entirely on the inside. In either case the 

 results will be the same. 



At the station some improvements will be carried out during the 

 coming year. Among these will be using water from artesian wells separate 

 from our other supply, so that we can compare results. A full report will 

 be made as the work goes on. Yours very truly,
