Total for 29 trout, 31 6f 38,580 



The avera,s:e \vei,c^ht of fisli taken tlirougiiout the season will 

 exceed that dednced from the alcove table, the males averaging' 

 in weight much more than the females. There is a very marked 

 difference in the size of egg's of brook trout taken from different 

 waters, and the size of the eggs does not depend upon the size 

 of the fish. The variations in size of eggs taken at three field 

 stations last season were in the proportions of 34, 41 and 42 to 

 the square inch respectively. The eggs numbering 34 and 42 to 

 the square inch were taken from fish averaging five to the pound, 

 while the eggs 41 to the s(|uare inch were taken from trout 

 averaging over a pound each. 



I will not discuss the subject now, Init I believe that after suc- 

 cessful field stations like those I operate have become perman- 

 ently established, it will 1)e advantageous to study the conditions 

 surrounding the spawning grounds of each and see if the eggs do 

 not re(|uire different conditions of water supply in artificial work 

 such as volume of water to each trough, etc., to produce the best 

 results. 



Utility — In the collection of brook trout, the writer has always 

 borne in mind that eggs can l^e purchased at very low prices, 

 after they have been brought to the eyed stage; in fact, it is diflfi- 

 cult to attempt to compete with the commercial fish culturist in
