5.— SUMMARIES. 



The following statement shows the number of salmon bought for 

 breeding stock, and the number brought to hand in the spawning-season, 

 for three years past : 



The following exhibits the number of salmon-eggs taken, lost, and 

 distributed at Bucksport, and the number of young set free as the 

 result of their hatching, for three years : 



* The first estimate -was obtained by measurement of the egga at the time they -were taken and 

 placed in the hatching-troughs. The second estimate is obtained by adding the number known to have 

 been thrown ont to the number distributed among the subscribers. The discrepancy between the two 

 estimates is, in 1873, nearly G per cent, of the original estimate ; in 1&74, less than 2 per cent.
