History and Habits 33 



done the fish gather in shoals and drop down 

 stream till the sea is reached. 



In the Fishing Gazette for September 2, 1893, 

 is a table by Mr. E. Sturdy for estimating the 

 weights of salmon by their inches of length, of 

 course assuming the fish to be in average con- 

 dition. As these trials were made on one river 

 and for a part of one season only, by Mr. Sturdy, 

 it might not be safe to base any general law on 

 them. The table is as follows, and I have, in giv- 

 ing it, not gone into the fractions of pounds in 

 the original, but simply put down the approxima- 

 tions to quarters of pounds : 



"A fish of 30 in. weighs 12^ Ibs. A fish of 41 in. weighs 29 \ Ibs. 



A fish of 31 in. weighs I2| Ibs. A fish of 42 in. weighs 3if Ibs. 



A fish of 32 in. weighs 14 Ibs. A fish of 43 in. weighs 34 Ibs. 



A fish of 33 in. weighs 15 \ Ibs. A fish of 44 in. weighs 36^ Ibs. 



A fish of 34 in. weighs i6f Ibs. A fish of 45 in. weighs 39 Ibs. 



A fish of 35 in. weighs 18^ Ibs. A fish of 46 in. weighs 4i| Ibs. 



A fish of 36 in. weighs 20 Ibs. A fish of 47 in. weighs 44 Ibs. 



A fish of 37 in. weighs 2if Ibs. A fish of 48 in. weighs 47$ Ibs. 



A fish of 38 in. weighs 23$ Ibs. A fish of 49 in. weighs 50$ Ibs. 



A fish of 39 in. weighs 25^ Ibs. A fish of 50 in. weighs 53$ Ibs." 

 A fish of 40 in. weighs 27$ jbs. 



It is my impression that there may be very 

 sensible variations from this table, particularly in 

 large fish, depending on the difference in con- 

 dition. I once measured accurately a female
