224 SALMON, THREE, FOUR, FIVE MONTHS OLD. 



The 3rd figure on the plate represents the 

 two months old salmon-fry. In length it is l^ 

 inches. Its shape is perfect, and its fins are well 

 defined. The transverse bars, beginning at the 

 lateral line, are visible ; but not so brilliant and 

 large as they afterwards by degrees become. 



The 4th figure is that of a salmon-fry four 

 months' old, or a day or two more or less, and 2| 

 inches in length. The transverse bars, com- 

 mencing above the lateral line, have increased in 

 size and depth of colour ; and little spots are visi- 

 ble on the back. The fins are very large in pro- 

 portion to the size of the fry, showing that it is 

 the young of salmon, and not of any small species 

 o^ salmonidm. The fins of a trout of the same size 

 would be much smaller. 



The oth figure is that of a young salmon, at 

 the ao;e of six months. The drawinoj is that of a 

 specimen more perfect in shape and colour than 

 ordinarily. It is 3^ inches in length ; its colours 

 are deepening, and the transverse bars are more 

 largel}' developed. Its fins are disproportionably 

 large in respect to the size of the body. Hitherto 

 its growth has been rapid ; but at its present age 

 it, generally speaking, enters the cold months, and 

 during four of them, its growth, chiefly from want 

 of insects for food, is very slow.
