Salmon grow to a great size, sometimes reaching to- 

 upwards of 70 pounds in weight > but such are very un- 

 common : their average, in great rivers, may be from 1 1> 

 to 30 pounds j. in the iesserstreams, from. 8 to 2O pounds 

 constitute the general run. 



They are not considered as salmon until after the fifth. 

 year, till which time they are known in different countries 

 by various names, some of which, are applicable to their 

 annual growth. Thus, during the first seasort they are 

 called " salm on-fry" or " smelts ;" in the second year r 

 " sprods" or spurts ;" then <{ morts-" "fork- tails-," 

 " half-Jish -" according as they appear to be advancing 

 towards tlieir final designation. 1 consider it; however, 

 a difficult matter to fix the age of a salmon, thus exactly,. 

 and rather approve of the Scotch mode of classing them. - 



In that quarter, all marketable fishes,, that is, such as 

 cannot pass the cruives, or salmon-traps, are called 

 *' salmon ;:" while, such as can make their way past them, 

 are known by the general uame of " grills" 



Cruives are made in the rivers throughout Scotland,, 

 of those large pebbles every where abundant. They con- 

 sist of a short, but immensely substantial, barrier, raised 

 in the middle of the stream, by placing tlue stones loosely 

 to the thickness of many yards,,, with a considerable, 

 slope, especially within. At the ends of this barrier, are 

 two railed cages covered over with plank, and firmly fas- 

 tened by piles and by arms, to both the. bottom, and the 

 rampart. 



From the exterior of the cages, or traps, two. very sub- 

 stantial buttresses ot* loose stones diverge, so as to gs
