Mr. Harvie-Bro-wn informs me of a cliaiii of lochs in Scotland containing 

 charr. In one small, deep pool of crystal-clear water they are of a larger size 

 than those inhabiting the lochs lower in the valley. In a perfectly dead calm 

 they rise, sometimes freely, to a certain fly, but cease whenever a ripple disturbs 

 the surface. As many as six dozen have been taken by one rod in a single day. 

 One can see several feet down into this basin of pure water in a calm, and perceive 

 the fish floating upwards and sucking in the fly, as they seldom dash at it like a 

 trout. 



Charr, says Mr. Jackson, except for a few weeks in the year when it appears 

 to live on flies, preys on all small fish and captures them, even larger than would 

 be supposed possible by any one who has not taken (as I have) a perch nearly 

 two inches long out of a charr about nine inches in length.
