238 FLY FISHING 



an interesting experience in the first autumn 

 flood in the following October. I had con- 

 structed a sort of wire trap below the pond, 

 in the hope of catching in it any fish which left 

 the pond during floods. It was a very imperfect 

 affair, for it was quickly blocked by leaves and 

 overflowed, but after the first flood in October 

 we took thirty-nine Salmo fontinalis out of it 

 and replaced them in the pond. As there were 

 at most only seventy-five fontinalis in the pond, 

 it was certain that more than half of them had 

 made a determined effort to get down stream, and 

 it is probable that several others, besides those 

 recaptured, had escaped from the trap and gone 

 away altogether. The number of trout in the 

 pond was about double that of the fontinalis, 

 and yet not a single trout was found in the 

 trap a striking illustration of the difference 

 in the habits of the two species of fish and of 

 the much greater difficulty of retaining a stock 

 of fontinalis. 



In May 1891 the fontinalis in the pond had 

 reached a weight of fourteen ounces; whilst 

 in August one of one pound one ounce was 

 caught, and the last ever seen there was in
