after trout were first put into it. Every fish 
caught under a pound, with very few exceptions, 
has been returned to tlie loch, but it is a curious 
fact that the fish rise very little until they reach 
about a pound in weight, and so we have not been 
troubled much by catching the smaller fish which 
would have to be returned to the loch.

showing a total of 216, weighing 482 lb. 1 oz.,
