THE LOCH PROBLEM 
185 
about 5 feet. Its bottom is for the most part 
fairly hard ground, but on one side there is soft 
mud, and on another side, for about an acre and 
a half, the bottom is rocky. I began stocking 
the loch in 1910, and during the first three years 
put into it small trout from burns and other 
lochs on my ground, but in 1913 and 1914 put 
into it 150 and 200 Loch Leven yearlings respect- 
ively. These yearlings were supplied from one 
of the well-known hatcheries. In 1915 I put no 
trout into the loch, but since, and including 1916, 
I have put in every year on an average about 
eighty small trout taken entirely from burns — 
one of which runs into the sea and contains the 
young of sea-trout as well as small brown trout. 
The following table shows the exact numbers of 
fish put into the loch, showing a total of 1062.
