little fish are soon found in great numbers in them. More especially 
is this the case if the loch is understocked with trout. One loch 
which I made was simply alive with sticklebacks for about 20 feet

of sticklebacks was very soon reduced. ‘Their favourite haunts are 
the backwaters of streams, the sides of lochs among weeds, small 
ponds, and ditches.
