436 THE KEEPERS BOOK 



Complete success has crowned the efforts of the 

 experimenter, as salmon ova not only hatched out in 

 the effluent three days earlier than in the Spey water, 

 but the fry grew faster in it than in the ordinary 

 water. 



Another discovery worthy of notice is a cheap 

 way to supply feeding to lochs before stocking with 

 trout. To encourage food, place large bundles of 

 bracken, weighted down by large stones, all round 

 margin of loch in two feet of water, and allow 

 it to decompose ; this will prove a hatchery and 

 sanctuary for mollusca and all sorts of fresh-water 

 shrimps ; a large increase in size of trout will soon be 

 observable. P. J. M.
