 pond experience has been a mode of preparation. The 

 planning of the boxes, ponds, sluices, etc., has been accom-

 the whole apparatus is not three times the size, so that the 

 Tay proprietors might breed annually a million of salmon, 

 which would add largely to the productiveness of that river, 

 and of course aid in increasing the rental. 



For the purpose of showing the level of the pond at Stor- 

 montfield I beg to introduce what the French people call " a

A. Source of water-supply. 



B. Pond from which to filter water 



on boxes.

E. River Tay. 



The salmon-breeding operations at Stormontfield originated 

 at a meeting of the proprietors of the river Tay held in July 

 1852, when a communication by Dr. Eisdale was read on the 

 subject of artificial propagation ; and Mr. Thomas Ash worth of 

 Poynton detailed the experiments which had been conducted 

 at his Irish fisheries. This gentleman, who takes a great and 

 practical interest in all matters relating to fisheries and the 

 breeding of fish and to whom I am greatly indebted for 

 practical information said that he had long entertained the 

 opinion that it would be quite as easy to propagate salmon
