CULTURE OF THE SALMON. 133 



" In relation to the DoohuUa river, — I should rather say 

 the Doohulla waters, because there is nothing which can 

 well be dignified by the name of river connected with the 

 concern. There are several small loughs or lakes which 

 now discharge through two artificial cuts, one connecting 

 the upper lakes with the lower one, and the other connect- 

 ing all with the sea, and more in the character of mere 

 ditches than of rivers. The whole catchment area (as 

 engineers call it) of these small lakes is very inconsidera- 

 ble; they always contained some white trout which 

 ascended through a tortuous stream or brook, when heavy 

 rains created occasionally sufficient water in its rugged 

 bed ; these favorable opportunities however were few and 

 very far between. This place was purchased some years 

 ago by Mr. John Knight Boswell, of Monkstown, near 

 Dublin. He requested me to assist him in such measures 

 as might be adopted for the improvement of the fishery. 



" The main principle carried out, was that of connecting 

 the waters of the several loughs; cuts were made to efi'eot 

 this — the old stream was dammed out, the water was run 

 through an additional lake before unconnected with the 

 others. The speculation was a complete success, though 

 a valuable white trout fishery only was created when Mr. 

 Boswell sold it, realizing a large profit for his outlay." 



The following, which relates to the same waters after 

 coming into possession of Mr. Cooper, is from a letter of 

 Mr. Eamsbottom : — 



" It is four years this month since the first lot of ova were 

 deposited, viz., 18,000. These, when hatched, were kept
