126 AMERICAN FISH CULTURE.

 Lough Mask with half a million of salmon ova. These 

 operations have been so lately completed, that we hardly 

 know as yet what measure of success will attend them ; but 

 I see no reason for doubting their success, and, if so, a 

 capable area of about thirty square miles will be added to 

 Mr. Ashworth's already valuable fishery, and in a few 

 years' time the fishery will realize a handsome fortune. 

 This shows what can be done by pisciculture, in its broad 

 sense, and a little practical common sense combined." 



To the foregoing I would add, that from information 

 obtained from another source, Mr. Ashworth laid down 

 in the season of 1861-2, no less then a million and a half 

 of ova. 



I would also state that Mr. Frank Buckland, a naturalist 

 who takes much interest in fish culture in England, has, 

 since the publication of Mr. Francis's book, examined the 

 ground between lakes Corrib and Mask. His report is 

 adverse to the efficiency of the fishway there used. He 

 says that the natural outlet from the upper to the lower 

 lake, is underground, through broken and cavernous rocks, 

 and that the channel for the fishway is in the bed of an 

 abandoned canal, three and a half miles long, through 

 rocky ground full of fissures and sink-holes. That the 

 passage, even with the improvement made by laying down 

 a thousand feet of iron pipe, three feet in diameter, is 

 impracticable to salmon in the spring of the year, from the 

 force of the current ; and in summer, from the scarcity of 

 writer. And further, that the young fish leaving Lough
