NATURAL HISTORY OF BRITISH SALMONID^E. 125 



the fall between the two lakes being twenty-eight feet and the 

 length of the pass no less than one thousand feet. The pass 

 was nothing less than a huge iron trough, like half one of the 

 large water-pipes seen in the London streets, and about three 

 feet in diameter. The trough, which was made in England and 

 transported to Galway in separate pieces, was then fixed in its 

 place with coping stones and cement, at an expense which may 

 be easily imagined. It is some years since I have visited Cong, 

 and whether this splendid attempt has been successful in ' sal- 

 monising' the 23,000 previously barren acres of Lough Mask 

 I am, therefore, unable to say. I remember the opinion of the 

 late Mr. Ffennell and of Mr. Frank Buckland was far from 

 encouraging on the point. 



The great expense of ladders in different situations has 

 often stood in the way of their adoption, mostly to the detri- 

 ment, it need hardly be stated, of the fishing in the upper 

 reaches of the river. It may, therefore, be interesting to the 

 owners of fisheries, who are not already acquainted with the 

 very cheap and efficient floating salmon ladder lately con- 

 structed by Mr. Anton Pietsch, at Kurczyn, in Hungary, to 

 present them with a description of it, accompanied by such an 

 explanatory diagram as would probably enable any tolerably 

 intelligent engineer to erect a similar one in practice. For 

 this description, which is translated from the German of 

 Dr. M. Nowicki, of Krakow, by Mr. R. B. Marston, editor of 

 the ' Fishing Gazette,' I am indebted to the courtesy of that 

 gentleman, as also for the diagram of the ladder. 



Dr. Nowicki says : 'At Kurczyn, on the river Poprad, in 

 Hungary, there is a high weir which prevents the salmon getting 

 up to the spawning ground, and has caused a falling off in the 

 number of salmon. 



' It was therefore decided in connection with the attempt 

 which was being made at the time to increase the salmon i:. 

 the Weichsel district, to open up the Poprad river again to 

 salmon. Count William Migazzy, President of the Upper 

 Hungarian Fisheries Society, and to whom the improvement
