66 A RIVER OF NORWAY 



in our ladder here. Mr. Scott gives some par- 

 ticulars and illustrations of different ladders 

 in America and elsewhere. Perhaps the most 

 interesting is the well-known salmon pass at 

 Ballisodare, in the west of Ireland. 



An article entitled " Salmon Passes," by 

 A. F. Bruce, A.M.I.C.E., may be found in 

 the Transactions of the Civil and Mechanical 

 Engineers Society, 1887-88, and should be con- 

 sulted by any one anxious to ascertain the 

 conditions and cost of a successful ladder. 



If "whoever could make two ears of corn, 

 or two blades of grass, to grow upon a spot 

 of ground where only one grew before" would 

 deserve well of mankind, then no less merito- 

 rious is the man who has peopled a useless river 

 with the noble race of salmon. To the enter- 

 prise and ingenuity of the Irishman who planned 

 and built it, this ladder of the river Gaula, in 

 Norway, is a lasting memorial.
