158 THE SALMON.

 caught, but in what it stopped, doing even more indeed 

 in the way of obstruction than of destruction. Never- 

 theless, these engines had existed from time immemorial, 

 and it was a strong measure to propose their abolition by 

 means of a private Bill. It is true that the proposal was 

 accompanied by another, assented to only by a majority 

 of those concerned, and which, if the division into upper 

 and lower proprietors had been complete as to interests, 

 must have been reckoned as more than a quid pro quo.

 yards into the river, and causing an eddy or "slack-

 enter and rest, especially during the nights when the 

 river is in travelling condition ; and a cairn-net is or

 jection, and then allowed to swing down with the stream, 

 so forming a barrier parallel between the eddy and the 

 main current, and having a good chance of intercepting 

 all fish that turned to pass outward from their resting- 

 place. Of these nets there were several hundreds upon 

 the Tweed ; they were increasable to any extent ; and on

 fish than were taken with the rod. All this the middle 

 and upper proprietors, or the majority of them, ofiered 

 to give up ; in other words, to give up perhaps one-half 

 of the fish they then killed. This proposal, of course, 

 put two powerful arguments into the hands of the upper 

 proprietors ; that they were applying to their own fixed
