done between the 29th April and 4th May, but nothing was ob- 

 served contradictory of the remarks already made. In the Yar- 

 row river, which we fished, as differing from those already ex- 

 amined in the circumstances of arising as a uniformly large 

 river from a lake of considerable magnitude, a few smolts were 

 taken in the river shortly after its quitting the lake. The fry 

 was rather scarce, and trout still more so ; the fry were scarcely 

 the size of those taken near the sources of the northern streams 

 fourteen days before. 



In the streams which join the Teviot, and more especially 

 the Kale, an admirable trouting and salmon stream, the fry 

 abounded to a very great extent, and were collecting in mill-dam 

 heads preparatory to quitting the river. 



Previous to the 2d May the fry were found to have quitted 

 the College Water, which rises near the base of the highest 

 Cheviot ; but fry still about the same size, i, e. from seven to nine 

 inches, abounded in the first pool of the Glen, a name which the 

 College Water assumes on its joining the Beaumont. This pool 

 was formed by a mill-dam head : the young smolt were found in 

 this dam-head in vast abundance. At Horncliffe on the 4th 

 May, the Tweed was reported to abound with salmon smolts ; 

 but we merely report the fact as it was stated to us by the fish- 

 ermen. We saw none taken in the nets, though our observation 

 as to the management of these nets for many hours was minute 

 and careful. The result of these observations, with the mode of 

 fishing the Tweed by coble-nets, (observations to me unexpected, 

 and leading to the most important results in an economical point 

 of view;, fall to be considered more properly under another sec- 

 tion. 



I have thus described the generation of the smolt in fresh 

 water, near the source of a tributary stream of one of the finest 

 salmon rivers which exists in Britain. Of the further progress of 

 the smolt in its growth from its extreme length, so far as I have
