 been hitherto supposed to be confined. Inl862j however, 

 the author caught such a Trout with the fly in a moun- 

 tain-tarn of the same county, called Roy, or Roi, from 

 which the picturesque little salmon-river so named takes its 

 source. The elevation of the loch above the sea-level is 

 considerable, and its appearance striking, as it is situated 

 directly below an almost perpendicular cliff, at the base 

 of which it forms a sort of lynn or caldron. In some parts 

 it is very shallow, but in others the water is black, and ap-

 edge of the declivity between the two is bordered, far out 

 in the pool, by a semicircular sweep of bulrushes cut as 

 sharply as if with a knife.
