PRACTICAL FLY-FISHER. 37 



magnificent mansion and grounds well worthy the notice 

 of the traveller. About half a mile below Masham, it 

 receives a tributary from the moors, called the Burn run- 

 ning down Colsterdale, and passing within a short distance 

 of S win ton ; like all the other small streams it contains 

 innumerable small Trout, but is more adapted for min-

 soon after receives the name of the Ouse. 



From the source of this river for the first five or 

 six miles, and on even as far as Aysgarth Force, it pos- 

 sesses little or no interest to the Fly-fisher ; the Trout
