HOW TO MAKE TROUT-FISHING 



myriad brooks and burns that seam the land all along the 

 west coast from the Land's End to John o' Groat's, and so 

 down the east coast as far south of the Humber. Nearly every 

 one of these is capable of being engineered into a productive 

 fishery. No rivulet so trivial, provided it is perennial, but 

 can be harnessed to supply a chain of pools of greater or less 

 extent. The resources are here, there, and everywhere, only 

 waiting for development. 



In setting about the construction of a fishery such as this, 

 one cardinal principle must be kept in view. Merely to throw 

 a dam across the main channel of a stream will never give a 

 satisfactory or permanent result. A pool will be created, no 

 doubt, but the process of silting up will begin immediately. 

 In mountainous districts a single winter spate may bring down 

 such an accumulation of grit, gravel, and shingle as will obli- 

 terate the pool altogether. In lowland districts the process 

 is slower, but it is not less sure, sand and mud taking the place 

 of gravel and shingle. 



Instead, therefore, of damming the main channel of the 

 stream, the flow must be diverted so as to run at a higher level 

 than the surface of the proposed pool. In glens the gradient 

 is usually sharp, and in such places a new lade or channel of no 

 great length will have to be cut to convey the main run past 

 the pool, which is fed by a side runner. The number of pools 

 which may be so constructed depends only upon the length 

 of the glen, the nature of its sides, and the enterprise of the 

 ownef of the ground. Of course, if the sides of the glen are 

 rocky, the expense of cutting a new channel for the stream may
