 with a snap as sharp as that of my lady's Blenheim, 

 disturbed from its fire-rug siesta by the buzzino-

 the winch with my hand, and I very often had the

There is nothing like observation. Let the 

 learner place himself on an elevated spot, and over- 

 look the actions of a brother salmon-fisher. He will 

 see how the cast is performed; he will see the fly 

 alight on the water, and sink a little into it ; he 

 will then see it worked through the water, he 

 will see the exact form it assumes whilst beinsf 

 so worked, and the rate of speed communicated to

 wings and fibres will be nearly always in a state 

 of collapse, and will wonder at the contraction of 

 its size, and he will be amazed at the darting rapi-

 that sharp working of the fly is wrong — unna-
