MATHEMATICAL ANGLING. 153

 not easily explained in writing, nor. I believe, in con- 

 versation, as will appear from the following example. 

 A friend of mine went with two companions to fish in 

 the river Mora, on the coast of Inverness-shire. One of 

 these two comrades was a young Oxonian, and a novice ; 

 the other was an experienced fisherman. They were 

 all three in one of those Highland shielings, redolent of 

 peat smoke and whisky, which is absolute luxury to 

 a thorough-bred sportsman, as being in keeping and

 was an excellent person, but, as I have hinted, knew 

 nothing upon earth about salmon fishing ; so Mr. E. 

 C, who was an adept in the said art, set about in- 

 structing him by word of mouth. The third person of 

 the party happened not to coincide with the excellence

 unless your fly was at right angles to your rod. This 

 seemed not at all to be comprehended ; and after a little 

 arguing, the said oracle, by way of illustration, took a 

 stick, tied his handkerchief to it, and gave a few
