48 THE VALE OF GALA. 



beautifully formed little eggs of a blackish colour. 

 Thus, is renewed the process of the caddis worm 

 to the creeper, then to the stone or May fly, 

 for next season. What a wonderful and beauti- 

 ful process of nature do we behold here, every 

 way deserving the study of the naturalist ; life 

 by gradual stages, going on and renewing itself, 

 and creating and renewing food for the inhabi- 

 ters of the streams. For, be it observed, that 

 just in proportion as food is found, will we find 

 fish in the rivers ; and, according to the size of, 

 or the volume of water which fills their bed, will 

 fish, in a general way, be found small or great. 

 When this fly, then, comes on the water, for the 

 first two or three days you will almost always 

 get large trout, and they much prefer the female 

 fly to the male, afterwards, the small fry getting 

 knowing, begin to seize it also, and this I have 

 found over and over again. I suppose trout of 

 about Ib. have not courage to seize so large a 

 prey, or, perhaps, never before saw these lady 

 queens on the water. The tackle for these flies 

 is just like that for minnow, only made of trout 

 fly hooks of the round bend and the smallest 

 size, tied thus, on the finest gut and darkish 

 coloured.
