NINTH DAT.] DIFFERENCE OF RIVERS. 255 



fished in the same places, but with a very different 

 result; I caught only half a dozen large fish: the 

 third morning, going over the same ground, I had 

 great difficulty even to get a brace of fish for my 

 dinner, and those, as well as I recollect, I caught by 

 throwing in places which had not been fished before. 

 I ought to mention, that the space of water where 

 this experiment was made did not exceed half a mile 

 in length. I shall now speak of the Agger, which is 

 a much larger and deeper river than the Vockla, and 

 cannot be commanded in any part by a double-handed 

 rod, being at least from forty to sixty yards across. 

 The first time I fished this river, I had the same kind 

 of sport as in the Yockla ; the second day, under the 

 same favourable circumstances, there were fewer rises 

 than on the first day, but still sufficient to give good 

 sport; and it was the fourth day before it became 

 difficult to catch a good dish of fish, and necessary to 

 seek new water. The greater depth of the water, and 

 the change of place of the fish, particularly the graj- 

 ling, explain this, to say nothing of the greater num- 

 ber of fish which the larger river contained. I am, 

 of course, speaking of one of the best periods of fly- 

 fishing, when many large flies, of which imitations are 

 easily found, have been on the water. In spring (a 

 bad season for fly-fishing in high Alpine countries) I 

 have thrown great varieties of flies on these two
