254 SALMONIA. [NINTH DAY.

 Gmiinden, where they are not allowed to fish ; the 

 fish that rose took with much more certainty at 

 Gmiinden than at Ischl. At a time when many 

 flies are on, particularly large ones, a few days of

 between large and small rivers, I may quote the 

 Yockla and the Agger in Upper Austria. The 

 first of these rivers, when I fished in it in 1818, 

 was full of trout and grayling, and I believe I was 

 the first person, for at least many years, that had
