236 SALMONIA. OI*TH DAY. 



(particularly the caudal fin) often appear worn and 

 broken ; at this season they are usually in constant 

 motion against the stream, and are stopped by no 

 cataract or dam, unless it be many feet in height, and 

 quite inaccessible. In the middle of September I 

 have caught huchos perfectly clean in rapid cool 

 streams, tributary to the Laybach and the Sava 

 rivers; and, from the small development of their 

 generative system at this time, I have no doubt that 

 they spawn in spring. On the 13th of September, 

 1828, I caught, by spinning the dead small fish, 

 three huchos, that had not a single leech upon their 

 bodies, and they were the first fish of the kind I ever 

 saw free from these parasites. 



ORN. I am so much pleased with my good fortune 

 in catching this fish, that I shall try all day to-morrow 

 with the bait, for more of the same kind. 



HAL. You may do so; but many of these fish 

 cannot be caught ; they migrate generally when the 

 water is foul, and, except in the spring and autumn, 

 do not so readily run at the bait. I was once nearly 

 a month seeking for one in rivers in which they are 

 found, between the end of June and that of July, 

 without being able to succeed in even seeing one alive ; 

 and as far as my information goes, the two places 

 where there is most probability of taking them, are at 

 Laybach and Ratisbon, in the tributary streams to the
