202 MAKING A FISHERY. 



exhaustive examination was made of all the 

 water meadows, with the result that only one 

 dead trout and one dead pike were found in a 

 stretch of four and half miles of the river. As 

 a confirmation of the theory advanced here that 

 even during a severe flood the tendency of the 

 fish is to work up stream, it may, however, be 

 noted, that on every spawning bed, whether in 

 the river itself or carriers in the upper part 

 of the water, there were found to be more redds 

 than the previous year. This, however, may 

 have been partially accounted for by the exten- 

 sive stocking which had taken place. The 

 bed of the stream, too, was throughout greatly 

 improved in character by the thorough clearing 

 away of mud and refuse, effected by the in- 

 creased stream running over it during the 

 continuance of the flood.

 in every well-regulated fishery. It is mani- 

 festly the case, that in stocking and improving 

 a length of stream, a certain amount of good is 

 bound to accrue to the water immediately 

 above, owing to the increased number of trout 

 working up stream, and to the water below,
