species will often leap 5 or 6 feet out of the water, and its habit of jumping over 

 the cork lines of seines has given it the name of " Jumper." 



In cold weather the Bass seeks deep places, often hibernating under rocks, 

 sunken logs and in the mud. Favorite localities are under overhanging and brush- 

 covered banks, in the summer, and among aquatic plants, where the fish lies in wait 

 for its prey. 



The spawning season of the Large-mouthed Bass is about the same as that of the 

 Small-mouthed species, beginning in April and lasting till July. Its eggs are 

 adhesive, sticking to stones during the incubation period, which last from one to 

 two weeks according to the temperature of the water. The young Bass remain in 

 the nest a week or 10 days, and at the age of two weeks will measure about ^ of an 

 inch in length. In suitable waters it is estimated that the Large-mouthed Bass will 

 weigh at the age of three years from 2 pounds to 4 pounds. 



The Oswego Bass is even more destructive to fish than M. doloinicu. It will eat 

 any fish which it can .manage to get into its mouth and will lie on the bottom for 

 days so gorged that it cannot stir. In voracity it is only equaled, but hardly 

 excelled by the Pike. This Bass bears captivity well. (After Eugene Smith.*) 



The young above referred to as coming from Caledonia, N. Y., hibernated and 

 took scarcely any food during the winter, but fed ravenously in spring, summer, and 

 fall. They proved very hardy in captivity.

The Pike Perch belongs to the genus Stizostcdion, which has been distinguished 

 from the Saugers by the structure of its pyloric caeca, which are three in number, 

 nearly equal in size, and about as long as the stomach, and also by the presence of 

 21 soft rays in the second dorsal, while the Saugers have 18. It may be remarked 

 that all of these characters are more or less variable. 



The Pike Perch- has received a great many common names. One of the most 

 unsuitable is " Susquehanna Salmon," which is used in Pennsylvania. In the Eastern
