NOTES BY THE WAY 1 15 



voice of the bull - frog, who calls, according to 



the boys, "jug o' rum," "jug o' nun," "pull tin-

 on a light-colored tree, like the beech or soft maple, 

 and darker on the apple, or cedar, or pine. Then 

 it is usually hidden in some cavity or hollow of the 

 tree, when its voice appears to come from the out- 

 side.

 its habits, like the common toad. By day it re- 

 mains motionless and concealed; by night it is as 

 alert and active as an owl, feeding and moving 

 about from tree to tree. I have never known < 'in- 

 to change its position by day, and never knew one
