BRANSON : SNAKES OF KANSAS. 397 



three specimens in this laboratory last summer. Birds, toads, 

 lizards, mice, insects and smaller snakes were placed in the 

 cage with them. They paid no attention to the birds, toads, 

 lizards, and insects, but attacked the mice as soon as they saw 

 them. They would attempt to swallow dead mice that were 

 placed in the cage, but always seized them by the middle of 

 of the body. They could not swallow them without beginning 

 at the head, and eventually gave it up. I captured a specimen 

 in Gove county in August, 1893, that had just swallowed a 

 mouse. From these observations I conclude that mice are its 

 principal food. 



This snake is not often found far from water. The ones that 

 I kept in captivity last summer stayed in the water most of the 

 time. One of these snakes molted three, one four and one 

 two times during their five months' captivity. The one that 

 molted four times always became cross just before molting 

 and would strike at me when I attempted to handle him. He 

 did not strike hard enough to do any injury.
