Habits. — The Milk Snake is often accused of sucking 

 the milk from cows, from which fact it takes its common 

 name. In all my experience I have never found anyono 

 who had really seen it done, nor have I myself ever wit- 

 nessed it. While this snake makes its home around spring- 

 houses it does so to be near its food — rats and mice. The 

 Milk Snake is a cannibal, swallowing its own kind and 

 other small serpents and lizards. The first Milk Snake 

 I found was hiding under the loose bark of heavy rotten 

 log. I placed it in my collecting bucket with a lizard, 

 Eumeces fasciatus. On looking into the bucket a little 

 later I found only a small end of the lizard sticking out of 

 the snake's mouth and the wriggling tail, which had been 

 broken off in the struggle, at the bottom of the bucket.
