THE SMOOTH SNAKE. 57 



throat to the snout of the lizard, by slow and almost 

 imperceptible degrees. When once it has the lizard's 

 head fairly in its jaws the process of swallowing is 

 rapid, and the strong protests of the victim are wholly 

 unavailing, as the snake with its tail knotted round 

 the grass is able to overcome all resistance. In this
