THE SNAKES 337 



We stopped to rest and enjoy our pipes before start- 

 ing back: for there is always especial enjoyment about 

 tobacco after good work is done. Our rest was cut 

 short, however; we had barely settled down when the 

 swamp grew hazy. This was a hint for quick return. 

 The miasma of the Southern lowgrounds is far from

The colored boy was waiting our return; we found 

 him not at all inclined to enter into our enthusiasm about

The big Moccasin was shipped North. Occupying a

 stripe beginning at the snout, passing backward over the 

 eye and ending at the back of the head ; beneath this, also 

 beginning at the snout, is a broader stripe extending 

 along the upper lip plates, thence backward to the angle 

 of the mouth and to the neck. An old specimen from
