Leaves of the American White Ash. 45 



same menacing attitude as before described. I now presented 

 him the sugar maple. He lanced in a moment, striking his 

 head into a tuft of the leaves, *< with all the malice of the under 

 fiends,"" and the next moment coiled and lanced again, darting 

 his whole length at each effort with the swiftness of an arrow. 

 After repeating this several times, I again presented him the white 

 ash. He instantly stretched himself out on his back, and writhed 

 his body in the same manner as at the first application. It was 

 then proposed to try what effect might be produced upon his 

 temper and carriage by a little beating with the white ash. This 

 was administered. But instead of arousing him to resentment, it 

 served only to increase his troubles. As the beating grew more 

 severe, the snake frequently stuck his head into the sand as far 

 as he could thrust it, seeming desirous to bore his way into the 

 earth, and rid himself of his qnwelcome visitors. 



Being now convinced that the experiment was a satisfactory 

 one, and fairly conducted on both sides, we deemed it ungene- 

 rous to take his life after he had contributed so much to gratify 

 our curiosity ; and so we took our leave of the rattle-snake, with 

 feelings as friendly at least as those with which we commenced 

 our acquaintance with him, and left him to return at leisure to 

 his den. — Amer, Jmirn. of Science 4r Arts, vol. xxiii. No. 2.

Caho de Gata^ San Pedro, La Carhonera, — In following the 

 volcanic ridge lately alluded to, from its southern extremity at 

 the Cabo de Gata to the village of Carbonera, a few miles be- 

 yond which it terminates towards the N.NE., tertiary beds 

 are first met with at a locality called Roalquilar, where they 

 form a short ridge of considerable elevation, and a few minor 

 hills, composed of horizontal thick strata of quartzose freestone. 

 Near the same locality, which is surrounded by trachytic hills.
