CROCODILIANS, LIZARDS, AND SNAKES.

fill ill form or movements. She, at times, seems to toy with the male, indisposed to 

 yield to his importunities, though pressed with ardor. To avoid his suit, at times, 

 she "will dart througli grass, among stones, or enter a crevice. Should he be able 

 to reach liis mate while within a hole, he is not slow in bringing her to the surface, 

 again to be repulsed. Upon an unbroken ground the sexual communion is less pro- 

 longed. Here she is unable to free herself from his quick and effectively directed 

 moves. In case she attempts to quit him, a coil is thrown about her body, and his 

 head laid Hat upon her neck, and replaced as promptly as dislodged, evidently in 

 the endeavor to propitiate her. 



The coustricting power of the black snake is not sufficient to cause 

 inconvenience to a man, but might seriously oi)press a child. The pres- 

 sure exercised by a strong individual wound round the arm is sufficient 

 to conii)ress and close the superficial veins, and cause the muscles to 

 ache, but it is easy to unwind the snake with the free hand and arm. 

 The black snake is harmless, and its bite, which it rarely inflicts, only 

 amounts to a serious scratch.
