The reptile book; a comprehensive popularised work on the structure and habits of the turtles, tortoises, crocodilians, lizards and snakes which inhabit the United States and northern Mexico . HEAD OF RATTLESNAKE XVhen the jaws are closed the fangs fold back against the roof of the mouth. Theyare exactly like the hypodermic needle—having an elongated orifice at their tip forthe ejection of venom. The opening near the front of the lower jaw shows the locationof the tongue-sheath. Thus it should be understood that the forked tongue is not asting or in any way connected with the poison apparatus.

SKULL OF A PIT VIPER, SHOWING DEVELOPING PANTOSThe illustration shows how fangs are constantly developing to take the place of the functional pair The Moccasins hardy, thriving for years in a captive state and breeding regularlyif maintained under the proper conditions. In the lowgrounds along the Savannah River the writerhas found these serpents to be very common. They do notfrequent the main body of water in any numbers, but are abun-dant in the adjoining swamps into which the river backs upduring the heavy rains. In these swamps, as the river recedes,the water is left in numerous pools, entrapping large numbersof fish. Thus are the Cotton-mouths found, and in com-pany with various species of harmless Water Snakes. Theyare commonly observed on the branches of bushes and treesthat overhang the water, and if escape from danger be possiblethey quickly drop into the water, where they swim beneath thesurface for some distance to emerge in some sheltered situation—among reeds or aquatic
