80 EPPING FOREST. REPTILES. The Common Snake and the Viper are found in the driest parts of the Forest. The former has yellow markings and a scaly appearance, and grows sometimes to three feet in length. The viper is of a dull brown throughout. The Slow Worm, which is quite harmless, is not uncom- mon. It is of a bronzy colour, and about twelve inches long. It is much to be hoped that these reptiles will not be exterminated. The first and last are perfectly harmless. The viper, though its bite would be inconvenient, and possibly dangerous, will not use its fangs unless attacked.
