Leo E. Miller, In the Wilds of South America
“ There are two distinct species, namely: the boa-constrictor, or land-snake; and the anaconda, which spends the greater part of its life in and near water. This latter attains the greater length. A fully grown boa-constrictor does not exceed twelve feet in length; ten or eleven feet is the usual size attained. There is a great difference in the tempers of the two species. A boa soon becomes very tame, and in many places the natives keep them running at large in the huts to catch rats. The anaconda is of a restless disposition and easily irritated. ”
