The Rubber Snake is a northern species belonging to
the same family as the boas and pythons of the tropical portions of the
New and Old Worlds. It never attains to anywhere near the size of those
better known 'constrictors.' The individual mentioned below is the
largest Rubber Snake we have ever seen. When fully relaxed this example
measured 645 millimeters (25-1/2 inches) from tip of nose to tip of
tail, and its greatest girth was 65 millimeters (2-1/2 inches). Most of
the representatives of this species which we have seen have been less
than 20 inches long.
The one individual noted by us in the Yosemite region
was found October 7, 1914, in a road near Sentinel Bridge. It had been
killed by some workmen who had passed along just previously. It is
deplorable that people should persist in destroying non-poisonous
snakes. The deep-rooted tendency in some human beings for this kind of
reaction toward all snakes seems to operate entirely without
reason. The Rubber Snake is not only harmless, but, for a reptile, it
makes an admirable pet. We have never known of a snake of this species
attempting to bite or to resent handling in any way.
