SNAKES IN MOTION.
A snake moves along the ground by contracting the ribs on one side of his body and separating those on the other side. This forms one curve. Another contraction takes place at the end of tha expanded side, and bends the body in the opposite direction. Thus there is a series of alternate constrictions and spreadings of the numerous ribs throughout the length of the reptile as it lies on the ground. When the snake is in motion some part of the body must secure itself against a rough or projecting surface, from which the forward part can be impelled. Then the forward part takes hold, and the hinder length is dragged to a new position. The row of shields along the snake's belly is very quick in seizing upon the* slightest projection, so that any rough surface affords a good track. lv climbing a tree the snake uses the same process. It must find points of vantage for its curves. It cannot possibly wind itself spirally round a tree.
