AMONG those many creatures which know our fields and forests for their homes, is the little garter snake; or, as naturalists would have us dub him, Eutænia sirtalis. If one will but overcome a deep-rooted antipathy to crawling things, and will exchange the city's heat and turmoil for a few weeks of outing in the pure air of our sweet-scented fields, and make our little friend's acquaintance, much that the observer will not willingly forget will be his reward. When the snake is full grown, it is usually a little less than three feet long. The color is very variable, the usual body hues being brownish olive, sometimes with darker patches upon the sides, and generally there is a lighter yellowish streak down the middle of the back.

All snakes crawl by side twists, and not by up and down undulations. They move themselves along by taking advantage of the friction between the sharp edges of the abdominal plates and the ground. The numerous ribs which can be moved forward and backward, as well as up and down, aid them greatly in their progress; and all the movements are performed with such gliding grace that one imagines the serpent to be impelled onward by some hidden, mysterious force.

The garter snake is an excellent swimmer, making rapid progress through the water by means of a rhythmical sinusoidal movement of the submerged body, the little head being always just above the surface. It is a lazy creature, possessed of little desire to see the world, for it rarely wanders far from the place of its birth, as long as food remains abundant. It loves the sunny borders of swamps and ponds, where frogs and earthworms abound, and where it may bask ex-
