In the neighborhood of New York City one of the earliest frogs is the little brown cricket-frog. Next come the mysterious and shrill-voiced peepers, which make each marshy spot fairly shriek with their high-keyed notes. Peepers are hard to capture, because you can seldom see them. A dip-net run through the water where you have heard peepers will generally reward you with two or three little dusky imps, who, when captured, will sing in your coat-pocket, and the writer has had them sing while imprisoned in his hands. A loud, coarse trill announces the appearance of The Tree-Toad, and this batrachian makes a most interesting addition to the collection. It is said that the tree-toad has the power of changing color, varying from ash-white, dull-gray or a brown to a bright-green hue. You must look for the hermit-frogs or spade-frogs where they hide in holes in the ground, and in the damp wood you can hunt the lean-flanked, beautifully-spotted leopard-frog, his cousin, the pickerel-frog, and the brown wood-frog. The bright-green-tree specimen, known as The Anderson Frog, is considered by frog-hunters as a great prize, and specimens can only be captured at rare intervals. When you secure a rare frog do not put him in the same place with larger frogs, for the latter will swallow their smaller companions the first time they feel hungry. The Frog Has Teeth. Put your finger in a frog’s mouth and you can distinctly feel a number of fine, sharp teeth, but if you put your finger in a toad’s mouth you will find no teeth; a frog grabs his prey with his jaws, a toad snips it up with his tongue. Besides the common, funny old hop-toad, there are the Rocky Mountain hop-toads, the Southern hop-toads, and the hop-toads from Northeastern Massachusetts, which differ sufficiently from the common hop-toad to be classed by naturalists as sub-species. Lizards. With the exception of the Gila Monster _there are no poisonous lizards known_, and although many of the little creatures will try to bite you, their teeth are as harmless as so many needle points, and cannot be felt through a glove. Put on an old glove when handling them and you can hold them better; but be very careful and not be rude, or you may be surprised to find you have a stump-tailed lizard in your hand while the caudal appendage will be twisting around in a most astonishing manner at your feet. Many beautiful and interesting lizards may be captured in all parts of the Union.
