I recently rambled for half a night over acres of wild marsh, and, while I often wished myself at home or that I could grasp the arm of a friend, yet am heartily glad, now that it is over, that I undertook to trespass upon the haunts of owls, frogs, bitterns, and a host of minor creatures. But let me be more explicit, and a word further concerning frogs. In the tide marshes, where the shallow water has been warmed by the noonday sun, the pretty little _hylodes_ were holding high carnival. I strolled leisurely, at this stage of my ramble, to the water’s edge, but only to find that the creatures could only be heard, not seen; unless, indeed, the trembling specks upon the glimmering pools, which faded out at my approach, were they. The piercing shrillness of their united songs was something wonderful. It was not so much a chorus as the wildest orgies of Lilliputian fifers. At times the song of this same frog is the sharp clicking of a castanet, hence their name in zoölogy, _Acris crepitans_, but none were crepitating that night. Yesterday I waded into a wet meadow and crouched upon a projecting hassock. Thousands of the fifing frogs were about me, but I could see none. I long sat there, hoping that my patience would be rewarded in time, and so it was. At last one came cautiously from its hiding-place in the submerged grass, thrusting but its head above the water’s surface, and scanned closely its surroundings. It eyed me most suspiciously, and then slowly crawled out upon outreaching grass until quite above the water. It seemed very long before it was suited to its perch but when comfortably fixed, appeared to gulp in a great mouthful of air; in fact, must have done so, for immediately an enormous globular sac formed beneath its lower jaw. The sunlight being favorable, I could see that the sac contained about two drops of water. Then the fifing commenced. The motion of the mouth was too slight to be detected, but the membranous globe decreased or increased with each utterance. At no time did it wholly disappear. Noting so much, I then moved slightly to attract the creature’s attention. Immediately it ceased fifing, but the sac remained slightly diminished in size. As I was again perfectly quiet, its confidence returned, and the shrill monotonous “peep!” was resumed, but pitched in even a higher key, as though to make good the loss of time my slight interference had caused.
