As to the use of such lights to a bird there has been much conjecture; but it is thought that it may be a lure to attract fishes. It is well known that fishes and various marine animals are attracted by light, and a heron standing motionless in the water, the light from its breast, if equal to two candles, would be plainly seen for a considerable distance by various kinds of fishes, which would undoubtedly approach within reach of the eagle eye and sharp bill of the heron and so fall victims to their curiosity. If this is a true solving of the mystery it is one of the most remarkable provisions of nature. There is hardly a group of animals that does not include some light-givers of great beauty; but it is not generally known that some of the higher animals also produce light at times. Renninger, the naturalist, whose studies and observations of Paraguay are well known, tells a most remarkable story of his experience with the monkey known as _Nyctipithithecus trivigatus_. He was in complete darkness when he observed the phenomenon, which was a phosphorescent light gleaming from the eyes of the animal; not the light which appears in the eye of the cat, but shafts of phosphorescent light which were not only distinctly visible, but illumined objects a distance of six inches from the animal's eyes. The subject is an interesting one and research among the various phenomena disclosed by naturalists may discover many other animals capable of strange illuminations. THE PINK HOUSE IN THE APPLE TREE. NELLY HART WOODWORTH. Not the least interesting of my summer neighbors is a Quaker family named Chebec, the least fly-catchers. They are little people, else they would not be least fly-catchers, plainly dressed, with olive shoulder-capes lined with yellow, wings finely barred with black and white and heads dark and mousy. The large eyes, circled with white, are as full of expression as a thrush's. What is lacking in song is made up in an energy decidedly muscular, the originality of the note _chebec_, uttered with a jerk of the head or a launch into the air after some passing insect, never being confused with other bird voices.
