No child was found who could be termed a thorough physical degenerate, and the author concludes that the majority of the class of children dealt with are physically fairly average individuals. Busy Birds.--A close observation of a day's work of busy activity, of a day's work of the chipping sparrow hunting and catching insects to feed its young, is recorded by Clarence M. Weed in a Bulletin of the New Hampshire College Agricultural Experiment Station. Mr. Weed began his watch before full daylight in the morning, ten minutes before the bird got off from its nest, and continued it till after dark. During the busy day Mr. Weed says, in his summary, the parent birds made almost two hundred visits to the nest, bringing food nearly every time, though some of the trips seem to have been made to furnish grit for the grinding of the food. There was no long interval when they were not at work, the longest period between visits being twenty-seven minutes. Soft-bodied caterpillars were the most abundant elements of the food, but crickets and crane flies were also seen, and doubtless a great variety of insects were taken, but precise determination of the quality of most of the food brought was of course impossible. The observations were undertaken especially to learn the regularity of the feeding habits of the adult birds. The chipping sparrow is one of the most abundant and familiar of our birds. It seeks its nesting site in the vicinity of houses, and spends most of its time searching for insects in grass lands or cultivated fields and gardens. In New England two broods are usually reared each season. That the young keep the parents busy catching insects and related creatures for their food is shown by the minute record which the author publishes in his paper. The bird deserves all the protection and encouragement that can be given it.
