The experience of one young man may be cited to demonstrate how the advantages offered by the museum are put to definite use, while friendly relations continue for a period of years. When quite a small boy, a frequent visitor became interested in collecting butterflies and moths, learning how to mount them carefully, and using our books to help identify his finds. As he grew older, he commenced experimenting in a small way in wireless telegraphy, inviting the members of the staff, separately, to go to the basement and listen to the clicking of his little instrument, which was the beginning of successful work in that direction. Throughout his high school course he continued to experiment along wireless lines, doing very creditable work. Upon his graduation, he received an appointment as wireless operator on a steamer. In this capacity he has visited several of the Southern states, Porto Rico, Venezuela, and portions of Europe. He has improved his opportunities for collecting while on his various trips, as a creditable little exhibit, called the "Austen M. Curtis Collection of Butterflies and Moths" in the Children's Museum, will testify. Some definite advantages gained in another field are worthy of mention. Last summer one of the high school boys commenced during the vacation to read all he could about astronomy; as the summer advanced, another boy became interested in the subject also, especially in the study of the constellations. Diagrams and star maps were carefully made and the names of all the important stars noted. In the fall a little club of eight or ten boys was formed. The members meet almost every pleasant evening at the home of the founder of the club and make use of two telescopes which have been secured to the roof. (Incidentally, may we add, that one of the boys with considerable pride recently showed the books on astronomy in the library to his aunt who was visiting from another city.) No astronomy is at present included in the public school course, with the exception of a little elementary study in the grammar school, so that an opportunity is here provided to supplement school work. Children frequently make long visits, sometimes spending the greater part of a day, and bringing their luncheon with them to eat in the park. Sometimes whole families come together, father or mother, or both, accompanying the children. Frequently the little "mother" of the family who is having temporary care of four or five little ones, is not much larger than her little charges, and yet is anxious to read some of the books. Under such conditions, when the little folks become too restless to remain longer in the library or museum, the privilege of reading in the park is occasionally permitted, the book being returned to the library before leaving for their homes.
