Mary brought a portable typewriter from home and spent part of the afternoon banging away at what seemed to me, since I use two "What would you think," I asked Marjorie over supper, "if I should undertake to lead a junior achievement group this summer?" She pondered it while she went to JUNIOR ACHIEVEMENT BY WILLIAM LEE tasty, I might add. "Why, Donald," she said, "it could be quite interesting, if I understand what a junior achievement group is. "Goodness." I protested, "it's been twenty-five years since my last course in chemistry. Perhaps if I saw the 20% solution." He gave me a singularly adult some of the children in the lower formula—." to the office today, and told me that I should explain, perhaps, that I teach a course in general science in need adult guidance of course, and and another in general physics in the Senior High School. It's a privilege which I'm sure many educators must ILLUSTRATED BY SCHOENHERR new school is a fine one, and our academic standards are high. On the other hand, the fathers of most of my students work for the Commission and a constant awareness of the Commission and its work pervades the town. It is an uneasy privilege then, at least sometimes, to teach my old-fashioned brand of science to these children of a new age. "What does a junior achievement group do?" "It has the purpose," I told her, "of teaching the members something about commerce and industry. They manufacture simple compositions "Well, now," I demanded, in my best classroom voice. "What is all themselves. which are available for later educational expenses." "Gracious, you wouldn't have to this?" "Of course not. I'd just tell the kids how to do it."

It was rather regrettable that, after the seemed to be elected. "Well, Mr. Henderson, a junior achievement group is a bunch of kids who get together to manufacture and said Hilary. "We'll need some money to do the things we want to do later." "And what sort of things would The usual products, of course, with these junior achievement efforts, are chemical specialties that can be made safely and that people will buy and use without misgivings—solvent to free up rusty bolts, cleaner to remove road tar, mechanic's hand soap—that sort of thing. Mr. McCormack had told me, though, that I might find these youngsters a bit more ambitious. much of the time they seem to have little interest in their studies. The junior achievement idea has sparked their imaginations. Maybe it'll be just what they need." "Exactly," he broke in, "we guessed in the electronics field. A hi-fi sub-assembly of some kind."

If we should keep the achievement group going for several summers, it might be possible later on to carry out a Dr. Matlack's son, aren't you? Been dipping into your father's library?"

On the other hand, they pondered at some length about a "I'll make one tonight," said Doris, "and think about the small end. It'll work out all right."
