 What is the most likely cause of the accident that displaced Marjorie and Donald from their home?
SCHOENHERR "What would you think," I asked Marjorie over supper, "if I should undertake to lead a junior achievement group this summer?" "Why, Donald," she said, "it could be quite interesting, if I understand what a junior achievement group is. Some groups have built up tidy little bank accounts which are available for later educational expenses." Marjorie put back her head and laughed, and I was forced to join her, for we both recognize that my understanding and "feel" for commercial matters—if I may use that expression—is almost nonexistent. Back in the old Ridgeville, fifty-odd miles to the south, we had our home almost paid for, when the accident occurred. When Ridgeville moved to its present site, so, of course, did we, which meant starting mortgage payments all over again. This was to be our headquarters and factory for the summer—a roomy unused barn belonging to the parents of one of the group members, Tommy Miller. "The Miller boy and Mary McCready," he had said, "have exceptionally high IQ's—around one forty or one fifty. "You should be able to make ball bearings by molding, then densify them by electroplating." Healthy mice of the right strain," I explained to Tommy, "might be sold to laboratories. "Well, now," I admitted, "the market for red mice might be rather limited. The parents had agreed to underwrite lunches at the barn and Betty Miller philosophically assumed the role of commissary officer. I'd forgotten all about organization, and that, according to all the articles I had perused, is most important to such groups. Peter Cope waved it off by remarking that they'd each do what came naturally. It was Mary, finally, who advanced the thought of kites. Doris added to this that if you could make the discs light enough to float, they might be colored white and spread on the surface of a reservoir to reduce evaporation. These latter ideas had made unknowing use of some basic physics, and I'm afraid I relapsed for a few minutes into the role of teacher and told them a little bit about the laws of radiation and absorption of heat. Four of them were at the barn when I arrived next morning; or rather on the rise of ground just beyond it, and the kite hung motionless and almost out of sight in the pale sky.
