practical working conditions, of eighty-five to ninety, or even ninety-five, per cent. The question that now immediately confronts the physicist and engineer, in the great problem of supplying the world with a new ultimate source of power adequate to the present and future de mands, is to put this free, universal, unlimited supply of energy, without any transformation of it, to directly actuating our magneto-electric ma chinery already made. The present methods of obtaining electrical energy from mechanical energy through heat from chemical energy cannot meet the require ments of the present condition, and needs, and intelligence, of the world. The direct application, without any transfor mation, of the magneto-electric energy of solar radiation will mark the next epoch of man’s his tory and create and minister a new age of the world. Two classes of perhaps posssible methods of making this direct application of radiant solar energy, and some experiments begun under one of them, were briefly mentioned. THE POPULAR YOUNG MAN Yes, Charles Dolasfund was a good sort of fel low, and though it might be said that he had not a close friend to his name yet it is none the less true that he had no one to wish him the least mis fortune. A jovial fellow who gave the hardest grind as warm a welcome as the more frequent caller. His room was generally open all hours of the day and night, and call when you would, a crowd of fellows might always be found there. One evening last week I dropped in to have my usual evening chat with him, and luckily found him alone. He was leaning back on his chair, his feet on the window sill, a “Descriptive” up side down on his knees, leisurely puffing at a pipe and watching the smoke curling and floating out the open, window. A far away look was in his eyes, and occasionally a smilS flitted across his THE FREE LANCE. handsome features, so pale and wan from late hours of writing ponies and cramming for the or deals so rapidly approaching. He turned as I approached and 1 noted a troubled expression on his face. Flinging myself into the nearest chair, I soon had him drawn into a conversation. “Chum,” said he, “I’mgoingto let you into the whole affair. I’m in a pretty box now and need your help to get out. You know last Easter vacation I was down home and met a daisy girl, all smiles and dimples, and all that you know. Had a big time with her. Well, before I left I gave her an invite to come over for com mencement, and now I just got a letter saying that she will be over to-morrow.” “Well, you ought to be joyful, I’m thinking,” I put in. “Joyful! Do you know that my paternal ancestor has shut down on the cash and I had to borrow some to see me through the term ? How’s a fellow to have any fun if he has no cash? She must go to the hop of course, must have a few drives too, and then theres the bakery and flowers for the exercises and other items ad-infinitum. I’ll be busted before I begin man. Then where am I to get time to get ready for my examinations? It will be my duty to flunk in Descriptive and History, I suppose, and that means more money,” and he throws his book into the corner of the room as other fellows come in, and cards and -cigarettes are the order of the evening. Well, by hard labor before the rest are up, Charles manages to pass his examinations by the skin of his teeth, and is genuinely . surprised on being told so by his professors. Now, as his father has sent him some money, he must cele brate. Then the young lady appears on the scene his visits to the cottage are suddenly discon tinued. What pleasant moonlight walks they did enjoy that week, and what pleasure those long drives afforded. Then, who but they knew of the pleas ant little secrets which were exchanged upon these occasions, when for the time, all thoughts of ex-
