ball will curve toward W in the path of the dotted line. Now, if he will look in the story of "How Science Won the Game," where the base-ball editor shows the boys how to hold and how to throw the ball to make the different curves, he will find that when he throws the ball so that it whirls as shown in diagram, it will curve toward P, a direction entirely opposite from the one he designates. And any curve-pitcher will tell him the same. When I first read his explanation, I thought it was all right, for it looks quite reasonable, but upon second thoughts, I saw it was wrong, and to make sure, I took a ball and tried it. The only way I can get around his explanation (aside from actual fact) is this: The point B, as he clearly shows, is moving faster than D, and so the ball, if the friction of the air is taken away, will naturally curve toward the side D or point P. Now, the question is, Will the friction of the air be enough greater on the side B to overcome the difference in the motions of the two sides? If it is, the ball must move in a straight line, but as it curves toward the side D, we must conclude that it is not, and that the friction of the air tends more to hinder than to help the ball to curve. I really believe that if it could be tried, a person could make a ball curve in a vacuum more easily than we can make it curve in the air. Trusting to hear more upon this subject, I remain, sincerely yours, "A CURVER." * * * * * FREMONT, NEB. DEAR ST. NICHOLAS: I have never written to you before, but I think perhaps you will publish this one letter. I hope you will publish it, as I have never yet had anything of mine published. I like the story entitled, "How Science Won the Game." Although I am but thirteen years old I think I can pitch a curve. I go to the Fremont Normal School and like it very much. I am going to have the 1884 and 1885 ST. NICHOLAS bound next week. I think you have a very entertaining magazine, and I think the pictures are very nice. I have the magazine for a Christmas present every year. I have taken ST. NICHOLAS three years and I hope I may always take it. Papa says he doesn't think you will publish this, but I
