toward bringing up Chester Williams right;—he's all I can manage just at present,—unless somebody really wants a lift that I can give him."
Bob laughed, and the air cleared up some sat down on the curb and pulled out my compasses. Mother had been showing me something about geometry, evenings, so I knew some little, easy problems. "Come on, Bob," I said, "and see the way my compasses work." He thought I'd given up the argument and was trying to change the subject, so he came and sat down beside me.
I got out some paper and drew some circles and things, and he got awfully interested; and then I started in on a little problem, but I didn't letter the lines. He's got a mighty sharp mind, and he followed what I was trying to do, just as easy as could be, at first; but by and by he got mixed up as to which line I meant, and so I marked one of them x, and another y, and then it went easier, and he got more and more interested.
Then I started another and marked the lines with the same letters, and we worked that one out.
"Gee!" he said, "I'd like a set like that. Let's see if I can work one of those puzzles."
