Jack did not stay longer than half an hour, but during that time he went over the whole scheme of building the new iceboat in Toby's shop.

"I've got all the specifications down in black and white, you see, Jack," the other said at the door, "as to what we'll need; and now that you've approved, I shall start right in and order the stuff tomorrow. The sooner we get started the better; though I don't suppose we'll really have much spare time to work at it until after Thanksgiving, and the big game with Harmony is over."

So Jack said goodnight and went out of the front door. Usually he was wont to whistle as he crossed the lots that would serve as a short cut to his own house; but somehow tonight he was busily engaged with his thoughts, and forgot to indulge in this favorite pastime.

It was a moonless night.

The stars shone brightly in the blue dome above, but gave very little light; although it was not really dark anywhere inside the confines of Chester, since the streets were pretty generally illuminated with electricity.

Jack had just started across lots when he made a discovery that aroused his curiosity a little. There was a queer sort of light flickering beyond him. He quickly realized that some person must be walking the same way as he was, and carrying one of those useful little hand-electric torches, which he seemed to be moving this way and that in an erratic fashion.

"Whoever it is," Jack told himself presently, "I do believe he is looking in the grass for something he's lost."

Walking on and a bit faster than the unknown seemed to be going, he soon drew closer, and was able to see that it was a boy who bent over and scrutinized everything upon which the light of his flashlight fell. Once he uttered an exclamation of sudden delight and made a jump forward, only to stop short, and give a doleful grant as though discovering his mistake.

"Oh! how cruel to fool me so," Jack heard him mutter to himself; "only a scrap of waste paper, and I thought I'd found it. Twice now I've gone over the whole lot, and never a trace have I seen. Oh! what shall I do about it? I wish I knew."

Jack by now had recognized the boy as Big Bob Jeffries, the heavy- hitting outfielder of the Chester baseball team, and who was admitted as standing a first-rate chance to be made the sturdy fullback of the new eleven in football.
