"It's more than that," grinned Sammy, handing over the letter for her to read.
Bob took advantage of his mother's absorption in the letter to snatch Sammy's cap and throw it into one of the racks on the other side of the car. But Sammy got back at him by snatching his cap in turn and holding it out of the open window.
"You get that cap of mine back mighty quick, Bob, unless you want me to drop yours alongside the railroad track," threatened Sammy.
Bob's face lengthened.
"Aw, you wouldn't do that, Sammy," he pleaded.
"Wouldn't I?" retorted Sammy. "Just watch me."
Bob hesitated a moment.
"My fingers are getting kind o' cramped," said Sammy, calmly. "The cap may slip out of them any minute."
Bob still hesitated. He hated to eat humble pie.
"You'd better hurry up," warned Sammy. "If I don't get my cap back before we pass the next twenty telegraph poles alongside the track, I feel it in my bones that something's going to happen."
