on shares, sawing up the smaller trees into cord wood. He had started in well enough, cutting down considerable timber, for the colored man was a willing worker, but when he tried to start his mill he met with trouble.
"I counted on Boomerang helpin' me," he said to Tom, "All he has to do is walk on dat treadmill, an' keep goin'. Dat makes de saw go 'round, an' I saws de wood. But de trouble am dat I can't git Boomerang to move. I done tried ebery means I knows on, an' he won't go. I talked kind to him, an' I talked harsh. I done beat him wif a club, an' I rub his ears soft laik, an' he allers did laik dat, but he won't go. I fed him on carrots an' I gib him sugar, an' I eben starve him, but he won't go. Heah I been tryin' fo' three days now t' git him started, an' not a stick hah I sawed. De man what I'm wukin' wif on shares he git mad, an' he say ef I doan't saw wood pretty soon he gwine t' git annuder mill heah. Now I axes yo' fair, Mistah Swift, ain't I got lots ob trouble?"
"You certainly seem to have," agreed Tom. "But why is Boomerang so obstinate? Usually on a treadmill a horse or a mule has to work whether they like it or not. If they don't keep moving the platform slides out from under them, and they come up against the back bar."
