Driving looked like an easy job, but it was not. It was very tiresome to stand on that small platform all through the long day of the early fall, and on cold November mornings when the cutting wind roared over the plain, sweeping the dust and leaves along the road. It was far pleasanter to sit on the south side of the stack, as Tommy did, and watch the horses go round. It was necessary also for the driver to be a man of good judgment, for the power must be kept just to the right speed, and he should be able to gauge the motion of the cylinder by the pitch of its deep bass hum. There were always three men who went with the machine and were properly "the threshers." One acted as driver; the others were respectively "feeder" and "tender"; one of them fed the grain into the rolling cylinder, while the other, oil-can in hand, "tended" the separator. The feeder's position was the high place to which all boys aspired, and they used to stand in silent admiration watching the easy, powerful swing of David McTurg as he caught the bundles in the crook of his arm, and spread them out into a broad, smooth band upon which the cylinder caught and tore like some insatiate monster, and David was the ideal man in Lincoln's eyes, and to be able to feed a threshing machine, the highest honor in the world. The boy who was chosen to cut bands went to his post like a soldier to dangerous picket duty. Sometimes David would take one of the small boys upon his stand, where he could see the cylinder whiz while flying wheat stung his face. Sometimes the driver would invite Tommy on the power to watch the horses go round, and when he became dizzy often took the youngster in his arms and running out along the moving sweep, threw him with a shout into David's arms. The boys who were just old enough to hold sacks for the measurer, did not enjoy threshing so well, but to Lincoln and his mates it was the keenest joy. They wished it would never end. The wind blew cold and the clouds were flying across the bright blue sky, the straw glistened in the sun, the machine howled, the dust flew, the whip cracked, and the men worked like beavers to get the sheaves to the feeder, and to keep the straw and wheat away from the tail-end of the machine. These fellows, wallowing to their waists in the chaff, did so for the amusement of the boys, and for no other reason.
