wheel that went ahead of the tractor in the furrow he had made. Now the guide led the tractor around in a spiral that got narrower and narrower until at last it stopped in the center of the plowed field. Another
Texan, with a bigger field and more machines, had a larger idea. He set three tractors loose without drivers, one behind the other. Away they went, round and round. If one traveled too fast and caught up with the one ahead, they stopped. The only work he had to do was go out and start them up again!
There have even been experiments in guiding plows by remote control radio, the way airplanes can be guided. The farmer just sits under a tree and pushes buttons in a control box.
COTTON MEANS HARD WORK
Cotton is a crop that has always taken an enormous amount of work. Even after cultivating machines were invented, men had to go through the fields twice every year and hoe out weeds around the plants by hand. One farmer rigged up a contraption that made hoeing easier. He hitched an air compressor to his tractor and ran hoses from the compressor to four special hoes. Then the escaping air jiggled the hoes in the men’s hands and saved the work of swinging them up and down.
