"Come down to the corner and I'll show you," said the agent.
"But I can't leave the team," said Bob.
"Oh, I'll take care of the team," said the banker laughing. "You go down and operate the plow."
Handing the lines over to the banker, Bob hurried after the agent, who was racing down the field so as to catch up to the tractor before it reached the corner. Then he stopped the machine until Bob came up. "Now, this is how it's done, Bob. You see this self-steering device down here in the furrow. Well, I set this lever and clamp it over fast and this self-steering device rubs along the edge of the furrow and keeps the plow following the furrow. In big fields in the West, where there's plenty of room and the ground is comparatively level, we always plow around a circle. There's where we use our big fellers," he said smiling. "Fourteen plows in a gang and one man can operate all of them at once."
"You don't mean it," said Bob. "Three or four plows going at once, and each one plowing fourteen furrows. Why, you would plow a field like this in less than a day."
"Less than a day," said the agent. "How long will it take you to finish this field with your team, Bob?"

"Well, I expect to get through by noon on Saturday," he replied.
"Well, what do you say if we finish it up by six o'clock tonight?"
"But you couldn't do that, Mr. Patterson!"
