He picked out the worn screws and bolts and substituted the new ones which he had brought. Then he sorted out the various parts in their proper order, and examined each critically.
"This bit of iron that guides the pressure spring is warped," he remarked. "Did the rake pull hard when the left side was lower than the right?"
"Yes, and squeaked, too."
"Then, that's the cause of it, and all the oil in the world wouldn't help it."
"Can you fix it?" asked the farmer, anxiously.
"I can if I can get a hot fire," replied Jack.
"I'll start it up at once," returned farmer Farrell, and he disappeared into the house.
When he had the fire well under way, Jack heated the part, and gave it the proper shape. Then he put the machine together, adjusted it carefully, and oiled the parts.
"Guess it's all right now," he said, lifting it over.
"We'll soon see," returned the farmer. Going to the barn he brought out one of the horses and hitched him to the machine. Then he mounted the seat and drove up and down the field several times.
