It was no easy matter to take the automobile engine apart, and substitute a new gear for the broken one. It was also found necessary to insert new spark plugs, which had become covered with a coating of carbon; and the cylinders also needed cleaning, while the pistons had to be adjusted.

The afternoon was spent in working at the auto, and by night such good progress had been made that Jerry said by the next evening it would be in shape to start.

“That is if the gang let’s us,” spoke Ned.

“We’ll make a dash for it,” replied Jerry. “We needn’t fear them with the car in good order, for we can leave them behind in less than half an hour. We’ll try to escape to-morrow about midnight.”

“In the meanwhile let’s eat,” suggested Bob, and his cry brought forth the usual chaffing about “Chunky’s” appetite.

Ned started to get supper. He went to the tank of the auto to draw some water for the tea, when he gave a cry of surprise.

“What’s the trouble?” called Jerry.

“The water’s gone!” exclaimed Ned. “That’s a leak in the tank!”

They all rushed to the car. There, on the ground under the reserve tank was a muddy spot, showing where the precious fluid had dripped away. A quick examination showed there was a small hole in the reservoir.
