“I’ll never trust Dent to do anything for me again,” went on Tom. “I ought to have seen to the oil cups myself, and I will next time. Wait until I catch him!”

“There he goes now!” exclaimed Dick, pointing to a lad crossing a field some distance away. “Shall I run and tell him you want to see him?”

“No, it isn’t worth while,” replied Tom. “Besides, he’s so lazy he wouldn’t walk down here. But I’ll talk to him like a Dutch Uncle when I do see him. Now let’s see if the engine will work. If it does, I’ll give you fellows a ride.”

Once more Tom turned the flywheel over several times, but, though the engine coughed, wheezed and spluttered, as though in apology at having such poor health, it did not start.

“Say, you haven’t got your forward switch on!” suddenly exclaimed Will. “There’s no spark.”

“No wonder!” cried Tom. “I remember now, I had it on, and then, as I didn’t want to get a shock when I was cleaning the spark plug, I shut it off. Then I forgot to put it on again. Hop in, and close the switch, Will, and then maybe we can start. I guess most of the oil is out, now.”

The two chums got in the boat, and Will, making his way forward, closed the connection. Then Tom, who had remained near the motor, again turned over the flywheel. This time there was an explosion, and the engine worked rapidly. The propeller churned the water, and the painter strained as the boat moved forward.

“Hurray!” cheered Dick.

“That’s the stuff!” exclaimed Will, at the prospect of a ride.
