The afternoon began to slip by. It was considerably after three o’clock when Joe thrust his head up through the hatchway to say:

“Captain, if you’ll be satisfied to go at slow speed, I think we can make a start now.”

“Then start her, and keep to whatever speed your judgment decides upon,” Tom replied. Making his way aft he informed Judge Swan.

“I am delighted to hear it, of course,” replied that gentleman. “I must, however, give you credit for commanding a boat aboard which a very pleasant day of idleness can be enjoyed.”

The “Meteor” was soon going at a speed that seemed lame and halting for her. She made the harbor at Nantucket, however, at 4.20, and landed her distinguished passenger. Judge Swan shook hands with all three boys, thanking them for his pleasant day.

Knowing that Mr. Dunstan was not at Wood’s Hole, Tom decided to make the run straight to the home pier. Leaving Jed at the wheel, after they were out of the harbor, the young skipper went below.

“Joe,” he asked soon, “what was wrong with the engine?”

“The vaporizer,” Joe replied briefly.

“What ailed it?”

“Why, you see,” Dawson replied calmly, “after the speed stopped I disconnected the vaporizer and put it in one of the lockers. Then, somehow, I forgot all about that vaporizer for some hours. When I thought of it I got it out of the locker, wiped it off on some waste, connected it again—and then the engine began to behave fairly well.”
