The captain made two mistakes that day. One was when he thought he was going to make some money by towing a schooner and the other was when he thought he was going to run in again. The tug-boat had not gone ten minutes on her returning course, when suddenly her machinery stopped, and in a few moments the boat turned about and began to roll in the trough of the sea. There was now a good deal of confusion in the engine-room, and there the boys made their way, not without difficulty, for the rolling motion of the boat made it very hard for them to keep their feet. In the engine-room they found the captain, the engineer, and one or two others of the small crew. Something had broken, the boys knew not what, for no one seemed to have time to explain the matter to them. Efforts were being made to repair the injury. There was a great deal of hammering and banging and loud talking, and presently the engine let off the steam from the boiler, which made such a noise it was almost impossible to hear anything that was not shouted into one’s ear. Perceiving that they were in the way, and could find out nothing, and were to be told nothing, the boys prudently retired into the inner cabin. Here Phil and Chap became quite sick. They could stand the pitching and tossing of the boat as she rose over and plunged down the waves, but this rolling motion was too much for them. The two unfortunates crawled into the little bunks in which they had slept the night before, while Phœnix, with an air of brave resignation, braced himself against the cabin-door, and waited to see what would happen next. Nothing seemed to happen next. After awhile the noise of the escaping steam grew less, and then it stopped. The hammering and banging had also ceased, and thinking that everything was all right now, Phœnix went forward to see how things were going on. It was not easy to see much, for the engine-room was lighted only by a hanging lantern, but he met the captain, who informed him that they were in a bad way. One of the connecting-rods had been broken, and as the engine was not stopped soon enough, some other parts of the machinery had been damaged. “We have tried to patch her up,” said the captain, “but it is no go. All we can do is to make everything tight, and lie here until some vessel comes along to give us a tow in. This has been a pretty bad day for us, for we’re not going to take any steamer up the river to-morrow.” “How long do you think you’ll have to stay here?” asked Phœnix. “Don’t know,” answered the captain. “Something may come along pretty soon, and we may not be towed in till morning. But you needn’t be afraid. We’ll make everything tight, and though we may roll and pitch, we won’t take in any water.” “I suppose that vessel with a broken mast couldn’t help us?” said Phœnix. “No,” said the captain, “it is more than she can do to take care of herself, and she is out of sight now, although she isn’t any nearer the Breakwater than we are.”
