"I suppose I should have tested all those pipes and valves as soon as I had just a little steam," said the fun-loving Rover. "There is where I wasn't a good engineer. Well, one thing is certain, nothing gave way but the single pipe."

"And that could happen on any steamer," answered Dick. "Any engine is liable to a breakdown of this kind. The question is, Are we machinists enough to repair the break? If we are not, then we'll have to let the steam power go and hoist some sails."

"Oh, that would be slow work!" cried Sam. "Let us try to fix the pipe. I saw some extra pieces in the tool room. Maybe one of them will fit."

With the engine room cleared of steam they inspected the split pipe. It was a piece exactly two feet long, and they looked over the pieces in the tool room and found one just half an inch shorter.

"I think that will do," said Dick. "We won't be able to couple it on quite so tightly as the other was but we can pack it well, and I guess it will last till we reach some port."

The tool room was supplied with the necessary wrenches and all of the boys spent two hours in fitting in the new piece of pipe. Then they inspected the other pipes and the engine, but everything appeared to be in first-class shape.

The fire had been allowed to die down while the repairs were going on, and was not started up again until the work had been completed.

"Say, don't I look like a nigger?" demanded Tom, as he put down some tools. "If I don't, I feel black from head to foot."

"You are certainly pretty grimy," answered Sam, with a laugh. "But
I am that myself."

"We'll all have to go in for a good wash," said Dick.
