I know one case where an engineer _did_ go mad, remarked a superintendent.

He was one of our most experienced men, and had held the throttle for years on the fastest trains. Then, one Sunday, for no reason at all, he went to the round-house, got out the 'pony' locomotive--that's the one fixed up with a little parlor over the boiler, and easy-chairs and polished wood--it makes a pretty observation-car for big officials. Well, he got her out and started lickety-split up the main line, running wild and without orders. He stopped at Mott Haven, and told the men he wanted the 'pony' rebuilt and silver-plated--crazy as a loon, you see. Yes, he's in the asylum now, poor fellow; that was his last run.
