"An electric locomotive that can make two miles a minute over a properly ballasted roadbed might not be an impossibility," said Mr. Barton Swift ruminatively. "It is one of those things that are coming," and he flashed his son, Tom Swift, a knowing smile. It had been a topic of conversation between them before the visitor from the West had been seated before the library fire and had sampled one of the elder Swift's good cigars. "It is not only a future possibility," said the latter gentleman, shrugging his shoulders. "As far as the Hendrickton and Pas Alos Railroad Company goes, a two mile a minute gait-not alone on a level track but through the Pas Alos Range-is an immediate necessity. It's got to be done now, or our stock will be selling on the curb for about two cents a share." "You do not mean just that, do you, Mr. Bartholomew?" asked Tom Swift earnestly, and staring at the big-little man before the fire.
