It is quite possible for two persons to converse in the cab of a flying locomotive, but the factor of distance must be eliminated. Wherefore he bent over her till his mustache brushed the pink ear. "I am glad you like it. Are you still quite comfortable?" "Yes, indeed; thank you. How fast are we going now?" "About twenty-five miles an hour; but we'll double that when Maclure gets her warmed up." "Double it! Why, we seem to be fairly flying now!" "Wait," said Brockway. Maclure was sitting sphynx-like on his box, coming to life now and then to reduce the angle of the reversing-lever, or to increase that of the throttle. The fireman labored steadily, swaying back and forth between the coal-chute and the fire-box door, his close-fitting cap on the back of his head, and Brockway's cigar,—unlighted, in deference to Gertrude,—between his teeth. "What dreadfully hard work it must be to shovel coal that way all night," Gertrude said, following the rhythmic swing of the fireman's sinewy figure with her eyes.

Presently, the laboring engine began to heave and roll like a storm-tossed vessel, and Gertrude was fain to make use of the foot-rest. Being but a novice, she made unskilful work of it; and when her foot slipped for the third time, Brockway took his courage in both hands. "Just lean back and brace yourself
