He half expected a rebuke, and waited a moment with becoming humility. When it did not come, he swung himself into the seat behind her and held his peace until she spoke again. That was five full minutes afterward. For that length of time Gertrude was crushed under an avalanche of new sensations. The last switch-light in the Carvalho yards had flashed to the rear, and the 926 was quickening her speed with sharp little forward lunges under Maclure's skilful goading. The dizzying procession of grayish-white telegraph-poles hurling itself past the cab windows; the thousand clangorous voices of the great machine; the intermittent glare from the fire-box door, alternating with the fiery shower of sparks pouring from the smoke-stack—it was a bit of pandemonium detached and dashing through space, and she sat cowed and stunned by the rush and the uproar. But presently the warm wine of excitement began to quicken her heart-beats.
"Isn't it glorious!" she exclaimed, trying to look back at him.
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.
