turning it to the light.

"Tell me now, lad," he said quietly, "did ye or did ye no ha' the
toothache?"

"It's better now," sullenly.

"Did ye or did ye no?"

"No."

The Chief turned the boy about and pushed him through the doorway
into outer darkness. He said nothing. Down to his very depths he was
hurt. To have lost the game was something; but it was more than
that. Had he been a man of words he might have said that once again
a creature he loved had turned on him to his injury. Being a Scot
and a man of few words he merely said he was damned, and crawled
back into bed.

The game? Well, that was simple enough. Directly over his pillow, in
the white-painted airtrunk, was a brass plate, fastened with four
screws. In case of anything wrong with the ventilator the plate
could be taken off for purposes of investigation.

The Chief's scheme had been simplicity itself--so easy that the
Seconds, searching for concealed wires and hidden alarm bells, had
never thought of it. On nights when the air must be pumped, and
officious Seconds were only waiting the Chief's first sleep to shut
off steam and turn it back to the main engines, the Chief unlocked
the bolted drawer in his desk. First he took out the woman's picture
and gazed at it; quite frequently he read the words on the
back--written out of a sore heart, be sure. And then he took out
the cigar-box lid.

When he had unscrewed the brass plate over his head he replaced it
with the lid of the cigar-box. So long as the pumps in the engine
room kept the air moving, the lid stayed up by suction.

When the air stopped the lid fell down on his head; he roused enough
to press a signal button and, as the air started viciously, to
replace the lid. Then, off to the sleep of the just and the crafty
again. And so on _ad infinitum_.

Of course the game was not over because it was discovered and the
lid gone. There would be other lids. But the snap, the joy, was gone
out of it. It would never again be the same, and the worst of all
was the manner of the betrayal.

He slept but little the remainder of the night; and, because unrest
travels best from soul to soul at night, when the crowding emotions
of the day give it place, the woman slept little also. She was
thinking of the entrance to the stokehole, where one crouched under
the bellies of furnaces, and where the engineer on duty stood on a
pile of hot cinders. Toward morning her room grew very close: the
air from th
