accounts for Hoskins by putting another
German completely out of commission. A prompt return compliment knocked
Jerry's revolver out of his hand. At this juncture Slim played a heroic
part by laying low another German.

Seeing themselves now outnumbered almost two to one--for apparently they
did not know that they had injured Hoskins--the two remaining Boches
took one final, despairing survey of the situation, then turned and
started on a dead run for their own lines.

Lieutenant Mackinson leveled his revolver at them, held it in that
position for a moment, and then--perhaps it was an accident--seemed to
elevate it slightly in the air and fired. Certainly neither German was
hurt by the bullet, although it did seem to add a little to their haste.

"The position is ours," announced the lieutenant exultantly, and then,
suddenly remembering that Frank Hoskins had been hit and that Jerry had
dropped his gun, he inquired: "Hurt badly, Frank? And how about you,
Jerry?"

"Nothing but a scratch," said Frank. "Took me right on the 'crazy bone'
and made me jump for a minute, but it's hardly bleeding now."

"Only hit my gun," announced Jerry, "and I recovered that."

There was no time for further conversation. The Germans had reached
their own lines, and a machine-gun was being trained upon the Americans.
They rushed headlong to the north side of the little mound, and into the
opening of a natural cave.

The earthwork made them as solidly entrenched as though they were behind
their own lines, and only heavy shells could dislodge them. But they had
work to do, and the nature of it required that they do it quickly.

The entrance faced almost directly north and into No Man's Land, so that
the light of an electric flash, such as they all carried, hardly could
attract the attention of either side.

"Joe," said the lieutenant, sizing up the situation, "it is not safe to
leave the enemy unwatched for a single second. I think it would be well
for you to stay on duty outside, while the rest of us rig up the
instrument and begin to unspool the wire. Hoskins, you're hurt, so you
stay here with Joe. But both of you be mighty careful not to expose
yourselves where you'll stop a German bullet."

With Lieutenant Mackinson leading, Jerry just behind him and Slim
bringing up the rear, they crossed the five feet of narrow passageway
back into the natural dungeon.

The lieutenant switched on his light. Involuntarily and with a startled
