Joey held back when he reached the hold where the artillery mules were; they were restless and were scuffling and biting in the half darkness. He decided that he had done his duty in bringing the pails of water that far; others could give them to the mules. But a watchful corporal spied him.

“Here, you!” shouted the corporal. “Water them mules.”

But still Joey held back.

“Say, you ain’t afraid of them, are you?” demanded the corporal scornfully.

“Naw,” said Joey, “not exactly, but——”

“Don’t be yella!” shot out the corporal. “Are you a soldier or ain’t you?”

Joey picked up the pails resolutely; decidedly he was a soldier. He shouldered his way in among the mules; they seemed gigantic, grotesque in the dimness. He set down one of the pails. It was then that a mule lashed out with its steel-shod hoof. It hit Joey Pell squarely in the back of the head. Sharply a swift blackness fell on his brain.

At the military hospital in a deserted department store on lower Sixth Avenue, to which they rushed Joey Pell, the doctors said that his skull was crushed and that part of it was pressing on his brain. His regiment sailed without him; but Joey Pell never knew it.

His was a curious case, the doctors said. They were able to relieve some of the pressure on his brain, but not all of it. He continued to exist. But he existed as a vegetable does. The part of his brain that gave him memory did not work at all. He had no past, no yesterdays. Each day when he woke, it was as if he were freshly born. Certain habits remained—eating, dressing, simple motion. But he was quite unsensitive to impressions. Each day they told him his name, and a moment later he forgot it. He never asked how he happened to be there; he never asked about anything; he simply sat in the corner of the private room they had given him, quiet, apathetic.

For two years the brain of Private Joseph Pell lay fallow. His mind simply closed up shop and went on a vacation. So, while he sat there, impervious to anything, in a perfect vacuum, his regiment fought, the Armistice was signed, his regiment returned, there was a triumphal march up Fifth Avenue, the regiment was demobilized, and the great city swallowed it once more. The soldiers who had been clerks returned to their counters, the soldiers who had been truckmen returned to their trucks.
