The whistle blew. Almost immediately, the sound of footsteps broke the silence and the lavatory was filled with hurrying men. Their stay in the room was short, however, as Joe had known it would be. Men leaving for home do not dawdle on the premises. The lavatory was empty again. A period of silence while Joe raised his feet from the floor and braced them on the toilet seat. The entrance door opened. A guard making the departure checkup. Joe held his breath. If the guard came down the line and tried the door, he was finished. But Joe had banked upon human nature. The guard stopped. For a long moment there was no sound and Joe knew the man was bending over to run his eyes down the line of toilets close to the floor. In this manner he could see the floor of every booth. The guard straightened, turned, walked out. The door closed. Silence. Joe's heart swelled with gratitude. He grinned, looking forward with joy to the long night ahead. He found a spot over behind the barrels where the night watchman would have to climb over a lot of equipment in order to find him. He made himself comfortable, practically certain the guard would not do this. He stretched out on the hard floor and recorded the passing of the hours by the number of times the watchman went through. And he was surprised at how fast the time passed. Finally, checking his count carefully, he left his hiding place and tiptoed to the line of lockers. He took the oxygen equipment from the duffel bag after which he hid the bag and the clothing therein behind a wall flange in a far corner. Then he climbed into the barrel at the front end of the packing line. He checked the barrel with a small X, and jockeyed the lid into place. * * * * * Time passed. Nothing happened. He wondered, if he'd missed on the time element. The men should certainly have come to work now. More than once he was tempted to push the barrel lid aside and check the situation. When footsteps sounded, close by, and the lid snapped firmly into place, he was glad he hadn't done so. Good old Nick! When he got back from the Moon, he'd see to it that Nick got credit for his courageous act. Soon the barrel began to move. Joe felt it rise into the air and settle with a thump. Then the motor of a truck roared and Joe knew where he was going. Straight toward Building A and the Moon rocket. There was more movement until finally the barrel was set down for what appeared to be the last time. Joe put the nose-piece of the oxygen tube into place and visualized himself safe and snug in a storage room of the rocket. He closed his eyes and went peacefully to sleep. He slept a long time, to be awakened by a crushing--a wrenching--that all but drove his head down into his spine. The pain brought him sharply alert. He knew instantly what had happened. _Blast-off._ He braced himself against the sides of the barrel, and gritted his teeth.
