Presently the doctor came out and, taking Peter's arm, led him to the front of the flat. "The child's very ill," he said, "I'm going to send for a trained nurse."

Pat cried his best, but every now and then this would be broken by the fearful cough. It was like the baying of an animal. A spasm from the back room interrupted Dr. Clay. "It almost sounds as if there was another person in that room," he said. "I'm going back."

Peter knew who that thing or person was. He went with Clay and lifted Pat out of his crib and held him in his arms. This gave him a curious feeling that he was doing something; as if he were trying to throw his body between Pat and someone else. In a dim way he felt that he and Pat and the other one, all three, were running down a football field. He must keep close to Pat and block off the tackler.

"Part of my tiredness it goes into your arm." Maria had said that. And now Peter wanted to give something of his own strength to Pat against the fury of the attack. It did not seem fantastic. There was a current in the contact. The man had lied when he said Peter and Maria were one. That couldn't be done. Men and women were grown people, individuals, all finished, but this was only a little person. He was part of Peter. Father and son were one. He was holding Pat so tightly that nobody could take him away. His prayer was all the more fervent from the fact that he did not believe in God. He had to create God. "Don't let him die. Don't let him die." God began to take form in his mind. God was Maria. She was gone and not gone. To her he did not need to make a prayer. "Maria" was enough.

The doorbell rang and Dr. Clay answered it. He brought Miss Haine back. "I guess you know this baby," he said. "We've got to make him well." The nurse spoke to Peter and set about fixing a croup kettle beside the crib. The fumes filled the room. It was a pleasant smell. "Better lay him down in his crib, now," said the Doctor, touching Peter on the shoulder, "so he can get the benefit of this. I think he's a little better already."

Peter knew that he was. Pat was no longer gasping and in a few minutes he was asleep. For a time Peter sat beside the bed. The child's breathing was regular and his cheek was cool to the touch. "Why, he's fine now," Miss Haine told him. "You go to bed. In the morning you won't even know that he's been sick."

There was no trace of the shadow upon Pat next day. Peter was the haggard one. Something had gone out of him during the night as he held Pat in his arms. Father and child were doing as well as could be expected.

CHAPTER XIII

At the age of eleven months and eight days Pat walked for the first time. Peter thought he might have been considerate enough to have chosen a Sunday. His first tooth came on a Sunday, but that wasn't any fun. Besides, it couldn't be tied exactly to some particular day and minute the way that the walking could. Nor was there any gaiety about it. However, Peter did not quite miss the walking for he came in time to see the last couple of hundred yards.

It was a rainy Saturday and Peter happened home early. Kate met him in the hall with a finger at her lips. "He's walking."
