"McCready's right," replied the doctor. "Get straws, Lieutenant, and we'll draw."

McCready picked up three bits of grass and held them out.

"The shortest goes on watch," he said. Carnes and the doctor drew, McCready exhibited the remaining bit of grass. It was the shortest of the three. He waited until the next shell burst above them and then stepped out from the shelter.

"I'll relieve you in fifteen minutes," said Carnes as he left.

"Right."

When the lieutenant had left, Dr. Bird removed the gag from Feodrovna's mouth and tried to argue with her, but the Russian girl only glared her hatred and refused to talk other than to abuse him. With a sigh, the doctor gave over his efforts and talked to Carnes. The time passed slowly with a constant rain of shells on the knoll.

"It's time for my relief," said Carnes at length. As he spoke the hail of shells on the knoll ceased.

"What the dickens?" cried the doctor.

He and Carnes jumped from their shelter and ran over the knoll. On the plain a few hundred yards from them, a straggling line of Russians were advancing with fixed bayonets. McCready was nowhere in sight.

"Where the devil is McCready?" cried the doctor. "He must have been killed. Hello, one of the guns is gone, too. There's only a belt and a half of ammunition left. I'll try to break that attack up."
