Rollo made no mention of this to his comrade. He shut his jaw tightly and endured the pain.
With the utmost caution Kenneth began to wriggle through the narrow tunnel, using one outstretched arm to pull himself over the rough brickwork. The other arm he had to keep close to his side, and even thus it was a tight squeeze. Before his head emerged from the opening he stuck—and stuck fast. He felt as if he were suffocating; he was assailed by the horrible dread that the rubble was slowly yet surely subsiding. He wanted to struggle madly and desperately; to shout for aid. He was momentarily panic-stricken.
Controlling himself by a strong effort, Kenneth ceased to waste his strength in a useless attempt to drag himself from that horrible passage. With the sweat pouring from him he kept quiet, filling his lungs with the cool morning air from without.
"What have you stopped for?" asked Rollo anxiously.
"Can't help it," was the muffled reply. "Give my legs a shove, old man."
This Rollo did effectively by applying his back to the soles of his companion's feet. Keeping absolutely rigid, Kenneth found himself being pushed slowly yet gradually towards freedom. His head emerged—then his shoulders. He could now draw up his left arm and assist in the nerve-racking operation. Wellnigh breathless, bruised and scraped, covered with dirt and dust, and with his clothing rent in several places, he gained the open air.
Kenneth had already had sufficient military experience to learn the value of concealment. Without attempting to stand he made a careful survey of his surroundings. He was in a bowl-like depression enclosed on all sides by irregular hummocks of pulverized brickwork, tiles, and charred timbers.
With a sigh of relief the lad realized that there were no Germans in sight. The attacking party had not thought fit to leave a picket in charge of the ruins of the farm-house. To all appearances the two comrades were the only living persons for miles around.
"I'll get the rope from the well and give you a pull out," announced Kenneth upon returning to the mouth of the tunnel. "It will be a fairly easy job."
"Don't be long, then," said Rollo anxiously.
