This multiplied by sixty, to represent an hour, and then by five to get the grand total, in point of time, makes more than three hundred thousand missiles distributed over an area of less than five square miles. Imagine, if you can, what it would mean to have ten of those terrific shrapnel shells explode over every acre in that region. No wonder that human flesh cannot stand that sort of warfare. Slowly the muzzles of the guns were raised higher and higher. In the front, over that broad field, although the sun was shining brightly, yet there was a thick haze. Absolutely nothing could now be seen but the densest smoke, and noises were no longer distinguishable. The boys rushed down to the telephone station. The operator, streaming with perspiration, and with a voice so hoarse that it was scarcely above a whisper, was still taking the messages. "The second line has just been taken. They are rounding up a division beyond the hill. The traverses beyond are filled with Germans, who have not offered any resistance. Prisoners are coming in by the thousands. The railroad has been reached." "Wonderful! wonderful!" shouted the lieutenant in an ecstasy of joy. "I didn't expect that. We have cut into them two miles, at least." The operator held up his hand. "The main defenses on the ridge have just been taken. The reserves have been ordered up to handle the prisoners. Four staff officers have been taken from the tunnel shelters," he said. Every one was in a delirium. Each felt that he had contributed some share to the glorious victory. It was a revelation of the power of the French gunnery, and the wonderful co-operation of the infantry in moving forward in the shelter of the _curtain_, as it has been so aptly termed. Gradually the deafening din ceased and appeared to die away. One gun from each battery still remained on duty, and fired at regular intervals. With field glasses many things could now be distinguished, the important one, and that which most interested the boys, being the immense number of troops moving to and fro and through the fields so lately harrassed by their guns. "Would you like to take a trip across that territory?" asked the lieutenant, as the boys came up. "Indeed, we would," replied Ralph. "It is too late tonight, but we intend to make an inspection tomorrow," he replied. "I promise you shall go along." At supper that night there did not seem to be any extraordinary show of enthusiasm. Probably every one had been surfeited with excitement. "Don't you have a queer feeling in your ears?" said Alfred. "Well, my ears have been humming and buzzing right along. It appears sometimes as though the guns were still going. It seems unnatural to have this quiet," remarked Ralph.
