Shooting out of a grove, a valley made a channel for sound that brought to our ears the thunder of guns, with firing so rapid that it was like the roll of some cyclopean snare-drum beaten with sticks the size of ship-masts. From the crest of the next hill we had a glimpse of an open sweep of park-like country toward wooded hills. As far as we could see against the background of the foliage which threw it into relief was a continuous cloud of smoke from bursting shells, renewed with fresh, soft, blue puffs as fast as it was dissipated. This, then, was a battle. No soldiers, no guns, in sight; only against masses of autumn green a diaphanous, man-made nimbus which was raining steel hail. Ten miles of this, one would say; and under it lines of men in blue coats and red trousers and green uniforms hugging the earth, as unseen as a battalion of ants at work in the tall grass. Even if a charge swept across a field one would have been able to detect nothing except moving pin-points on a carpet. There was hard fighting; a lot of French and German were being killed in the direction of Compiègne and Noyon to-day. Another dip into another valley and the thir-r-r of a rapid-firer and the muffled firing of a line of infantry were audible. Yes, we were getting up with the army, with one tiny section of it operating along the road on which we were. Multiply this by a thousand and you have the whole. Ahead was the army's larder on wheels; a procession of big motor transport trucks keeping their intervals of distance with the precision of a battleship fleet at sea. We should have known that they belonged to the army by the deafness of the drivers to appeals to let us pass. All army transports are like that. What the deuced right has anybody to pass? They are the transport, and only fighting men belong in front of them. Our car in trying to go by to one side got stuck in a rut that an American car, built for bad roads, would have made nothing of; which proves again how closely European armies are tied to their fine highways. We got out, and here again was our statesman putting his shoulder to the wheel. That is the way of the French in war. Everybody tries to help. By this time the transport chauffeurs remembered that they also were Frenchmen; and as Frenchmen are polite even in time of war, they let us by. A motor-cyclist approached with his hand up. "Stop here!" he called.
