_Punch, brothers, punch with care, Punch in the presence of the passenjaire, A pink trip slip for a five-cent fare_-- and so on. Northeast then, in an open grey car with "Belgian Red Cross" on each side of the machine. Northeast in a bitter wind, into a desolate and almost empty country of flat fields, canals and roads bordered by endless rows of trees bent forward like marching men. Northeast through Gravelines, once celebrated of the Armada and now a manufacturing city. It is curious to think that a part of the Armada went ashore at Gravelines, and that, by the shifting of the English Channel, it is now two miles inland and connected with the sea by a ship canal. Northeast still, to Dunkirk. From Calais to Gravelines there had been few signs of war--an occasional grey lorry laden with supplies for the front; great ambulances, also grey, and with a red cross on the top as a warning to aëroplanes; now and then an armoured car. At Gravelines the country took on a more forbidding appearance. Trenches flanked the roads, which were partly closed here and there by overlapping earthworks, so that the car must turn sharply to the left and then to the right to get through. At night the passage is closed by barbed wire. In one place a bridge was closed by a steel rope, which a sentry lowered after another operation on the pink slip. The landscape grew more desolate as the daylight began to fade, more desolate and more warlike. There were platforms for lookouts here and there in the trees, prepared during the early days of the war before the German advance was checked. And there were barbed-wire entanglements in the fields. I had always thought of a barbed-wire entanglement as probably breast high. It was surprising to see them only from eighteen inches to two feet in height. It was odd, too, to think that most of the barbed wire had been made in America. Barbed wire is playing a tremendous part in this war. The English say that the Boers originated this use for it in the South African War. Certainly much tragedy and an occasional bit of grim humour attach to its present use. With the fortified town of Dunkirk--or Dunkerque--came the real congestion of war. The large square of the town was filled with soldiers and marines. Here again were British uniforms, British transports and ambulances. As a seaport for the Allied Armies in the north, it was bustling with activity. The French and Belgians predominated, with a sprinkling of Spahis on horseback and Turcos. An air of activity, of rapid coming and going, filled the town. Despatch riders on motor cycles, in black leather uniforms with black leather hoods, flung through the square at reckless speed. Battered automobiles, their glass shattered by shells, mud guards crumpled, coated with clay and riddled with holes, were everywhere, coming and going at the furious pace I have since learned to associate with war.
