Folkestone had made me think of the mouth of a great funnel, into which all broad Britain had been pouring men and guns and all the manifold supplies and stores of modern war. And the trip across the narrow, well guarded lane in the Channel had been like the pouring of water through the neck of that same funnel. Here in Boulogne was the opening. Here the stream of men and sup-plies spread out to begin its orderly, irresistible flow to the front. All of northern France and Belgium lay before that stream; it had to cover all the great length of the British front. Not from Boulogne alone, of course; I knew of Dunkirk and Calais, and guessed at other ports. There were other funnels, and into all of them, day after day, Britain was pouring her tribute; through all of them she was offering her sacrifice, to be laid upon the altar of strife. Here, much more than at Folkestone, as it chanced, I saw at once another thing. There was a double funnel. The stream ran both ways. For, as we steamed into Boulogne, a ship was coming out--a ship with a grim and tragic burden. She was one of our hospital ships. But she was guarded as carefully by destroyers and aircraft as our transport had been. The Red Cross meant nothing to the Hun--except, perhaps, a shining target. Ship after ship that bore that symbol of mercy and of pain had been sunk. No longer did our navy dare to trust the Red Cross. It took every precaution it could take to protect the poor fellows who were going home to Blighty. As we made our way slowly in, through the crowded harbor, full of transports, of ammunition ships, of food carriers, of destroyers and small naval craft of all sorts, I began to be able to see more and more of what was afoot ashore. It was near noon; the day that had been chosen for my arrival in France was one of brilliant sunshine and a cloudless sky. And my eyes were drawn to other hospital ships that were waiting at the docks. Motor ambulances came dashing up, one after the other, in what seemed to me to be an endless stream. The pity of that sight! It was as if I could peer through the intervening space and see the bandaged heads, the places where limbs had been, the steadfast gaze of the boys who were being carried up in stretchers. They had done their task, a great number of them; they had given all that God would let them give to King and country. Life was left to them, to be sure; most of these boys were sure to live. But to what maimed and incomplete lives were they doomed! The thousands who would be cripples always--blind, some of them, and helpless, dependent upon what others might choose or be able to do for them. It was then, in that moment, that an idea was born, vaguely, in my mind, of which I shall have much more to say later.
