I know a valley in North Wales, between the mountains and the sea. It is a beautiful valley, snug, comfortable, sheltered by the mountains from all the bitter blasts. But it is very enervating, and I remember how the boys were in the habit of climbing the hill above the village to have a glimpse of the great mountains in the distance, and to be stimulated and freshened by the breezes which came from the hilltops, and by the great spectacle of their grandeur. We have been living in a sheltered valley for generations. We have been too comfortable and too indulgent—many, perhaps, too selfish—and the stern hand of fate has scourged us to an elevation where we can see the great everlasting things that matter for a nation—the great peaks we had forgotten, of Honour, Duty, Patriotism, and, clad in glittering white, the great pinnacle of sacrifice pointing like a rugged finger to Heaven. We shall descend into the valleys again; but as long as the men and women of this generation last, they will carry in their hearts the image of those great mountain peaks.
