to the distant horizon) should seem so low.  The reason that this white wall of cliffs seems so low is that the traveller is standing upon the last of a series of great steps which have led him up towards the frontier, much as the prairie leads one up towards the Rockies in Colorado.  When he has passed through the very pleasant wood which lies directly beneath the cliffs, and reaches the little village of Roncesvalles itself, he wonders still more that so famous a pass should be so small a thing.  The pass from this side is so broad, with so low a saddle of grass, that it seems more like the crossing of the Sussex Downs than the crossing of an awful range of mountains.  It is a rounded gap, up to which there lifts a pretty little wooded combe; and no one could be certain, during the half-hour spent in climbing such a petty summit, that he was, in so climbing, conquering Los Altos, the high Pyrenees.

But when the summit is reached, then the meaning of the “Imus Pyrenaeus,” and the place that passage has taken in history, is comprehended in a moment.  One sees at what a height one was in that plain of Roncesvalles, and one sees how the main range dominates the world; for down below one an enormous cleft into the stuff of the mountains falls suddenly and almost sheer, and you see unexpectedly beneath you the approach from France into Spain.  The gulf at its narrowest is tremendous; but, more than that, when the floor of the valley is reached, that floor itself slopes away down and down by runs and by cascades towards the very distant plains of the north, upon which the funnel debouches.  Moreover, it was up this gulf, and from the north, that the armies came; it was this vision of a precipice that seized them when their leaders had determined to invade the Peninsula.  This also was what, for so many generations, so many wanderers must have seen who came to wonder at the place where the rearguard of Charlemagne had been destroyed.

The whole of the slope is covered with an ancient wood, and this wood is so steep that it would be impossible or dangerous to venture down it.  The old Carolingian road skirts the mountain-side with difficulty, clinging well up upon its flank; the great modern road, which is excellent and made for artillery, has to go even nearer the summit; below them there falls away a slant or edge to which the huge beech trees cling almost parallel to the steep earth, running their perpendicular lines so high and close against the hill that they look like pines.  As you peer down in among the trunks, you see the darkness increasing until the eye can penetrate no more, and dead, enormous trees that have lived their centuries, and have fallen perhaps for decades, lie across the aisles of the wood, propped up against their living fellows; for, by one of those political accidents which are common throughout the whole length of the Pyrenees, both sides of the watershed belong to Spain, so that no Government or modern energy has come to disturb the silence.  One would swear that the last to order this wood were the Romans.
