I climbed, then, over slippery pine needles and under the charged air of those trees, which was full of dim, slanting light from the afternoon sun, till, nearly at the summit, I came upon a clearing which I at once recognized as a military road, leading to what we used to call a 'false battery', that is, a dug-out with embrasures into which guns could be placed but in which no guns were. For ever since the French managed to produce a really mobile heavy gun they have constructed any amount of such auxiliary works between the permanent forts. These need no fixed guns to be emplaced, since the French can use now one such parapet, now another, as occasion serves, and the advantage is that your guns are never useless, but can always be brought round where they are needed, and that thus six guns will do more work than twenty used to do. This false battery was on the brow of the hill, and when I reached it I looked down the slope, over the brushwood that hid the wire entanglements, and there was the whole valley of the Moselle at my feet. As this was the first really great height, so this was the first really great view that I met with on my pilgrimage. I drew it carefully, piece by piece, sitting there a long time in the declining sun and noting all I saw. Archettes, just below; the flat valley with the river winding from side to side; the straight rows of poplar trees; the dark pines on the hills, and the rounded mountains rising farther and higher into the distance until the last I saw, far off to the south-east, must have been the Ballon d'Alsace at the sources of the Moselle--the hill that marked the first full stage in my journey and that overlooked Switzerland. Indeed, this is the peculiar virtue of walking to a far place, and especially of walking there in a straight line, that one gets these visions of the world from hill-tops. When I call up for myself this great march I see it all mapped out in landscapes, each of which I caught from some mountain, and each of which joins on to that before and to that after it, till I can piece together the whole road. The view here from the Hill of Archettes, the view from the Ballon d'Alsace, from Glovelier Hill, from the Weissenstein, from the Brienzer Grat, from the Grimsel, from above Bellinzona, from the Principessa, from Tizzano, from the ridge of the Apennines, from the Wall of Siena, from San Quirico, from Radicofani, from San Lorenzo, from Montefiascone, from above Viterbo, from Roncigleone, and at last from that lift in the Via Cassia, whence one suddenly perceives the City. They unroll themselves all in their order till I can see Europe, and Rome shining at the end.
