The morning outside came living and sharp after the gale--almost chilly. Under a scattered but clearing sky I first limped, then, as my blood warmed, strode down the path that led between the trees of the farther vale and was soon following a stream that leaped from one fall to another till it should lead me to the main road, to Belfort, to the Jura, to the Swiss whom I had never known, and at last to Italy. But before I call up the recollection of that hidden valley, I must describe with a map the curious features of the road that lay before me into Switzerland. I was standing on the summit of that knot of hills which rise up from every side to form the Ballon d'Alsace, and make an abrupt ending to the Vosges. Before me, southward and eastward, was a great plain with the fortress of Belfort in the midst of it. This plain is called by soldiers 'the Gap of Belfort', and is the only break in the hill frontier that covers France all the way from the Mediterranean to Flanders. On the farther side of this plain ran the Jura mountains, which are like a northern wall to Switzerland, and just before you reach them is the Frontier. The Jura are fold on fold of high limestone ridges, thousands of feet high, all parallel, with deep valleys, thousands of feet deep, between them; and beyond their last abrupt escarpment is the wide plain of the river Aar. Now the straight line to Rome ran from where I stood, right across that plain of Belfort, right across the ridges of the Jura, and cut the plain of the Aar a few miles to the west of a town called Solothurn or Soleure, which stands upon that river. It was impossible to follow that line exactly, but one could average it closely enough by following the high road down the mountain through Belfort to a Swiss town called Porrentruy or Portrut--so far one was a little to the west of the direct line. From Portrut, by picking one's way through forests, up steep banks, over open downs, along mule paths, and so forth, one could cross the first ridge called the 'Terrible Hill', and so reach the profound gorge of the river Doubs, and a town called St Ursanne. From St Ursanne, by following a mountain road and then climbing some rocks and tracking through a wood, one could get straight over the second ridge to Glovelier. From Glovelier a highroad took one through a gap to Undervelier and on to a town called Moutier or Munster. Then from Munster, the road, still following more or less the line to Rome but now somewhat to the east of it, went on southward till an abrupt turn in it forced one to leave it. Then there was another rough climb by a difficult path up over the last ridge, called the Weissenstein, and from its high edge and summit it was but a straight fall of a mile or two on to Soleure.
