They spent the night in a comfortable house and the next day continued their journey into the Jura, which he explains is a word from a local term, joux, meaning a crag or mountain. The next day they proceeded on their way. It was the twenty-fourth of October, 1779.
“It was a clear, cool morning; there was hoar frost on the meadows; here and there light mist-wreaths were drifting over; we could see fairly well over the lower part of the valley; our house lay at the foot of the Western Noir Mont. About eight o’clock we set forth on horseback, and in order to enjoy the sun at once we rode toward the west. The part of the valley where we were proceeding consists of fenced meadows which toward the lake become rather swampy. The Orbe flows through the center of it. The inhabitants have established themselves in single houses partly on its banks, partly in clustering villages which bear simple names suggested by their situation. The first one which we passed through was Le Sentier. From afar we saw La Dent de Baulion smiling across a fog bank which hung over the lake. The valley widened; we came behind a crag which hid the lake from us and entered another village called Le Lieu; the fog was rising and then settling down again before the sun.
“Near here is a little lake which seems to have neither inflow nor outflow. The weather became perfectly clear and as we reached the foot of the Dent de Baulion we found here the northerly end of a large lake which, as it turns toward the west, has its outlet into the little one through a dam over which is built a bridge. The village above it is called Le Pont. The lay of the little lake is, as it were, in its own little valley, which one might call a very neat arrangement. At the western end is a noteworthy mill constructed in a cleft of the rock which once the little lake filled. Now it is dammed away and the mill is built over the chasm. The water runs through sluices to the millwheels and from there dashes down into the clefts of the rocks, where it is swallowed up, and a mile away joins the Valorbe, where it once more takes the name of the upper stream.
“These sluices (entonniers) have to be kept clear, else the water would rise and fill up the cleft again and drown the mill, as has happened more than once. Men were busy at work, some removing the decomposed limestone, some strengthening the structure.
“We rode back over the bridge to Le Pont and took a guide to La Dent. As we mounted we had a fine view of the large lake below us in its whole extent. To the eastward Le Noir Mont forms its boundary; behind that the bald head of the Dôle comes into sight; to the westward the precipitous crags, quite naked toward the lake, confine it.
“The sun grew hot; it was between eleven and noon. Gradually we began to get a prospect over the whole valley and could recognize in the distance Le Lac des Rousses, and coming up to our feet the region through which we had been riding and the road which still remained for us to accomplish. As we mounted higher we talked about the vast extent of land and of the rulers which could be distinguished from that height and with such thoughts we attained the summit; but another drama was there prepared for us. Only the lofty mountain chains were visible under a clear and cheerful sky; all the regions below were bedecked with a white woolly sea of fog which stretched from Geneva northward to the very horizon and gleamed in the sun. Out of this to the east arose the whole unbroken range of snow and ice-covered mountains, without respect to the names of the nations and princes who lay claim to the possession of them, subjected only to one great Overlord and to the glance of the sun, which painted them a lovely rosy hue.
“Mont Blanc over opposite to us was evidently the highest; the ice-mountains of Valais and of the Oberland came next and finally closed in the lower mountain of the Canton of Bern. Toward the west in one place the sea of fog was unbounded; to the left in the farthest distance the mountains of Solothurn showed themselves; nearer still those of Neuchâtel; directly before us a few of the lower peaks of the Jura; below us lay some of the houses of Baulion whereto La Dent belongs and whence it gets the name. Toward the west the whole horizon is shut off by the Franche-Comté with a stretch of low wooded mountains, one of which stood out quite alone by itself toward the northwest. In front was a lovely view.
“Here is the sharp point which gives this peak the name of a tooth. It slopes down steeply and, if anything, bends inward a little; in the depths a little fir-wood valley with fine grassy meadows is shut in; directly beyond lies the valley called Valorbe, where one can see the Orbe springing from the rocks and follow in imagination its downward course under the ground to the little lake.
