I am writing this in a very miserable auberge, and feel neither strength nor humour to make it any longer: therefore I must bid you a very good night.
Fondi, Feb. 23, 1787.
We were on the road very early,—by three in the morning. As the day broke we found ourselves on the Pontine Marshes, which have not by any means so ill an appearance as the common description in Rome would make out. Of course, by merely once passing over the marshes, it is not possible to judge of so great an undertaking as that of the intended draining of them, which necessarily requires time to test its merits; still it does appear to me, that the works which have commenced by the Pope's orders, will, to a great extent at least, attain the desired end. Conceive to yourself a wide valley, which, as it stretches from north to south, has but a very slight fall, but which towards the east and the mountains is extremely low, but rises again considerably towards the sea on the west. Punning in a straight line through the whole length of it, the ancient Via Appia has been restored. On the right of the latter the principal drain has been cut, and in it the water flows with a rapid fall. By means of it the tract of land to the right has been drained, and is now profitably cultivated. As far as the eye can see, it is either already brought into cultivation or evidently might be so, if farmers could be found to take it, with the exception of one spot, which lies extremely low.
The left side, which stretches towards the mountains, is more difficult to be managed. Here, however, cross-drains pass under the raised way into the chief drain; as, however, the surface sinks again towards the mountains, it is impossible by this means to carry off the water entirely. To meet this difficulty it is proposed, I was told, to cut another leading drain along the foot of the mountains. Large patches, especially towards Terracina, are thinly planted with willows and poplars.
The posting stations consist merely of long thatched sheds. Tischbein sketched one of them, and enjoyed for his reward a gratification which only he could enjoy. A white horse having broke loose had fled to the drained lands. Enjoying its liberty, it was galloping backwards and forwards on the brown turf like a flash of lightning; in truth it was a glorious sight, rendered significant by Tischbein's rapture.
At the point where the ancient village of Meza once stood, the Pope has caused to be built a large and fine building, which indicates the centre of the level. The sight of it increases one's hopes and confidence of the success of the whole undertaking. While thus we travelled on, we kept up a lively conversation together, not forgetting the warning, that on this journey one must not go to sleep; and, in fact, we were strongly enough reminded of the danger of the atmosphere, by the blue vapour which, even in this season of the year, hangs above the ground. On this account the more delightful, as it was the more longed for, was the rocky site of Terracina; and scarcely had we congratulated ourselves at the sight of it, than we caught a view of the sea beyond. Immediately afterwards the other side of the mountain city presented to our eye a vegetation quite new to us. The Indian figs were pushing their large fleshy leaves amidst the gray green of dwarf myrtles, the yellowish green of the pomegranate, and the pale green of the olive. As we passed along, we noticed both flowers and shrubs quite new to, us. On the meadows the narcissus and the adonis were in flower. For a long time the sea was on our right, while close to us on the left ran an unbroken range of limestone rocks. It is a continuation of the Apennines, which runs down from Tivoli and touches the sea, which it does not leave again till you reach the Campagna di Romana, where it is succeeded by the volcanic formations of Frescati, Alba, and Velletri, and lastly by the Pontine Marshes. Monte Circello, with the opposite promontory of Terracina, where the Pontine Marshes terminate, in all probability consists also of a system of chalk rocks.
We left the sea coast, and soon reached the charming plain of Fondi. Every one must admire this little spot of fertile and well cultivated land, enclosed with hills, which themselves are by no means wild. Oranges, in great numbers, are still hanging on the trees; the crops, all of wheat, are beautifully green; olives are growing in the fields, and the little city is in the bottom. A palm tree, which stood out a marked object in the scenery, received our greetings. So much for this evening. Pardon the scrawl. I must write without thinking, for writing sake. The objects are too numerous, my resting place too wretched, and yet my desire to commit something to paper too great. With nightfall we reached this place, and it is now time to go to rest.
