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 toward 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 toward 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 toward 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 broken loose, had fled to the drained lands. Enjoying its liberty, it was galloping up and down 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.
