I hurried off to the Post Office, to await the arrival of the diligence from Palermo. The office is in the Strada Etnea, the main street of Catania, which runs straight through the city, from the sea to the base of the mountain, whose peak closes the long vista. The diligence was an hour later than usual, and I passed the time in watching the smoke which continued to increase in volume, and was mingled, from time to time, with jets of inky blackness. The postilion said he had seen fires and heard loud noises during the night. According to his account, the disturbances commenced about midnight. I could not but envy my friend Cæsar, who was probably at that moment on the summit, looking down into the seething fires of the crater. At last, we rolled out of Catania. There were in the diligence, besides myself, two men and a woman, Sicilians of the secondary class. The road followed the shore, over rugged tracts of lava, the different epochs of which could be distinctly traced in the character of the vegetation. The last great flow (of 1679) stood piled in long ridges of terrible sterility, barely allowing the aloe and cactus to take root in the hollows between. The older deposits were sufficiently decomposed to nourish the olive and vine; but even here, the orchards were studded with pyramids of the harder fragments, which are laboriously collected by the husbandmen. In the few favored spots which have been untouched for so many ages that a tolerable depth of soil has accumulated, the vegetation has all the richness and brilliancy of tropical lands. The palm, orange, and pomegranate thrive luxuriantly, and the vines almost break under their heavy clusters. The villages are frequent and well built, and the hills are studded, far and near, with the villas of rich proprietors, mostly buildings of one story, with verandahs extending their whole length. Looking up towards Etna, whose base the road encircles, the views are gloriously rich and beautiful. On the other hand is the blue Mediterranean and the irregular outline of the shore, here and there sending forth promontories of lava, cooled by the waves into the most fantastic forms.
