spect, might be regarded as a sort of jasper or hornblende; in another, looked like clay-slate. I found some pebbles rounded, others of a rhomboidal shape, others of irregular forms and of various colours: moreover, many varieties of the primeval limestone; not a few specimens of breccia, of which the substratum was lime, and holding jasper or modifications of limestone; rubbles of muschelkalk were not wanting either.
The horses here are fed on barley, cut straw (häckerling), and clover. In spring they give them the green barley, in order to refresh them,—per rinfrescar is the phrase. As there are no meadows here, they have no hay. On the hillsides there are some pasture-lands; and also in the corn-fields, as a third is always left fallow. They keep but few sheep, and these are of a breed from Barbary. On the whole, they have more mules than horses, because the hot food suits the former better than the latter.
The plain on which Palermo is situated, as well as the districts of Ai Colli, which lie without the city, and a part also of Baggaria, have for their basis the muschelkalk, of which the city is built. There are, for this purpose, extensive quarries of it in the neighbourhood. In one place, near Monte Pellegrino, they are more than fifty feet deep. The lower layers are of a whiter hue. In it are found many petrified corals and other shell-fish, but principally great scallops. The upper stratum is mixed with red marl, and contains but few, if any, fossils. Eight above it lies the red marl, of which, however, the layer is not very stiff.
Monte Pellegrino, however, rises out of all this. It is a primary limestone, has many hollows and fissures, which, although very irregular, when closely observed are found to follow the order of the strata. The stone is close, and rings when struck.
