A long but easy ascent led to the top of the pass, the ridge we mounted being thickly clothed with evergreen shrubbery, the arbutus predominating, profusely decked with fruit and flower. The summit of the pass opened to us a double view in strong contrast. Looking back, we once more saw through a gap the mountains of Corsica, in faint outlines, eighty miles distant, with a glimpse of a blue stripe of water, the Straits of Bonifacio. Turning southward, we stood at the summit of a long winding glen richly wooded with ilex and cork trees, and far away beneath there lay before us a broad plain partially covered with a sea of vapour, not like the gay wreaths of mist that lightly floated over the elevated plateau surrounding Tempio, but so still, so condensed, so white, as to have been easily mistaken for a frozen lake powdered with snow, and its hills for islands rising out of the water.[53]
But such an image is unsuited to the climate of Sardinia at any season. Smiling as the landscape now appeared, its most striking feature was associated with the idea of death.
That dense creamy vapour, formed by the pestiferous exhalations of the lowlands, is the death shroud of the plain outstretched beneath it.

During the heats of summer, nay, sometimes from April till the latter end of November, the ravages of the deadly _intempérie_ extend throughout the island to such a degree that in Captain Smyth's list of nearly 350 towns and villages included in his “Statistical Table of Sardinia,” full a third are noted as insalubrious. The disorder has the same character as malaria, but is far more virulent. Captain Smyth thus describes the symptoms: “The patient is first attacked by a headache and painful tension of the epigastric region, with alternate sensations of heat and chilliness; a fever ensues, the exacerbations of which are extremely severe, and are followed by a mournful debility, more or less injurious even to those accustomed to it, but usually fatal to strangers.” We have conversed with natives and residents who have recovered from repeated attacks of _intempérie_; foreigners suffer most. “Instances have been related to me,” observes Captain Smyth, “of strangers landing for a few hours only from Italian coasters, who were almost immediately carried off by its virulence; indeed, the very breathing of the air by a foreigner at night, or in the cool of the evening, is considered as certain death in some parts.”[54]
