The Grand Curral is the central vent of a volcano originally submarine, and, like the Peak of Tenerife, of the age miocene. Fossils of that epoch have been found upon the crater-walls of both. Subsequent movements capped it with subaerial lavas and conglomerates; and wind and weather, causing constant degradation, deepened the bowl and almost obliterated signs of igneous action. This is general throughout Madeira; the only craters still noticed by guide-books are the Lagos (Lake) de Santo Antonio da Serra, east of Funchal and west of Machico, 500 feet across by 150 deep; and, secondly, the Fanal to the north-west, about 5,000 feet above sea-level. The Curral floor, smooth and bald, is cut by a silvery line of unsunned rivulet which at times must swell to a torrent; and little white cots like egg-shells are scattered around the normal parish-church, Nossa Senhora do Livramento. The basin-walls, some 2,000 feet high and pinnacled by the loftiest peaks in the island, are profusely dyked and thickly and darkly forested; and in the bright blue air, flecked with woolpack, Manta, the buzzard, and frequent kestrels pass to and fro like flies. Beyond the Soccorridos lies the charming valley of Camara dos Lobos, popularly Cama di Lobos, [Footnote: It is placed west instead of east of Cape Girao in the _Conoise Handbook of Madeira_, by the Rev. J. M. Rendell. London: Kegan Paul and Co., 1881.] the lair of the sea-wolves, or seals. With its vivid lines of sugar-cane, its terraces, its fine remains of forest vegetation, and its distances of golden lights, of glazed blue half-lights, and of purple shades, it looks like a stage-rake, a _décor de théatre_. Tunny-fishing, wine-making, and sugar-boiling have made it, from a 'miserable place,' a wealthy townlet whose tall white houses would not disgrace a city; two manufactories show their craft by heaps of _bagasse_, or trash; and the deep shingly bay, defended by a _gurgulho_ of basaltic pillars, is covered with piscator's gear and with gaily painted green boats. 'Seal's Lair' was the model district of wine-production, like its neighbour on the north-western upland, Campanario, famous for its huge Spanish chestnut: both were, however, wasted by the oidium of 1852. In 1863 it partially recovered, under the free use of sulphur; but now it has been ravaged by the more dangerous phylloxera, which is spreading far faster than Mr. Henry Vizetelly supposes. [Footnote: _Facts about Port and Madeira_, by Henry Vizetelly, who visited the island in 1877. The papers first appeared in the (old original) Pall Mall Gazette (August 26-September 4,1877), and then were published in a volume by Ward and Lock, 1880] The only cure of this pest known to Madeira is the troublesome and expensive process practised by a veteran oenologist, Mr. Leacock.
