Σελίδα 138 - ... of pines, these again forming themselves into festoons of white feathery smoke, in the most fanciful manner imaginable, intermixed with the finest particles of falling ashes, which at one time assumed the appearance of innumerable plumes of black and white ostrich feathers surmounting each other; at another, that of the light *avy branches of a weeping willow.
Σελίδα 232 - This continued with tremendous force until the 5th of June, exhibiting the awful, yet magnificent spectacle of a perfect river of fire, distinctly seen from Fayal, running into the sea. On that day, the 5th, we experienced that its force began to fail ; and in a few days after it ceased entirely. The distance of the crater from the sea is about four miles, and its elevation about three thousand five hundred feet.
Σελίδα 128 - ... of irregular elevations surrounded by redness and vascularity. When divided longitudinally, Fig. II., it appeared to be formed entirely of cerebriform matter and fine bloodvessels ; hardly any trace of its natural structure being observable. It presented a lobulated structure; the lobules varying from the size of a small pea to that of a large gooseberry ; these being again divided and subdivided into smaller ones — the boundaries of the lobules and the intersections of the latter were the...
Σελίδα 138 - ... from a perpendicular line, the angle of inclination being universally to windward ; this was rapidly succeeded by a second, third, and fourth, each acquiring greater velocity, and overtopping the other, till they had attained an altitude as much above the level of our eye, as the sea was below it. As the impetus with which the columns were severally propelled diminished, and their ascending motion had nearly ceased, they broke into various branches resembling a...
Σελίδα 144 - ... fathoms. From walking round it, in about twelve minutes, I should judge that it was something less than a mile in circumference; but the most extraordinary part was the crater, the mouth of which, on the side facing St. Michael's, was nearly level with the sea. It was filled with water, at that time boiling, and was emptying itself into the sea, by a small stream about six yards over, and by which I should suppose it was continually filled again at high.water.
Σελίδα 141 - That part of the sea where the volcano was situated was upwards of thirty fathoms deep, and at the time of our viewing it the volcano was only four days old. Soon after our arrival on the cliff, a peasant observed he could discern a peak above the water ; we looked, but could not see it : however, in less than half an hour it was plainly visible, and before we quitted the...

About sixty persons were thus miserably scalded, some of whom died on the spot, or in a few days after. Numbers of cattle shared the same fate. The judge and principal inhabitants left the island very early.
Σελίδα 144 - I found the complete skeleton of a guardfish, the bones of which being perfectly burnt, fell to pieces upon attempting to take them up ; and by the account of the inhabitants on the coast of St. Michael's, great numbers of fish had been destroyed during the early part of the eruption, as large quantities, probably suffocated or poisoned, were occasionally found drifted into the small inlets or bays. The island, like other volcanic productions, is composed principally of porous substances, and generally...
Σελίδα 142 - ... reaching the island found the surf on the beach very high, Rowing round to the lee side, with some little difficulty, by the aid of an oar, as a pole, I jumped on shore, and was followed by the other officers. We found a narrow beach of black ashes, from which the side of the island rose in general too steep to admit of our ascending; and, where we could have clambered up...
