Saturday, 23.—I have just seen a most magnificent sight; one which I have often dreamed of, often longed to behold, and having beheld, never shall forget. Mount Vesuvius is at this moment blazing like a huge furnace; throwing up every minute, or half minute, columns of fire and red-hot stones, which fall in showers and bound down the side of the mountain. On the east, there are two distinct streams of lava descending, which glow with almost a white heat, and every burst of flame is accompanied by a sound resembling cannon at a distance.—

I can hardly write, my mind is so overflowing with astonishment, admiration, and sublime pleasure: what a scene as I looked out on the bay from the Sante Lucia! On one side, the evening star and the thread-like crescent of the new moon were setting together over Pausilippo, reflected in lines of silver radiance on the blue sea; on the other the broad train of fierce red light glared upon the water with a fitful splendour, as the explosions were more or less violent: before me all was so soft, so lovely, so tranquil! while I had only to turn my head to be awe-struck by the convulsion of fighting elements.

I remember, that on our first arrival at Naples, I was disappointed because Vesuvius did not smoke so much as I had been led to expect from pictures and descriptions. The smoke then lay like a scarcely perceptible cloud on the highest point, or rose in a slender white column; to-day and yesterday, it has rolled from the crater in black volumes, mixing with the clouds above, and darkening the sky.

Half-past twelve.—I have walked out again: the blaze from the crater is less vivid; but there are now four streams of lava issuing from it, which have united in two broad currents, one of which extends below the hermitage. It is probable that by to-morrow night it will have reached the lower part of the mountain.

Sunday, 24.—Just returned from chapel at the English ambassador's, where the service was read by a dandy clergyman to a crowd of fine and superfine ladies and gentlemen, crushed together into a hot room. I never saw extravagance in dress carried to such a pitch as it is by my countrywomen here,—whether they dress at the men or against each other, it is equally bad taste. The sermon to-day was very appropriate, from the text, "Take ye no thought what ye shall eat, or what ye shall drink, or what ye shall put on," and, I dare say, it was listened to with singular edification.

5 o'clock.—We have been driving along the Strada Nuova in L**'s britschka, whence we had a fine view of Vesuvius. There are tremendous bursts of smoke from the crater. At one time the whole mountain, down to the very base, was almost enveloped, and the atmosphere round it loaded with the vapour, which seemed to issue in volumes half as large as the mountain itself. If horses are to be had we go up to-night.

Monday night.—I am not in a humour to describe, or give way to any poetical flights, but I must endeavour to give a faithful, sober, and circumstantial account of our last night's expedition, while the impression is yet fresh on my mind; though there is, I think, little danger of my forgetting. We procured horses, which, from the number of persons proceeding on the same errand with ourselves, was a matter of some difficulty. We set out at seven in the evening in an open carriage, and almost the whole way we had the mountain before us, spouting fire to a prodigious height. The road was crowded with groups of people who had come out from the city and environs to take a nearer view of the magnificent spectacle, and numbers were hurrying to and fro in those little flying corricoli which are peculiar to Naples. As we approached, the explosions became more and more vivid, and at every tremendous burst of fire our friend L** jumped half off his seat, making most loud and characteristic exclamations,—"By Jove! a magnificent fellow! now for it, whizz! there he goes, sky high, by George!" The rest of the party were equally enthusiastic in a different style; and I sat silent and quiet from absolute inability to express what I felt. I was almost breathless with wonder, and excitement, and impatience to be nearer the scene of action. While my eyes were fixed on the mountain, my attention was, from time to time, excited by regular rows of small shining lights, six or eight in number, creeping, as it seemed, along the edge of the stream of lava; and, when contrasted with the red blaze which rose behind, and the gigantic black back-ground, looking like a procession of glowworms. These were the torches of travellers ascending the mountain, and I longed to be one of them.

We reached Resina a little before nine, and alighted from the carriage; the ascent being so rugged and dangerous, that only asses and mules accustomed to the road are used. Two only were in waiting at the moment we arrived, which L** immediately secured for me and himself; and though reluctant to proceed without the rest of the party, we were compelled to go on before, that we might not lose time, or hazard the loss of our monture. We set off then, each with two attendants, a man to lead our animals and a torch-bearer. The road, as we ascended, became more and more steep at every step, being over a stream of lava, intermixed with stones and ashes, and the darkness added to the difficulty. But how shall I describe the scene and the people who surrounded us; the landscape partially lighted by a fearful red glare, the precipitous and winding road bordered by wild looking gigantic aloes, projecting their huge spear-like leaves almost across our path, and our lazzaroni attendants with their shrill shouts, and strange dresses, and wild jargon, and striking features, and dark eyes flashing in the gleam of the torches, which they flung round their heads to prevent their being extinguished, formed a scene so new, so extraordinary, so like romance, that my attention was frequently drawn from the mountain, though blazing in all its tumultuous magnificence.

The explosions succeeded each other with terrific rapidity about two in every three minutes; and the noise I can only compare to the roaring and hissing of ten thousand imprisoned winds, mingled at times with a rumbling sound like artillery, or distant thunder. It frequently happened that the guides, in dashing their torches against the ground, set fire to the dried thorns and withered grass, and the blaze ran along the earth like wildfire, to the great alarm of poor L**, who saw in every burning bush a stream of lava rushing to overwhelm us.

Before eleven o'clock we reached the Hermitage, situated between Vesuvius and the Somma, and the highest habitation on the mountain. A great number of men were assembled within, and guides, lazzaroni, servants, and soldiers, were lounging round. I alighted, for I was benumbed and tired, but did not like to venture among those people, and it was proposed that we should wait for the rest of our party a little further on. We accordingly left our donkeys and walked forward upon a kind of high ridge which serves to fortify the Hermitage and its environs against the lava. From this path, as we slowly ascended, we had a glorious view of the eruption; and the whole scene around us, in its romantic interest and terrible magnificence, mocked all power of description. There were, at this time, five distinct torrents of lava rolling down like streams of molten lead; one of which extended above two miles below us and was flowing towards Portici. The showers of red-hot stones flew up like thousands of sky rockets: many of them being shot up perpendicularly fell back into the crater, others falling on the outside bounded down the side of the mountain with a velocity which would have distanced a horse at full speed: these stones were of every size, from two to ten or twelve feet in diameter.
