Under the vast, rugged buttresses of rock--serrated with gaps between them, like the surviving parapets of a gigantic fortress, the mass of which had sunk beneath the sea--the vessel seemed shrunk to a mere speck; and close under these mural precipices, rising to the height of two thousand feet, she had, in worse than darkness, crept along within hearing of the surf. On either bow, when anchored, were the two stupendous, square-faced bluffs, between which, liked a ruined embrasure, yawned the ravine containing Jamestown. High and distant against the sky, was frowning a battery of heavy guns, looking down upon the decks; and beyond the valley, the road zigzagged along the nine hundred feet of steep-faced, ladder hill. Green thickets were creeping up the valleys; and plains of verdant turf here and there overlapped the precipices. Subsequently, on an inland excursion, were seen the fantastic forms of Lot and his wife, more than fourteen hundred feet in height; and black pillars, or shafts of basaltic columns, standing high amid the snowy foam of the surf. Patches of luxuriant vegetation were suddenly broken by astounding chasms, such as the “Devil’s Punch Bowl.” This striking and majestic scenery, on an island ten miles in length and six in breadth, arises from its great height and its volcanic configuration. The occurrence of small oceanic deposits high up on its plains, indicates fits of elevation ere it reached its present altitude. The _Yam-flowers_ (the _sobriquet_ of the island ladies) need not, however, fear that the joke of travellers will prove a reality, by the island again being drawn under water like a turtle’s head. Visits were received from the chief-justice, the commandant and officers of the garrison. Invitations were sent to dine “with the mess.” The American consul, and many of the inhabitants, joined in extending unbounded hospitality to the officers, which was duly appreciated by African cruisers. A collation to their hospitable friends, on the quarterdeck of the Perry, was also partaken of by the officers of a British cruiser, which, on leaving the island, ran across the stern of the vessel, gave three cheers, and dipped her colors. The proprietor of Longwood, once the prison of Napoleon, received the officers and their friends at a pic-nic, when a visit was made to that secluded spot, so suggestive of interesting associations. Every means was used to leave a sense of grateful remembrance on the minds of the visitors to the island. One watch of the crew were constantly on shore, in search of health and enjoyment.
