All dogs can swim, but only water-dogs have the foot webbed and the hair shaggy. The Englishman is the only one you can thoroughly salt, and make all his bread biscuit, so that he can both be a boy at fifty, and yet chew all the hardships of experience without getting conscious of his wisdom. So I reflected, at any rate, half joke, half earnest, while hastening to the Liverpool steamer, which lay broadside to the quay, and, betwixt letting off steam and getting it up, was blowing like a mighty whale come up to breathe. The passengers were streaming up the plank, across by her paddle-boxes, as it were so many Jonahs going into its belly; amongst whom I was glad to see my nautical friends taking a shorter cut to the steerage, and establishing themselves with a sort of half-at-home expression in their sunburnt weatherly faces. In a little while the "City of Glasgow" was swimming out of the firth, with short quick blows of her huge fins, that grew into longer and longer strokes as they revolved in the swells of the sea; the jib was set out over her sharp nose to steady her, and the column of smoke from her funnel, blown out by the wind, was left, in her speed, upon the larboard quarter, to compare its dark-brown shadow with the white furrow behind. At the beginning of the long summer evening the round moon rose, white and beautiful, opposite the blue peaks of Arran, shining with sunset. By that time the steamer's crowded and lumbered decks had got somewhat settled into order; the splash of the paddles, and the clank of the engine, leaping up and down at the window of its house, kept up a kind of quiet, by contrast, in spite of the different noises going on around. Amongst such, a nuisance apparently inseparable from and peculiar to steamboats, is a blind fiddler, whose everlasting infernal scrape, squeaking away on the foredeck, one cannot help blending with the thump and shudder of those emetic machines on a large scale, and considering it not the least element in producing the disagreeable phenomena so well known on board of them. One of these said floating musicians, who thus wander probably in imitation of Arion, and in revenge for his fate, was now performing to the groups near the paddle-boxes. Beyond them, however, by the steamer's patent iron windlass, there was a quiet space at the bow, where, in a short time, I perceived the figures of the sailors relieved against the brisk sea-view above the insignificant bowsprit. I went forward out of the privileged regions to smoke a cigar, and found the two elder ones sitting over the windlass in conversation with another seafaring passenger, evidently less thoroughbred, however. The rest were walking backwards and forwards to a side, with the quick rolling walk, limited in extent, so characteristic of the genus _nauta_--the negro turning his head now and then to grin as he heard the music, but otherwise above mixing in the rabble of already disconsolate-looking people behind.
