I am sure this language will seem exaggerated to you, but, upon the faith of a lonely man (the captain has turned in, and it is near midnight and a dead calm), it is a mere skeleton, a goldsmith's inventory, of the reality. I long ago learned that first lesson of a man of the world, "to be astonished at nothing," but the sea has overreached my philosophy--quite. I am changed to a mere child in my wonder. Be assured, no view of the ocean from land can give you a shadow of an idea of it. Within even the outermost Capes, the swell is broken, and the color of the water in soundings is essentially different--more dull and earthy. Go to the mineral cabinets of Cambridge or New Haven, and look at the _fluor spars_, and the _turquoises_, and the clearer specimens of _crysoprase_, and _quartz_, and _diamond_, and imagine them all polished and clear, and flung at your feet by millions in a noonday sun, and it may help your conceptions of the sea after a storm. You may "swim on bladders" at Nahant and Rockaway till you are gray, and be never the wiser. The "middle watch" is called, and the second mate, a fine rough old sailor, promoted from "the mast," is walking the quarter-deck, stopping his whistle now and then with a gruff "How do you head?" or "keep her up, you lubber," to the man at the helm; the "silver-shell" of a waning moon, is just visible through the dead lights over my shoulder (it has been up two hours, to me, and by the difference of our present merideans, is just rising now over a certain hill, and peeping softly in at an eastern window that I have watched many a time when its panes have been silvered by the same chaste alchymy), and so after a walk on the deck for an hour to look at the stars and watch the phosphorus in the wake, I think of ----, I'll get to mine own uneven pillow, and sleep too. LETTER II. AT SEA, OCTOBER 20.--We have had fine weather for progress, so far, running with north and north-westerly winds from eight to ten knots an hour, and making, of course, over two hundred miles a day. The sea is still rough; and though the brig is light laden and rides very buoyantly, these mounting waves break over us now and then with a tremendous surge, keeping the decks constantly wet, and putting me to many an uncomfortable shiver. I have become reconciled, however, to much that I should have anticipated with no little horror. I can lie in my berth forty-eight hours, if the weather is chill or rainy, and amuse myself very well with talking bad French across the cabin to the captain, or laughing at the distresses of my friend and fellow-passenger, Turk (a fine setter dog, on his first voyage), or inventing some disguise for the peculiar flavor which that dismal cook gives to all his abominations, or, at worst, I can bury my head in my pillow, and brace from one side to the other against the swell, and enjoy my disturbed thoughts--all without losing my temper, or wishing that I had not undertaken the voyage.
