| "long precisely --having little or no money in my purse, and nothing particular", |
| "to interest me on shore, I thought I would sail about a little and see the", |
| "watery part of the world. It is a way I have of driving off the spleen, and", |
| "regulating the circulation. Whenever I find myself growing grim about the", |

| "myself involuntarily pausing before coffin warehouses, and bringing up the", |

| "upper hand of me, that it requires a strong moral principle to prevent me", |
| "from deliberately stepping into the street, and methodically knocking", |
| "people's hats off--then, I account it high time to get to sea as soon as I can.", |
| "", |
| "This is my substitute for pistol and ball. With a philosophical flourish", |
| "Cato throws himself upon his sword; I quietly take to the ship. There is", |
| "nothing surprising in this. If they but knew it, almost all men in their", |
| "degree, some time or other, cherish very nearly the same feelings towards the", |
| "ocean with me. There now is your insular city of the Manhattoes, belted round", |
| "by wharves as Indian isles by coral reefs--commerce surrounds it with her surf.", |
| "", |
| "Right and left, the streets take you waterward. Its extreme down-town is", |
| "the battery, where that noble mole is washed by waves, and cooled by", |
| "breezes, which a few hours previous were out of sight of land. Look at the", |
| "crowds of water-gazers there. Circumambulate the city of a dreamy Sabbath", |
| "afternoon. Go from Corlears Hook to Coenties Slip, and from thence, by", |
| "Whitehall northward. What do you see?--Posted like silent sentinels all", |
| "around the town, stand thousands upon thousands of mortal men fixed in ocean", |
| "reveries. Some leaning against the spiles; some seated upon the pier-heads;", |
| "some looking over the bulwarks glasses!", |
| "of ships from China; some high aloft in the rigging, as if striving to get a", |
| "still better seaward peep. But these are all landsmen; of week days pent up", |
| "in lath and plaster--tied to counters, nailed to benches, clinched to desks.", |
| "How then is this? Are the green fields gone? What do they here? But look!", |
| "here come more crowds, pacing straight for the water, and seemingly bound for", |
| "a dive. Strange! Nothing will content them but the extremest limit of the", |
| "land; loitering under the shady lee of yonder warehouses will not suffice.", |
| "No. They must get just as nigh the water as they possibly can without falling", |
| "in. And there they stand--miles of them--leagues. Inlanders all, they come", |
| "from lanes and alleys, streets and avenues, --north, east, south, and west.", |
| "Yet here they all unite. Tell me, does the magnetic virtue of the needles of", |
| "the compasses of all those ships attract them thither? Once more. Say, you", |
| "are in the country; in some high land of lakes. Take almost any path you", |
| "please, and ten to one it carries you down in a dale, and leaves you there", |
| "by a pool in the stream. There is magic in it. Let the most absent-minded", |
| "of men be plunged in his deepest reveries--stand that man on his legs, set his", |
| "feet a-going, and he will infallibly lead you to water, if water there be in", |
| "all that region. Should you ever be athirst in the great American desert,", |
| "try this experiment, if your caravan happen to be supplied with a metaphysical", |
| "professor. Yes, as every one knows, meditation and water are wedded for ever.", |
| "", |
| "But here is an artist. He desires to paint you the dreamiest, shadiest,", |
| "quietest, most enchanting bit of romantic landscape in all the valley of the", |
| "Saco. What is the chief element he employs? There stand his trees, each with", |
| "a hollow trunk, as if a hermit and a crucifix were within; and here sleeps", |
| "his meadow, and there sleep his cattle; and up from yonder cottage goes a", |
| "sleepy smoke. Deep into distant woodlands winds a mazy way, reaching to", |
| "overlapping spurs of mountains bathed in their hill-side blue. But though", |
| "the picture lies thus tranced, and though this pine-tree shakes down its sighs", |
| "like leaves upon this shepherd's head, yet all were vain, unless the", |
| "shepherd's eye were fixed upon the magic stream before him. Go visit the", |
| "Prairies in June,", |
| "", |
| "when for scores on scores of miles you wade knee-deep among Tiger-lilies--what", |
| "is the one charm wanting? --Water --there is not a drop of water there! Were", |
| "Niagara but a cataract of sand, would you travel your thousand miles to see", |
| "it? Why did the poor poet of Tennessee, upon suddenly receiving two handfuls", |
| "of silver, deliberate whether to buy him a coat, which he sadly needed, or", |
| "invest his money in a pedestrian trip to Rockaway Beach? Why is almost every", |
| "robust healthy boy with a robust healthy soul in him, at some time or other", |
| "crazy to go to sea? Why upon your first voyage as a passenger, did you", |
| "yourself feel such a mystical vibration, when first told that you and your", |
| "ship were now out of sight of land? Why did the old Persians hold the sea", |
| "holy? Why did the Greeks give it a separate deity, and own brother of Jove?", |
| "Surely all this is not without meaning. And still deeper the meaning of that", |
| "story of Narcissus, who because he could not grasp the tormenting, mild image", |
| "he saw in the fountain, plunged into it and was drowned. But that same", |
| "image, we ourselves see in all rivers and oceans. It is the image of the", |
| "ungraspable phantom of life; and this is the key to it all. Now, when I say", |
| "that I am in the habit of going to sea whenever I begin to grow hazy about the", |
| "eyes, and begin to be over conscious of my lungs, I do not mean to have it", |
| "inferred that I ever go to sea as a passenger. For to go as a passenger you", |
| "must needs have a purse, and a purse is but a rag unless you have something", |
| "in it. Besides, passengers get sea-sick --grow quarrelsome --don't sleep of", |
| "nights --do not enjoy themselves much, as a general thing; --no, I never go as a", |
| "passenger; nor, though I am something of a salt, do I ever go to sea as a", |
| "Commodore, or a Captain, or a Cook. I abandon the glory and distinction of", |
| "such offices to those who like them. For my part, I abominate all honorable", |
| "respectable toils, trials, and tribulations of every kind whatsoever. It is", |
| "quite as much as I can do to take care of myself, without taking care of", |
| "ships, barques, brigs, schooners, and what not. And as for going as cook, --", |
| "though I confess there is considerable glory in that, a cook being a sort of", |
| "officer on ship-board --yet, somehow, I never fancied broiling fowls; --though", |
| "once broiled, judiciously buttered, and judgmatically salted and peppered,", |
| "there is no one who will", |
| "", |
| "speak more respectfully, not to say reverentially, of a broiled fowl than I", |
| "will. It is out of the idolatrous dotings of the old Egyptians upon broiled", |
| "ibis and roasted river horse, that you see the mummies of those creatures in", |
| "their huge bake-houses the pyramids. No, when I go to sea, I go as a simple", |
| "sailor, right before the mast, plumb down into the forecastle, aloft there", |
| "to the royal mast-head. True, they rather order me about some, and make me", |
| "jump from spar to spar, like a grasshopper in a May meadow. And at first,", |
| "this sort of thing is unpleasant enough. It touches one's sense of honor,", |
| "particularly if you come of an old established family in the land, the van", |
| "Rensselaers, or Randolphs, or Hardicanutes. And more than all, if just", |
| "previous to putting your hand into the tar-pot, you have been lording it as a", |
| "country schoolmaster, making the tallest boys stand in awe of you. The", |
| "transition is a keen one, I assure you, from the schoolmaster to a sailor,", |
| "and requires a strong decoction of Seneca and the Stoics to enable you to grin", |
| "and bear it. But even this wears off in time. What of it, if some old hunks", |
| "of a sea-captain orders me to get a broom and sweep down the decks? What does", |
| "that indignity amount to, weighed, I mean, in the scales of the New", |
| "Testament? Do you think the archangel Gabriel thinks anything the less of me,", |
| "because I promptly and respectfully obey that old hunks in that particular", |
| "instance? Who aint a slave? Tell me that. Well, then, however the old", |
| "sea-captains may order me about--however they may thump and punch me about, I", |
| "have the satisfaction of knowing that it is all right; that everybody else", |
| "is one way or other served in much the same way -- either in a physical or", |
| "metaphysical point of view, that is; and so the universal thump is passed", |
| "round, and all hands should rub each other's shoulder-blades, and be", |
| "content. Again, I always go to sea as a sailor, because they make a point of", |
| "paying me for my trouble, whereas they never pay passengers a single penny", |
| "that I ever heard of. On the contrary, passengers themselves must pay. And", |
| "there is all the difference in the world between paying and being paid. The", |
| "act of paying is perhaps the most uncomfortable infliction that the two", |
| "orchard thieves entailed upon us." |
