It will be seen, likewise, that this Custom-House sketch has a certain propriety, of a kind always recognised in literature, as explaining how a large portion of the following pages came into my possession, and as offering proofs of the authenticity of a narrative therein contained. This, in fact--a desire to put myself in my true position as editor, or very little more, of the most prolix among the tales that make up my volume--this, and no other, is my true reason for assuming a personal relation with the public. In accomplishing the main purpose, it has appeared allowable, by a few extra touches, to give a faint representation of a mode of life not heretofore described, together with some of the characters that move in it, among whom the author happened to make one.

In my native town of Salem, at the head of what, half a century ago, in the days of old King Derby, was a bustling wharf--but which is now burdened with decayed wooden warehouses, and exhibits few or no symptoms of commercial life; except, perhaps, a bark or brig, half-way down its melancholy length, discharging hides; or, nearer at hand, a Nova Scotia schooner, pitching out her cargo of firewood--at the head, I say, of this dilapidated wharf, which the tide often overflows, and along which, at the base and in the rear of the row of buildings, the track of many languid years is seen in a border of unthrifty grass--here, with a view from its front windows adown this not very enlivening prospect, and thence across the harbour, stands a spacious edifice of brick. From the loftiest point of its roof, during precisely three and a half hours of each forenoon, floats or droops, in breeze or calm, the banner of the republic; but with the thirteen stripes turned vertically, instead of horizontally, and thus indicating that a civil, and not a military, post of Uncle Sam's government is here established. Its front is ornamented with a portico of half-a-dozen wooden pillars, supporting a balcony, beneath which a flight of wide granite steps descends towards the street. Over the entrance hovers an enormous specimen of the American eagle, with outspread wings, a shield before her breast, and, if I recollect aright, a bunch of intermingled thunderbolts and barbed arrows in each claw. With the customary infirmity of temper that characterizes this unhappy fowl, she appears by the fierceness of her beak and eye, and the general truculency of her attitude, to threaten mischief to the inoffensive community; and especially to warn all citizens careful of their safety against intruding on the premises which she overshadows with her wings. Nevertheless, vixenly as she looks, many people are seeking at this very moment to shelter themselves under the wing of the federal eagle; imagining, I presume, that her bosom has all the softness and snugness of an eiderdown pillow. But she has no great tenderness even in her best of moods, and, sooner or later--oftener soon than late--is apt to fling off her nestlings with a scratch of her claw, a dab of her beak, or a rankling wound from her barbed arrows.
