In all the thoughts, words, and actions of Squire Headlong, there was a remarkable alacrity of progression, which almost annihilated the interval between conception and execution.  He was utterly regardless of obstacles, and seemed to have expunged their very name from his vocabulary.  His designs were never nipped in their infancy by the contemplation of those trivial difficulties which often turn awry the current of enterprise; and, though the rapidity of his movements was sometimes arrested by a more formidable barrier, either naturally existing in the pursuit he had undertaken, or created by his own impetuosity, he seldom failed to succeed either in knocking it down or cutting his way through it.  He had little idea of gradation:  he saw no interval between the first step and the last, but pounced upon his object with the impetus of a mountain cataract.  This rapidity of movement, indeed, subjected him to some disasters which cooler spirits would have escaped.  He was an excellent sportsman, and almost always killed his game; but now and then he killed his dog.[8.1] Rocks, streams, hedges, gates, and ditches, were objects of no account in his estimation; though a dislocated shoulder, several severe bruises, and two or three narrow escapes for his neck, might have been expected to teach him a certain degree of caution in effecting his transitions.  He was so singularly alert in climbing precipices and traversing torrents, that, when he went out on a shooting party, he was very soon left to continue his sport alone, for he was sure to dash up or down some nearly perpendicular path, where no one else had either ability or inclination to follow.  He had a pleasure boat on the lake, which he steered with amazing dexterity; but as he always indulged himself in the utmost possible latitude of sail, he was occasionally upset by a sudden gust, and was indebted to his skill in the art of swimming for the opportunity of tempering with a copious libation of wine the unnatural frigidity introduced into his stomach by the extraordinary intrusion of water, an element which he had religiously determined should never pass his lips, but of which, on these occasions, he was sometimes compelled to swallow no inconsiderable quantity.  This circumstance alone, of the various disasters that befell him, occasioned him any permanent affliction, and he accordingly noted the day in his pocket-book as a dies nefastus, with this simple abstract, and brief chronicle of the calamity:  Mem.  Swallowed two or three pints of water:  without any notice whatever of the concomitant circumstances.  These days, of which there were several, were set apart in Headlong Hall for the purpose of anniversary expiation; and, as often as the day returned on which the squire had swallowed water, he not only made a point of swallowing a treble allowance of wine himself, but imposed a heavy mulct on every one of his servants who should be detected in a state of sobriety after sunset:  but their conduct on these occasions was so uniformly exemplary, that no instance of the infliction of the penalty appears on record.
