Finally he decided to lay a base of three parallel with the wall, to place upon this two layers of two each, and upon these a single box to serve as the platform. This arrangement could be ascended with a minimum of awkwardness, and would furnish the desired height. Better still, though, he would utilise only two boxes of the base to support the superstructure, leaving one free to be piled on top in case the actual feat of escape required an even greater altitude. And so the prisoner toiled in the twilight, heaving the unresponsive remnants of mortality with little ceremony as his miniature Tower of Babel rose course by course. Several of the coffins began to split under the stress of handling, and he planned to save the stoutly built casket of little Matthew Fenner for the top, in order that his feet might have as certain a surface as possible. In the semi-gloom he trusted mostly to touch to select the right one, and indeed came upon it almost by accident, since it tumbled into his hands as if through some odd volition after he had unwittingly placed it beside another on the third layer.
The tower at length finished, and his aching arms rested by a pause during which he sat on the bottom step of his grim device, Birch cautiously ascended with his tools and stood abreast of the narrow transom. The borders of the space were entirely of brick, and there seemed little doubt but that he could shortly chisel away enough to allow his body to pass. As his hammer blows began to fall, the horse outside whinnied in a tone which may have been encouraging and to others may have been mocking. In either case it would have been appropriate; for the unexpected tenacity of the easy-looking brickwork was surely a sardonic commentary on the vanity of mortal hopes, and the source of a task whose performance deserved every possible stimulus.
Dusk fell and found Birch still toiling. He worked largely by feeling now, since newly gathered clouds hid the moon; and though progress was still slow, he felt heartened at the extent of his encroachments on the top and bottom of the aperture. He could, he was sure, get out by midnight– though it is characteristic of him that this thought was untinged with eerie implications. Undisturbed by oppressive reflections on the time, the place, and the company beneath his feet, he philosophically chipped away the stony brickwork; cursing when a fragment hit him in the face, and laughing when one struck the increasingly excited horse that pawed near the cypress tree. In time the hole grew so large that he ventured to try his body in it now and then, shifting about so that the coffins beneath him rocked and creaked. He would not, he found, have to pile another on his platform to make the proper height; for the hole was on exactly the right level to use as soon as its size might permit.
It must have been midnight at least when Birch decided he could get through the transom. Tired and perspiring despite many rests, he descended to the floor and sat a while on the bottom box to gather strength for the final wriggle and leap to the ground outside. The hungry horse was neighing repeatedly and almost uncannily, and he vaguely wished it would stop. He was curiously unelated over his impending escape, and almost dreaded the exertion, for his form had the indolent stoutness of early middle age. As he remounted the splitting coffins he felt his weight very poignantly; especially when, upon reaching the topmost one, he heard that aggravated crackle which bespeaks the wholesale rending of wood. He had, it seems, planned in vain when choosing the stoutest coffin for the platform; for no sooner was his full bulk again upon it than the rotting lid gave way, jouncing him two feet down on a surface which even he did not care to imagine. Maddened by the sound, or by the stench which billowed forth even to the open air, the waiting horse gave a scream that was too frantic for a neigh, and plunged madly off through the night, the wagon rattling crazily behind it.
Birch, in his ghastly situation, was now too low for an easy scramble out of the enlarged transom; but gathered his energies for a determined try. Clutching the edges of the aperture, he sought to pull himself up, when he noticed a queer retardation in the form of an apparent drag on both his ankles. In another moment he knew fear for the first time that night; for struggle as he would, he could not shake clear of the unknown grasp which held his feet in relentless captivity. Horrible pains, as of savage wounds, shot through his calves; and in his mind was a vortex of fright mixed with an unquenchable materialism that suggested splinters, loose nails, or some other attribute of a breaking wooden box. Perhaps he screamed. At any rate he kicked and squirmed frantically and automatically whilst his consciousness was almost eclipsed in a half-swoon.
Instinct guided him in his wriggle through the transom, and in the crawl which followed his jarring thud on the damp ground. He could not walk, it appeared, and the emerging moon must have witnessed a horrible sight as he dragged his bleeding ankles toward the cemetery lodge; his fingers clawing the black mould in brainless haste, and his body responding with that maddening slowness from which one suffers when chased by the phantoms of nightmare. There was evidently, however, no pursuer; for he was alone and alive when Armington, the lodge-keeper, answered his feeble clawing at the door.
Armington helped Birch to the outside of a spare bed and sent his little son Edwin for Dr. Davis. The afflicted man was fully conscious, but would say nothing of any consequence; merely muttering such things as "Oh, my ankles!", "Let go!", or "Shut in the tomb". Then the doctor came with his medicine-case and asked crisp questions, and removed the patient's outer clothing, shoes, and socks. The wounds– for both ankles were frightfully lacerated about the Achilles' tendons– seemed to puzzle the old physician greatly, and finally almost to frighten him. His questioning grew more than medically tense, and his hands shook as he dressed the mangled members; binding them as if he wished to get the wounds out of sight as quickly as possible.
For an impersonal doctor, Davis ' ominous and awestruck cross-examination became very strange indeed as he sought to drain from the weakened undertaker every least detail of his horrible experience. He was oddly anxious to know if Birch were sure– absolutely sure– of the identity of that top coffin of the pile; how he had chosen it, how he had been certain of it as the Fenner coffin in the dusk, and how he had distinguished it from the inferior duplicate coffin of vicious Asaph Sawyer. Would the firm Fenner casket have caved in so readily? Davis, an old-time village practitioner, had of course seen both at the respective funerals, as indeed he had attended both Fenner and Sawyer in their last illnesses. He had even wondered, at Sawyer's funeral, how the vindictive farmer had managed to lie straight in a box so closely akin to that of the diminutive Fenner.
After a full two hours Dr. Davis left, urging Birch to insist at all times that his wounds were caused entirely by loose nails and splintering wood. What else, he added, could ever in any case be proved or believed? But it would be well to say as little as could be said, and to let no other doctor treat the wounds. Birch heeded this advice all the rest of his life till he told me his story; and when I saw the scars– ancient and whitened as they then were– I agreed that he was wise in so doing. He always remained lame, for the great tendons had been severed; but I think the greatest lameness was in his soul. His thinking processes, once so phlegmatic and logical, had become ineffaceably scarred; and it was pitiful to note his response to certain chance allusions such as "Friday", "Tomb", "Coffin", and words of less obvious concatenation. His frightened horse had gone home, but his frightened wits never quite did that. He changed his business, but something always preyed upon him. It may have been just fear, and it may have been fear mixed with a queer belated sort of remorse for bygone crudities. His drinking, of course, only aggravated what it was meant to alleviate.
