In a subsequent tour of observation, I encountered another of these relics of a 'foregone world' locked up in the heart of the city. I had been wandering for some time through dull monotonous streets, destitute of any thing to strike the eye or excite the imagination, when I beheld before me a Gothic gateway of mouldering antiquity. It opened into a spacious quadrangle forming the court-yard of a stately Gothic pile, the portal of which stood invitingly open.
    It was apparently a public edifice, and as I was antiquity hunting, I ventured in, though with dubious steps. Meeting no one either to oppose or rebuke my intrusion, I continued on until I found myself in a great hall, with a lofty arched roof and oaken gallery, all of Gothic architecture. At one end of the hall was an enormous fireplace, with wooden settles on each side; at the other end was a raised platform, or dais, the seat of state, above which was the portrait of a man in antique garb, with a long robe, a ruff, and a venerable gray beard.
    The whole establishment had an air of monastic quiet and seclusion, and what gave it a mysterious charm, was, that I had not met with a human being since I had passed the threshold.
    Encouraged by this loneliness, I seated myself in a recess of a large bow window, which admitted a broad flood of yellow sunshine, checkered here and there by tints from panes of colored glass; while an open casement let in the soft summer air. Here, leaning my head on my hand, and my arm on an old oaken table, I indulged in a sort of reverie about what might have been the ancient uses of this edifice. It had evidently been of monastic origin; perhaps one of those collegiate establishments built of yore for the promotion of learning, where the patient monk, in the ample solitude of the cloister, added page to page and volume to volume, emulating in the production of his brain the magnitude of the pile he inhabited.
    As I was seated in this musing mood, a small panelled door in an arch at the upper end of the hall was opened, and a number of gray-headed old men, clad in long black cloaks, came forth one by one; proceeding in that manner through the hall, without uttering a word, each turning a pale face on me as he passed, and disappearing through a door at the lower end.
    I was singularly struck with their appearance; their black cloaks and antiquated air comported with the style of this most venerable and mysterious pile. It was as if the ghosts of the departed years, about which I had been musing, were passing in review before me. Pleasing myself with such fancies, I set out, in the spirit of romance, to explore what I pictured to myself a realm of shadows, existing in the very centre of substantial realities.    
    My ramble led me through a labyrinth of interior courts, and corridors, and dilapidated cloisters, for the main edifice had many additions and dependencies, built at various times and in various styles; in one open space a number of boys, who evidently belonged to the establishment, were at their sports; but everywhere I observed those mysterious old gray men in black mantles, sometimes sauntering alone, sometimes conversing in groups: they appeared to be the pervading genii of the place. I now called to mind what I had read of certain colleges in old times, where judicial astrology, geomancy, necromancy, and other forbidden and magical sciences were taught. Was this an establishment of the kind, and were these black-cloaked old men really professors of the black art?
    These surmises were passing through my mind as my eye glanced into a chamber, hung round with all kinds of strange and uncouth objects; implements of savage warfare; strange idols and stuffed alligators; bottled serpents and monsters decorated the mantelpiece; while on the high tester of an old-fashioned bedstead grinned a human skull, flanked on each side by a dried cat.
    I approached to regard more narrowly this mystic chamber, which seemed a fitting laboratory for a necromancer, when I was startled at beholding a human countenance staring at me from a dusky corner. It was that of a small, shrivelled old man, with thin cheeks, bright eyes, and gray wiry projecting eyebrows. I at first doubted whether it were not a mummy curiously preserved, but it moved, and I saw that it was alive. It was another of these black-cloaked old men, and, as I regarded his quaint physiognomy, his obsolete garb, and the hideous and sinister objects by which he was surrounded, I began to persuade myself that I had come upon the arch mago, who ruled over this magical fraternity.
    Seeing me pausing before the door, he rose and invited me to enter. I obeyed, with singular hardihood, for how did I know whether a wave of his wand might not metamorphose me into some strange monster, or conjure me into one of the bottles on his mantelpiece? He proved, however, to be any thing but a conjurer, and his simple garrulity soon dispelled all the magic and mystery with which I had enveloped this antiquated pile and its no less antiquated inhabitants.
    It appeared that I had made my way into the centre of an ancient asylum for superannuated tradesmen and decayed householders, with which was connected a school for a limited number of boys. It was founded upwards of two centuries since on an old monastic establishment, and retained somewhat of the conventual air and character. The shadowy line of old men in black mantles who had passed before me in the hall, and whom I had elevated into magi, turned out to be the pensioners returning from morning service in the chapel.
    John Hallum, the little collector of curiosities, whom I had made the arch magician, had been for six years a resident of the place, and had decorated this final nestling-place of his old age with relics and rarities picked up in the course of his life. According to his own account he had been somewhat of a traveller; having been once in France, and very near making a visit to Holland. He regretted not having visited the latter country, 'as then he might have said he had been there.'He was evidently a traveller of the simplest kind.
    He was aristocratical too in his notions; keeping aloof, as I found, from the ordinary run of pensioners. His chief associates were a blind man who spoke Latin and Greek, of both which languages Hallum was profoundly ignorant; and a broken-down gentleman who had run through a fortune of forty thousand pounds left him by his father, and ten thousand pounds, the marriage portion of his wife. Little Hallum seemed to consider it an indubitable sign of gentle blood as well as of lofty spirit to be able to squander such enormous sums.
    P.S. The picturesque remnant of old times into which I have thus beguiled the reader is what is called the Charter House, originally the Chartreuse. It was founded in 1611, on the remains of an ancient convent, by Sir Thomas Sutton, being one of those noble charities set on foot by individual munificence, and kept up with the quaintness and sanctity of ancient times amidst the modern changes and innovations of London. Here eighty broken-down men, who have seen better days, are provided, in their old age, with food, clothing, fuel, and a yearly allowance for private expenses. They dine together as did the monks of old, in the hall which had been the refectory of the original convent. Attached to the establishment is a school for forty-four boys.
    Stow, whose work I have consulted on the subject, speaking of the obligations of the gray-headed pensioners, says, 'They are not to intermeddle with any business touching the affairs of the hospital, but to attend only to the service of God, and take thankfully what is provided for them, without muttering, murmuring, or grudging. None to wear weapon, long hair, colored boots, spurs or colored shoes, feathers in their hats, or any ruffian-like or unseemly apparel, but such as becomes hospital men to wear.' 'And in truth,' adds Stow, 'happy are they that are so taken from the cares and sorrows of the world, and fixed in so good a place as these old men are; having nothing to care for, but the good of their souls, to serve God and to live in brotherly love.' 
    For the amusement of such as have been interested by the preceding sketch, taken down from my own observation, and who may wish to know a little more about the mysteries of London, I subjoin a modicum of local history, put into my hands by an odd-looking old gentleman in a small brown wig and a snuff-colored coat, with whom I became acquainted shortly after my visit to the Charter House. I confess I was a little dubious at first, whether it was not one of those apocryphal tales often passed off upon inquiring travellers like myself; and which have brought our general character for veracity into such unmerited reproach. On making proper inquiries, however, I have received the most satisfactory assurances of the author's probity; and, indeed, have been told that he is actually engaged in a full and particular account of the very interesting region in which he resides; of which the following may be considered merely as a foretaste.
