Marvel.

I have often wondered at the extreme fecundity of the press, and how it comes to pass that so many heads, on which Nature seems to have inflicted the curse of barrenness, should teem with voluminous productions. As a man travels on, however, in the journey of life, his objects of wonder daily diminish, and he is continually finding out some very simple cause for some great matter of marvel. Thus have I chanced, in my peregrinations about this great metropolis, to blunder upon a scene which unfolded to me some of the mysteries of the book-making craft, and at once put an end to my astonishment.

I was one summer's day loitering through the great saloons of the British Museum, with that listlessness with which one is apt to saunter about a museum in warm weather; sometimes lolling over the glass cases of minerals, sometimes studying the hieroglyphics on an Egyptian mummy, and some times trying, with nearly equal success, to comprehend the allegorical paintings on the lofty ceilings. Whilst I was gazing about in this idle way, my attention was attracted to a distant door, at the end of a suite of apartments. It was closed, but every now and then it would open, and some strange-favored being, generally clothed in black, would steal forth, and glide through the rooms, without noticing any of the surrounding objects. There was an air of mystery about this that piqued my languid curiosity, and I determined to attempt the passage of that strait, and to explore the unknown regions beyond. The door yielded to my hand, with all that facility with which the portals of enchanted castles yield to the adventurous knight-errant. I found myself in a spacious chamber, surrounded with great cases of venerable books. Above the cases, and just under the cornice, were arranged a great number of black-looking portraits of ancient authors. About the room were placed long tables, with stands for reading and writing, at which sat many pale, studious personages, poring intently over dusty volumes, rummaging among mouldy manuscripts, and taking copious notes of their contents. A hushed stillness reigned through this mysterious apartment, excepting that you might hear the racing of pens over sheets of paper, and occasionally the deep sigh of one of these sages, as he shifted his position to turn over the page of an old folio; doubtless arising from that hollowness and flatulency incident to learned research.
