the great depth at which the passage of the river commences.  Descending a wearisome succession of staircases, we at last find ourselves, still in the broad noon, standing before a closed door, on opening which we behold the vista of an arched corridor that extends into everlasting midnight.  In these days, when glass has been applied to so many new purposes, it is a pity that the architect had not thought of arching portions of his abortive tunnel with immense blocks of the lucid substance, over which the dusky Thames would have flowed like a cloud, making the sub-fluvial avenue only a little gloomier than a street of upper London.  At present, it is illuminated at regular intervals by jets of gas, not very brilliantly, yet with lustre enough to show the damp plaster of the ceiling and walls, and the massive stone pavement, the crevices of which are oozy with moisture, not from the incumbent river, but from hidden springs in the earth’s deeper heart.  There are two parallel corridors, with a wall between, for the separate accommodation of the double throng of foot-passengers, equestrians, and vehicles of all kinds, which was expected to roll and reverberate continually through the Tunnel.  Only one of them has ever been opened, and its echoes are but feebly awakened by infrequent footfalls.

Yet there seem to be people who spend their lives here, and who probably blink like owls, when, once or twice a year, perhaps, they happen to climb into the sunshine.  All along the corridor, which I believe to be a mile in extent, we see stalls or shops in little alcoves, kept principally by women; they were of a ripe age, I was glad to observe, and certainly robbed England of none of its very moderate supply of feminine loveliness by their deeper than tomb-like interment.  As you approach, (and they are so accustomed to the dusky gas-light that they read all your characteristics afar off,) they assail you with hungry entreaties to buy some of their merchandise, holding forth views of the Tunnel put up in cases of Derbyshire spar, with a magnifying-glass at one end to make the vista more effective.  They offer you, besides, cheap jewelry, sunny topazes and resplendent emeralds for sixpence, and diamonds as big as the Koh-i-noor at a not much heavier cost, together with a multifarious trumpery which has died out of the upper world to reappear in this Tartarean bazaar.  That you may fancy yourself still in the realms of the living, they urge you to partake of cakes, candy, ginger-beer, and such small refreshment, more suitable, however, for the shadowy appetite of ghosts than for the sturdy stomachs of Englishmen.  The most capacious of the shops contains a dioramic exhibition of cities and scenes in the daylight-world, with a dreary glimmer of gas among them all; so that they serve well enough to represent the dim, unsatisfactory remembrances that dead people might be supposed to retain from their past lives, mixing them up with the ghastliness of their unsubstantial state.  I dwell the more upon these trifles, and do my best to give them a mockery of importance, because, if these are nothing, then all this elaborate contrivance and mighty piece of work has been wrought in vain.  The Englishman has burrowed under the bed of his great river, and set ships of two or three thousand tons a-rolling over his head, only to provide new sites for a few old women to sell cakes and ginger-beer!
