Proceeding down the dock-yard, you see before you a large area literally paved with wine-casks, all full of the most excellent wines. On our last visit, the wine then covering the ground was delicious Bordeaux, as you might easily convince yourself by dipping a finger into the bunghole of any cask; as, for some purpose of measurement, or testing the quality, the casks were most of them open. This is, in fact, the great depôt of the wine of the London merchants, no less than sixty thousand pipes being capable of being stored away in the vaults here. One vault alone, which formerly was seven acres, has now been extended under Gravel-lane, so that at present it contains upward of twelve acres! These vaults are faintly lit with lamps, but on going in, you are at the entrance accosted with the singular demand--"Do you want a cooper?" Many people, not knowing its meaning, say, "No, by no means!" The meaning of the phrase is, "do you want to taste the wines?" when a cooper accompanies you to pierce the casks, and give you the wine. Parties are every day, and all day long, making these exploratory and tasting expeditions. Every one on entering is presented with a lamp at the end of a lath, about two feet long, and you soon find yourselves in some of the most remarkable caving in the world. Small streets, which you perceive are of great extent, by the glimmering of lamps in the far distance, extend before you, and are crossed by others in such a manner that none but those well acquainted with the geography of these subterranean regions could possibly find their way about them. From the dark vaulted roof over head, especially in one vault, hang strange figures, black as night, light as gossamer, and of a yard or more in length, resembling skins of beasts, or old shirts dipped in soot. These are fed to this strange growth by the fumes of the wine. For those who taste the wines the cooper bores the heads of the pipes, which are ranged throughout these vast cellars on either hand in thousands and tens of thousands, and draws a glassful. These glasses, though shaped as wine-glasses, resemble much more goblets in their size, containing each as much as several ordinary wine-glasses. What you do not drink is thrown upon the ground; and it is calculated that at least a hogshead a day is thus consumed. Many parties who wish for a cheap carouse, procure a tasting order, take biscuits with them, and drink of the best of all sorts of wine in the cellars, and in quantities enough to terrify any disciple of Father Mathew. Here, again, we find a regulation permitting no ladies to enter these cellars after one o'clock. For such a rule there must be a sufficient cause, and the fact which we have just stated may perhaps furnish the key to it.
