Not less striking than those cellars is the Mixing House above, where there are vats into which merchants who wish to equalize all their wines of one vintage can have them emptied, and then re-drawn into their casks. The largest of these vats contains twenty-three thousand two hundred and fifty gallons; and to it the famous Heidelburg Tun is a mere keg. But the reader may ask, what have these wine-cellars to do with the Queen's Pipe? It is this: in the centre of the great east vault you come to a circular building without any entrance. It is the root and foundation of the Queen's Pipe. Quitting the vault, and ascending into the warehouse over it, you find that you are in the Great Tobacco Warehouse, called the Queen's Warehouse, because the Government rent the Tobacco Warehouses here for fourteen thousand pounds per annum. This one warehouse has no equal in any other part of the world. It is five acres in extent, and yet it is covered with a roof, the framework of which is of iron, erected, we believe, by Mr. Barry, the architect of the new houses of parliament, and of so light and skillful a construction, that it admits of a view of the whole place; and so slender are the pillars, that the roof seems almost to hang upon nothing. Under this roof is piled a vast mass of tobacco in huge casks, in double tiers; that is, two casks in height. This warehouse is said to hold, when full, twenty-four thousand hogsheads, averaging one thousand two hundred pounds each, and equal to thirty thousand tons of general merchandise. Each cask is said to be worth, duty included, two hundred pounds; giving a sum total of tobacco in this one warehouse, when filled, of four millions, eight hundred thousand pounds in value! Besides this, there is another warehouse of nearly equal size, where finer kinds of tobacco are deposited, many of them in packages of buffalo-hide, marked "Giron," and Manilla for cheroots, in packages of sacking lined with palmetto leaves. There is still another warehouse for cigars, called the Cigar Floor, in which there are frequently one thousand five hundred chests, valued at one hundred pounds each, at an average, or one hundred and fifty thousand pounds in cigars alone.
