When the poor untutored Indians, from the soft and simple prairies of the Missouri, seated themselves upon a beam, and were looking into and contemplating the immensity of a smoking steeping-vat, containing more than 3000 barrels, and were told that there were 130 others of various dimensions in the establishment--that the whole edifice covered twelve acres of ground, and that there were necessarily constantly on hand in their cellars 232,000 barrels of ale, and also that this was only one of a great number of breweries in London, and that similar manufactories were in every town in the kingdom, though on a less scale, they began, almost for the first time since their arrival, to evince profound astonishment; and the fermentation in their minds, as to the consistency of white man's teachings of temperance and manufacturing and selling ale, seemed not less than that which was going on in the vast abyss below them. The pipe was lit and passed around while they were in this contemplative mood, and as their ears were open, they got, in the meantime, further information of the wonderful modes and operations of this vast machine; and also, in round numbers, read from a report by one of the proprietors, the quantity of ale consumed in the kingdom annually. Upon hearing this, which seemed to cap the climax of all their astonishment, they threw down the pipe, and leaping into an empty vat, suddenly dissipated the pain of their mental calculations by joining in the Medicine (_or Mystery_) Dance. Their yells and screaming echoing through the vast and vapouring halls, soon brought some hundreds of maltsmen, grinders, firers, mashers, ostlers, painters, coopers, &c., peeping through and amongst the blackened timbers and casks, and curling and hissing fumes, completing the scene as the richest model for the infernal regions. Every reader will paint (and _must_ paint) this picture for himself, imagining the steeping vapour everywhere rising in curling clouds of white towards the blackened walls, and timbers, and wheels, and stairways, and arches, and bridges, and casks, and from amongst and between all of these, the blackened faces and glaring eyeballs piercing through the steam, upon the unusual, and to them as yet unaccountable, _fermentation_ going on (to the admiration and amusement of those who were in the secret) in the empty vat!
