A trap-hatch opens at the side of this enclosure, through which the corpses are thrust into the sticking-room, whence the blood flows into tanks beneath, to be sold, together with the hoofs and hair, to the manufacturers of prussiate of potash and Prussian blue.

Thence they are pushed down an inclined plane into a trough containing a thousand gallons of boiling water, and broad enough to take in piggy lengthways.

By the time they have passed down this caldron, they are ready for scraping, for which purpose a large table is joined on to the lower end of the caldron, and on which they are artistically thrown.

Five men stand in a row on each side of the table, armed with scrapers, and, as piggy passes down, he gets scraped cleaner and cleaner, till the last polishes him as smooth as a yearling baby.

Having thus reached the lower end of the table, there are a quantity of hooks fitted to strong wooden arms, which revolve round a stout pillar, and which, in describing the circle, plumb the lower end of the table.
