cured for bacon. They are first rubbed with salt on their insides, or flesh sides, then placed one on the other, the flesh sides uppermost, in a salting-trough which has a gutter round its edges to drain away the brine; for, to have sweet and fine bacon, the flitches must not be sopping in brine, which gives it the sort of vile taste that barrel and sea pork have. Every one knows how different is the taste of fresh dry salt from that of salt in a dissolved state; therefore change the salt often,--once in 4 or 5 days; let it melt and sink in, but not lie too long; twice change the flitches, put that at bottom which was first on the top: this mode will cost you a great deal more in salt than the sopping mode, but without it your bacon will not be so sweet and fine, nor keep so well. As for the time required in making your flitches sufficiently salt, it depends on circumstances. It takes a longer time for a thick than a thin flitch, and longer in dry than in damp weather, or in a dry than in a damp place; but for the flitches of a hog of five score, in weather not very dry or damp, about 6 weeks may do; and as yours is to be fat, which receives little injury from over-salting, give time enough, for you are to have bacon until Christmas comes again.
