When soot is first collected, it is called "rough soot", which, being sifted, is then called "fine soot", and is sold to farmers for manuring and preserving wheat and turnips. This is more especially used in Herefordshire, Bedfordshire, Essex, &c. It is rather a costly article, being fivepence per bushel. One contractor sells annually as much as three thousand bushels; and he gives it as his opinion, that there must be at least one hundred and fifty times this quantity (four hundred and fifty thousand bushels per annum) sold in London. Farmer Smutwise, of Bradford, distinctly asserts that the price of the soot he uses on his land is returned to him in the straw, with improvement also to the grain. And we believe him. Lime is used to dilute soot when employed as a manure. Using it pure will keep off snails, slugs, and caterpillars from peas and various other vegetables, as also from dahlias just shooting up, and other flowers; but we regret to add that we have sometimes known it kill or burn up the things it was intended to preserve from unlawful eating. In short, it is by no means so safe to use for any purpose of garden manure, as fine cinders and wood-ashes, which are good for almost any kind of produce, whether turnips or roses. Indeed, we should like to have one fourth or fifth part of our garden-beds composed of excellent stuff of this kind. From all that has been said, it will have become very intelligible why these Dust-heaps are so valuable. Their worth, however, varies not only with their magnitude, (the quality of all of them is much the same,) but with the demand. About the year 1820, the Marylebone Dust-heap produced between four thousand and five thousand pounds. In 1832, St. George's paid Mr. Stapleton five hundred pounds a year, not to leave the Heap standing, but to carry it away. Of course he was only too glad to be paid highly for selling his Dust.
But to return. The three friends having settled to their satisfaction the amount of money they should probably obtain by the sale of the golden miniature-frame, and finished the castles which they had built with it in the air, the frame was again infolded in the sound part of the parchment, the rags and rottenness of the law were cast away, and up they rose to bend their steps homeward to the little hovel where Peggy lived, she having invited the others to tea, that they might talk yet more fully over the wonderful good luck that had befallen them.
