Note 67 — Of the London Chimney-Sweepers. (continued 5)

The following note appears in Mr. Fortescue’s statement:—“In some trial works near the metropolis sewer water was applied to land, on the condition that the value of half the extra crop should be taken as payment. The dressings were only single dressings. The officer making the valuation reported, that there was at the least one sack of wheat and one load of straw per acre extra from its application on one breadth of land; in another, full one quarter of wheat more, and one load of straw extra per acre. The reports of the effects of sewer-water in increasing the yield of oats as well as of wheat were equally good. It is stated by Captain Vetch that in South America irrigation is used with great advantage for wheat.”
