The pure-finders meet with a ready market for all the dogs'--dung they are able to collect, at the numerous tanyards in Bermondsey, where they sell it by the stable-bucket full, and get from 8 d. to 10 d. per bucket, and sometimes 1 s. and 1 s. 2 d. for it, according to its quality. The "dry limy-looking sort" fetches the highest price at some yards, as it is found to possess more of the alkaline, or purifying properties; but others are found to prefer the dark moist quality. Strange as it may appear, the preference for a particular kind has suggested to the finders of Pure the idea of adulterating it to a very considerable extent; this is effected by means of mortar broken away from old walls, and mixed up with the whole mass, which it closely resembles; in some cases, however, the mortar is rolled into small balls similar to those found. Hence it would appear, that there is no business or trade, however insignificant or contemptible, without its own peculiar and appropriate tricks.
