    simple and applicable, requiring only very small alteration in the existing arrangements of most sewered towns. In some respects the circumstances of Leicester are peculiar, the sewage has all to be pumped from a considerable depth below the surface. In the majority of instances this would be unnecessary, and the mechanical arrangements would be much simplified. It is only necessary to allow the com- pound to flow in at a regulated rate, and to cause an intimate admixture by an agitator. Independently of the sanitary point of view, this question is of considerable importance in both a financial and agricultural sense—for whereas none of the other processes can be carried on Avithout considerable pressure upon the ratepayers, the A. B. C. plan promises to be a source of revenue. Unlike the lime process, which, by dissipating the ammonia into the air, leaves a worthless deposit, the A. B. C. system retains the fertilizing properties of the sewage ; and unlike irrigation, which involves the serious responsibility and expense of leasing large tracts of land, it promises considerable re- venue with but little outlay of capital. There is not one of the ingredients, excepting the perchloride of iron, that does not positively add to its as^ricultural value, and therefore the residuum possesses, as the analysis shows, a character closely resembling guano, and eminently adapted to farming purposes.
