C. process, at an expense of not more than one-fourth of its actual money value. Since the Leicester experiments were concluded, two small experiments have been made at Leammg- ton. About 60,000 gallons were purified. The analyses of the sewage and effluent water are a]jpended to this Eeport. We are somewhat unAvilling to introduce into this Report any valuation of the residuum made from the sewage; but we may mention the facts that two independent analyses give valuations of £3 17s. 3d., and that Dr. Frankland s estimate of a sample allowed to dry ^vithout the necessary addition of acid, whereby a large portion of the ammonia was lost, is (even then) £l 13s. 0|cl. per ton! These facts speak for themselves as to the })rofit to be derived from the process. In an agricultural point of view, it is an acknow- ledged fixct that, in order to retain the full fertilizing- properties of the soil, it is requisite to restore to it all that is so freely given by it. Up to this time the soil has not had fair play, for Ave have been giving to the sea what we have been taking from the land, and trying, at great expense, to supply the defi- ciency by foreign importation. In our process we have aimed at restoring not merely the usual ingre- dients of sewage, but the blood, the most highly 2
