But, as a rule, when the suggestion is made that local authorities should provide special receptacles for swill, demur is made on the plea that such a procedure must entail further capital expenditure. Yet it can be carried out along very inexpensive lines if attacked in the proper spirit. So far as Liverpool has been concerned it was even found possible to turn a waste article to such account. Among the flotsam and jetsam sent to the corporation depots for disposal were thousands of tins measuring 9 × 9 × 13 inches, originally used for the conveyance of oil to this country. Examination revealed the circumstance that these discarded receptacles could readily be converted into swill-pails, their dimensions and construction admirably adapting them to such a duty. Forthwith they were cleaned, one or two minor alterations carried out, and then painted. The cost of adaptation was less than 1s.--25 cents--per tin. These were then issued to the residents who expressed readiness to co-operate with the efforts of the authorities, and proved a complete success. It has often been advanced by local authorities that the residents will never collaborate in such schemes of segregation at the source, declining to be bothered, but the experience gained at Liverpool does not support such a contention. The inhabitants of the city astride the Mersey responded very promptly to the request to save and segregate their swill, the result being that enormous accumulations of potential and valuable pig-food were secured. Swill supplies being assured, the next step was to handle this waste at the depot, and to prepare it for the piggeries. The City Engineer, Mr. John A. Brodie, M.Inst.C.E., advanced a complete solution to this problem and along economical lines. A number of old pitch boilers and other plant was lying idle at the depot. This was turned out, overhauled, rigged up and coupled up to the steam generating equipment of the destructor. The household swill was cooked in these vessels, and in this manner a first-class pig-food was produced. To ensure the consumption of the swill thus obtained the Corporation installed its own piggeries and poultry runs upon its farms. The swill, while still hot, was conveyed to the piggeries in the municipal motor wagons and doled out. Private pig-raisers were also at liberty to obtain the swill in the heated condition if they cared to fetch it. This facility was readily accepted, inasmuch as it saved the pig-keepers the trouble and time of conducting collection from houses in the conventional manner and then boiling it upon their farms for their animals.
