The successful conversion of the volume of dust, comprising about 50 per cent. of the aggregate, into a marketable fertiliser, offers a satisfactory solution of a complex and perplexing problem. But when the dust is coarser and yet deficient in “bite” or gritty characteristic, its disposal is not so readily consummated because its possible applications are thereby severely narrowed down in number. Speaking generally, the utilization of the fine dust may be said to present a vexatious question. While it forms an excellent ingredient for a compounded fertilizer, it is not a simple matter to discover an inexpensive, and preferably second, refuse constituent of approved manurial value with which to associate it. The majority of the ingredients advocated as complying with the desired requirement possess too high an independent fertilizing value for such an application. In itself the dust is of very low soil-feeding power, and so active investigation is being pursued in anticipation of the discovery of a satisfactory adjustment to this question. Another enterprising illustration of what can be achieved with domestic, office and warehouse refuse, both organic and inorganic, is extended by the Port of Liverpool. Here, again, the developments to be recorded in this connection are not attributable to the war, although the last-named factor was responsible for the conduct of the reclamatory process upon a more intensive scale. Liverpool is somewhat peculiarly situated among the importing centres of the United Kingdom seeing that it is probably the largest distributing centre for American foodstuffs for this country. Consequently, as is only to be expected, very considerable quantities of food which have suffered such damage during transit or demurrage as to become unfit for human consumption have to be handled. Under the old _régime_ all organic waste of this character was either consigned right away to the destructor, or was perfunctorially treated to be sold as manure. Neither science nor brains was displayed in its disposal. The shortest way out of the difficulty was accepted as being the most effective in the public interests. But Liverpool was not the only port to follow such summary practice. It was common to all ports of the country in greater or lesser degree. The public loses heavily from the observance of such deprecatory measures, especially when it is borne in mind that such traffic runs into tens of thousands of tons during the course of the year. But under pre-war conditions, owing to the plentitude of supplies and the wide distribution of the losses incurred, the financial effect was scarcely felt by the unit of the population.
