The foregoing figures may be accepted as moderate. Thus the cinders, with a heating value equal to five-sevenths of that of good steam coal, are priced at 10s.--$2.50--per ton. But, as experience has proved, they readily command 14s.--$3.50--per ton, providing, in their washed condition, a first-class, clean, cheap and economical fuel for the poorer classes of the community. At 10s.--$2.50--per ton they are equal to coal costing 14s.--$3.50--per ton, at which price such fuel is absolutely impossible to-day. Even coke cannot be purchased at double the figure. In other words, by buying washed cinders at the prices quoted the purchaser is receiving a fuel equal, if not superior, to contemporary household coal costing 35s. to 50s.--$7 to $10--per ton. Again, the tins are assessed at a low scrap-metal value. Probably 50 per cent. of the tins rescued from the dust-bin to-day coincide with the term “bright,” and thus would pay to turn into tin-plate. The quotation for this material ignores the value of the solder, as well as that ruling for other metals, such as brass and copper, and of which far more is recovered from the ash-barrel than may be popularly imagined. The figure given, moreover, represents the official price, but since the removal of control scrap-metal has recorded higher quotations. So far as the other materials are concerned the prices may be taken as representative. On the above showing of £39 5s.--$196.25--per day the plant gives a gross return, in round figures, of £235--$1,175--for a six-day week, or £11,775--$58,875--for a 300-day year. Allowing £5,000--$25,000--a liberal figure--for the annual operation of the plant, the sum of £6,775--$33,875--remains--the net return from the realization of some of the utilitarian material recovered from the dust-bins into which 85,000 people throw what they consider to be useless during the course of the year. Truly may it be said that the average member of the public has but little, if any, idea of the wealth he allows to slip through his hands as a result of carelessness or lack of knowledge. Again, when it is reflected that, for the most part, the whole of such potential wealth as this has been permitted to vanish in smoke, or if incombustible to be kicked from pillar to post, we certainly cannot complain when accused of deplorable extravagance.
