By fixing prices for all and every description of residue preservation and segregation at the source would be encouraged. The housewife, caretaker of the office, and manager of the factory would see that all waste was carefully husbanded, and that nothing possessing the slightest value would be thrown away. The dust-collectors could be encouraged to participate in the general round-up of waste by being given a commission upon all useful material brought in. It might be an over-riding commission to ensure complete and frequent collection. It is only necessary to apply sufficient stimulus in the form of hard cash to ensure that nothing is wasted. Private enterprise could carry out such a scheme whereas municipal authorities are precluded from following such a course. Under private auspices it would also become possible to exploit the waste accruing in our rural districts. Residences by the wayside, hamlets and country homes from their isolation have escaped the tentacles of previous recovery systems. No recognized specialist in residues, with the exception perhaps of the wardrobe dealer, ever passes their way to pay a call. But, with modern motor transport facilities it would be possible to call at these possible scattered sources of supply for anything and everything, and at regular intervals, so that the owners might be induced to preserve their useful materials. It is maintained that such collection would never prove profitable. Possibly not when considered upon its own footing, but when contemplated in a general scheme it would not only be lucrative, but contribute to the higher efficiency of the plant employed from being able to raise the working output to one more closely approaching the maximum capacity. Such a method of recovering the waste would stimulate competition which, in turn, would tend to the hardening of prices to the advantage of those who have waste for disposal. The plant would only need to study local conditions in so far as the disposal of readily decomposing refuse was concerned, such as that from householders, fish, meat and other organic matter. The municipal authorities, by virtue of their powers, would be able to ensure that this class of refuse was collected and treated promptly in the interests of the health of the community. Such waste as is not susceptible to deterioration could be sent or drawn from distant points, according to the advantage of price offered, as is actually the case to-day in regard to certain materials.
