Private enterprise would also exercise another far-reaching beneficial influence. It would not lag behind the clock of progress. Science is ever advancing and the exploitation of waste lies in its true scientific utilization. Under the present conditions inventive effort in this province is not able to exercise the influence or reap the benefits which it really deserves. The tendency to be satisfied with what is already installed, no matter how inefficient it may be, is too deeply implanted. On the other hand, competition is the lever which impels private enterprise. To turn a blind eye to invention is to court disaster. Although we have made vast strides during the past few years in the processes of reclamation and utilization of waste we are still far from having penetrated the threshold of the new world of industry, science, and invention which it embraces. The unknown lies before us. For aught contemporary knowledge can say, other triumphs and vast fields of conquest, comparable with those associated with the gas and oil industries, are waiting to be discovered, and this fact is adequate to foster experiment, research, and investigation. We talk glibly of exploiting waste, but how many products entering intimately into our everyday life are being passed through the mill of reclamation? A little reflection will speedily exhaust the list. If we look around we can satisfy ourselves how much and what a variety of substances are still being permitted to run to utter loss. We have not yet found a use for spent matches, or a means of retipping those which have been scarcely lighted, despite the fact that this indispensable attribute to modern civilization has increased from 300 to 800 per cent. in price. How many typewriter ribbons are used by the tens of thousands of offices in the country during the year, and what is done with them when withdrawn from the machines as being unfit for further service? What is done with the stones and kernels from the millions of pounds of stone-fruits consumed during the year? The inventor is still confronted with the prize which will result from the discovery of an economic use for the 370,000,000 lb. of spent tea-leaves and 100,000,000 lb. of coffee-grounds left in our pots, cups, and urns during the twelve months. The lists of wastes awaiting profitable disposal are extremely lengthy. Some appear to be as impossible of successful solution as the discovery of the non-refillable bottle. But effort is not confined to the perfection of processes for the treatment of untouched wastes, because the real solution of this problem lies in the full scientific utilization of the product reclaimed. The fact that a waste is being exploited does not imply that such utilization is the most profitable. Investigation may indicate another and totally different, as well as more lucrative application for a certain material. So the inventor is not confined to a narrow field; his opportunities are illimitable.
