To the British nation the magnitude and prosperity of this huge traffic in coal-tar derivatives with its enormous wealth is particularly galling. Had we displayed a more sympathetic attitude towards the discovery of Perkin and his endeavours, and had we displayed similar initiative, energy and enterprise the monopoly which became Germany’s might have been ours. But we disdained to exploit a waste. We left it to a persevering rival, and became content to pay him tribute for the utilization of a fundamental British discovery and incidentally to charge his coffers with the sinews of war. Had we kept the potential treasure-house of coal-tar to ourselves the history of the world might have been written very differently. It was the wealth accruing from the coal-tar dye-stuffs industry which enabled Germany to play a far bigger part than may be generally conceived in the development of her other industries, especially that pertaining to the chemical trade, the dye-works constituting the nursery where Germany raised her battalions of chemists. It must not be inferred from what I have narrated that the German has a peculiar prerogative in the mastery of waste products: far from it. In certain ranges of industry we have eclipsed the Teuton and have paddled our own canoe so far as blazing the trail of industrial economy is concerned. Nor is the Teuton temperamentally better adapted to the scientific exploitation of refuse. For the most part he has been compelled to investigate these divers potential raw materials to maintain his industrial existence. Moreover, as may be readily conceived from what I have related, the issue has been forced upon him by repressive official machinery and legislative measures. Discipline in this as in many other fields has fulfilled its purpose. Certainly it has reduced every German scrap-heap and dump into a Tom Tiddler’s ground and the application of its contents into a semi-automatic operation, or at least into part of the intricate routine of industry. It is to be hoped that we have not allowed the lesson thus taught to be lost. By now we should have learned, and digested thoroughly, the truth of the precept that waste creates wealth--and commercial power. CHAPTER III SALVAGE FROM THE ARMY SWILL-TUB Waste is one of the concomitant evils of a high civilization. Undoubtedly it is incidental to the primitive as well, but to a lesser degree. In this instance, however, the waste incurred does not represent a complete loss, because upon being discarded it decomposes, and thus continues the cycle of Nature.
