Of all the incidents in that afternoon, I think the sight of these placards brought home to me most forcibly two of the salient characteristics of Nordenholt’s many-sided mind: his foresight and his self-reliance. Their appearance in the streets at that moment showed that they formed part of a plan which had been decided upon several days in advance, since time had to be allowed for printing and distributing them; whilst the fact that they were being posted up within two hours of the close of the meeting proved that Nordenholt had never had the slightest doubt of his success in dominating the Ministers. Later on, I became familiar with these posters. They were not identical by any means; and I learned to expect a difference in their wording according to the district in which they were posted up. The methods of varied personal appeal had long been familiar to the advertising world; but I found that Nordenholt had broken away from tradition and had staked everything upon his knowledge of the human mind. In these advertisements his psychological instinct was developed in an uncanny degree which was clear enough to me, who knew the secret; but I doubt if any man without my knowledge would have seen through the superficial aspect of them quite so readily. In this first stage of his campaign he had to conceal his hand. The advertisements were merely the first great net which he spread in order to capture every man who would be at all likely to be useful to him, while the meshes had to be left wide enough to allow the undesirable types to slip through. The proclamations--for they really took this form--set forth concisely the exact danger which threatened the food-supply of the country; explained why it was essential that immense masses of nitrogenous material must be manufactured; and called for the immediate enrolment of volunteers from selected trades and professions. As a primary inducement, the scale of remuneration offered was far above the normal pay in any given line. It was, in fact, so high that I fell at once to calculating the approximate total of wages which would be payable weekly; and the figures took me by surprise when I worked them out. No single private fortune, however gigantic, could have kept the machinery running for even a few months at the uttermost. When I pointed this out to Nordenholt he seemed amused and rather taken aback; but his surprise was at my obtuseness and not at my calculations.
