American brotherhood redeveloped. Reciprocal arrangements were made among the gangs over constantly increasing areas. Trade developed to a certain extent, as between one gang and another. But the interchange of knowledge became more important than that of goods, as skill in the handling of synthetic processes developed. Within the gang, an economy was developed that was a compromise between individual liberty and a military socialism. The right of private property was limited practically to personal possessions, but private privileges were many, and sacredly regarded. Stimulation to achievement lay chiefly in the winning of various kinds of leadership and prerogatives, and only in a very limited degree in the hope of owning anything that might be classified as "wealth," and nothing that might be classified as "resources." Resources of every description, for military safety and efficiency, belonged as a matter of public interest to the community as a whole. In the meantime, through these many generations, the Hans had developed a luxury economy, and with it the perfection of gilded vice and degradation. The Americans were regarded as "wild men of the woods." And since they neither needed nor wanted the woods or the wild men, they treated them as beasts, and were conscious of no human brotherhood with them. As time went on, and synthetic processes of producing foods and materials were further developed, less and less ground was needed by the Hans for the purposes of agriculture, and finally, even the working of mines was abandoned when it became cheaper to build up metal from electronic vibrations than to dig them out of the ground. The Han race, devitalized by its vices and luxuries, with machinery and scientific processes to satisfy its every want, with virtually no necessity of labor, began to assume a defensive attitude toward the Americans. And quite naturally, the Americans regarded the Hans with a deep, grim hatred. Conscious of individual superiority as men, knowing that latterly they were outstripping the Hans in science and civilization, they longed desperately for the day when they should be powerful enough to rise and annihilate the Yellow Blight that lay over the continent. At the time of my awakening, the gangs were rather loosely organized, but were considering the establishment of a special military force, whose special business it would be to harry the Hans and bring down their air ships whenever possible without causing general alarm among the Mongolians. This force was destined to become the
