So much for affairs in the Great City. I recognized during these days the possibility of an armed invasion from the Twilight Country. I was better prepared to meet it now, should it come, and I at once took steps to be warned as far in advance as possible. To this end I had girls patrolling the Narrow Sea, not only on our shore, but over in the Twilight Country as well; and I was satisfied that if Tao made any move we would be notified at once. Simultaneously with all this, we devoted ourselves to the unification of the nation, for in very truth it seemed about to disintegrate. Here it was that the girls were of the greatest assistance.
We organized them into an army which consisted of fifty squads of ten girls each, with a leader for each squad. All of these girls were armed with the light‑ray cylinders. With this "flying army" Mercer and I made a tour of the Light Country cities. We wasted no time with formalities, but rounded up Tao's men wherever we could find them, and transported them unceremoniously back to the Twilight Country shore.
In two or three of the cities—the Water City particularly—there was a show of rebellion among the people; but our light‑rays cowed them instantly, and in no instance did we have to kill or injure any one. Through Miela I made speeches everywhere. It was not my wish to hold the country in sullen subjection, and to that end I appealed to their patriotism in this coming war against Tao and the Twilight People. This aspect of the matter met with ready response, and everywhere our meetings ended in enthusiastic acclaim.
We started now to raise an army of young men, which we proposed to transport across the Narrow Sea for land operations in the Twilight Country. Before a week had passed I saw, by the response that came from my various proclamations, that conscription would be unnecessary. With this tangible evidence of the coming war the patriotism of the people grew by leaps and bounds. The fact that the girls of the Great City were not only in favor of it, but were actually already in service—a thing unprecedented in the history of the nation—brought the sympathies of all the women with us strongly.
Through the governors of each city I raised a separate army of young men, officered by the older men, most of whom had taken part in past fighting. Each of these little armies, as yet without arms, was drilled and held in readiness for orders from the Great City.
I had, during all this time, selected as many able men as possible from among the Great City's population, and given them over to Fuero and his associates for training in the use of the light‑ray rockets, the larger projectors, protective measures against the ray, and many other appliances which I understood only vaguely myself.
It was after our return from the tour of the different cities, and before the recruiting of the young men was fairly under way, when like a bombshell came the news from our flying patrol that a fleet of armed boats was coming down the river from the Lone City. The attack from Tao was at hand, and our preparations were still far from complete. We had our army of girls in active operation, and that was all. Tao's boats would reach the Light Country shore in a few hours. There was no time for anything but the hastiest of preparations. We decided then to call the army of girls and meet the boats in the Narrow Sea, turning them back if possible.
I have now to explain the method of defense against the light‑ray. In theory I only vaguely understood it. In practice it was simple and, like most defenses, only partially effective.
Bob Trevor, has already mentioned it—the suits of black cloth he saw in the Mercutian camp in Wyoming. It was not, as he had afterward supposed, a dye for fabrics. Instead, it was the thread of a worm—like our silk worm—which in its natural state was black and was impervious to the ray. By that I mean a substance whose molecules increased their vibration rate only slightly from a brief contact with the ray.
It was only partly efficacious, for after an exposure of a minute or more the intense heat of the ray was communicated. It then became partly penetrable, and anything close behind it would be destroyed.
