Manipulated once more by my tyrant, I was stationed, like other reporters and radiomen, in a captive balloon. For the utmost in discomfort and lack of dignity let me recommend this ludicrous invention. Cramped, seasickened, inconvenienced--I don't like to mention this, but provisions for answering the calls of nature were, to say the least, inadequate--I swayed and rocked in that inconsiderable basket, chilled, blinded by the dazzle of the salt, knocked about by gusts of irresponsible wind, and generally disgusted by the uselessness of my pursuit. A telescope to the eye and constant radioreports from shuttling planes told of the approaching grass, but under the circumstances weariness rather than excitement or anxiety was the prevailing emotion. At last the collision came. The long runners, curiously flat from the air, pushed their way ahead. The salt seemed no more to them than bare ground, concrete, vegetation, or any of the hundred obstacles they had traveled. Unstutteringly the vinelike stolons went forward. A foot, two, six, ten. No recoil, no hesitation, no recognition they were traversing a wall erected against them. Behind these first outposts, the higher growth came on, and still farther off the great bulk itself reared skyward, blotting out the horizon behind, threatening, inexhaustible. It seemed to prod its precursors, to demand hungrily ever more and more room to expand. But the creeping of the runners over the first few feet of salt dwindled to a stop. This caused experienced observers like myself no elation; we had seen it happen many times before at the encountering of any novel obstacle, and its only effect had been to make the weed change its tactics in order to overcome the obstruction, as it did now. A second rank moved forward on top of the halted first, a third upon the second and so on till a living wall frowned down upon the salt, throwing its shadow across it for hundreds of ominous yards. It towered erect and then, repeating the tactic invariably successful, it toppled forward to create a bridgehead from which to launch new assaults. The next day new stolons emerged from the mass, but now for the first time excitement seized us up in our bobbing post of observation. Not only were the new runners visibly shorter in length but they crept forward more slowly, haltingly, as though hurt. This impression was generally discredited, people were surfeited with optimism; they felt our reports were wishful thinking. Their pessimism seemed to be confirmed when the weed repeated its action of the day before, falling ahead of itself upon the salt; and few took stock in our excited announcements that the grass had covered only half the previous distance. Again the probing fingers poked out, again the reserves piled up, again the mass fell. But it fell far short of a normal leap. There could no longer be any doubt about it; the advance had been slowed, almost stopped. The salt was working.
