I never had a great deal of patience with theories of psychology--they seem to smack too much of the confessional and the catechism. But as I understand it, it is claimed that there exists what is called an unconscious--a reservoir of all sorts of thoughts lurking behind the conscious mind. The desires of this unconscious are powerful and tend to be expressed any time the conscious mind is offguard. Whether this metaphysical construction be valid or not, it seemed to me that some such thing had taken place while I was sick and my unconscious, or whatever it was, had outlined a very sensible project. There was no reason why I shouldnt write such a history as soon as I could take the time from my affairs. Certainly I had the talent for it and I believed it would give me some satisfaction. My pleasant speculations and plans for this literary venture were interrupted, as was my convalescence, by the loss of the Sahara depots. When I got the news, my principal concern wasnt for the incalculable damage to Consolidated Pemmican. My initial reaction was amazement at the ability of the devilgrass to make its way so rapidly across a sterile and waterless waste. In the years since its first appearance it had truly adapted itself to any climate, altitude, or condition confronting it. A few months before, the catastrophe would have plunged me into profound depression; now, with the resilience of recovery added to Miss Francis' assurance, it became merely another setback soon to be redeemed. From Senegal, near the middle of the great African bulge, to Tunis at the continent's northern edge, up through Sardinia and Corsica, the latest front of the Grass was arrayed. It occupied most of Italy and climbed the Alps to bite the eastern tip from Switzerland. It took Bavaria and the rest of Germany beyond the Weser. Only the Netherlands, Belgium, France, Spain and Portugal--a geographical purist might have added Luxembourg, Andorra and Monaco--remained untouched upon the Continent. Into this insignificant territory and the British Isles were packed all that was left of the world's two billion people: a blinded, starving mob, driven mad by terror. How many there were there, squirming, struggling, dying in a desperate unwillingness to give up existence, no matter how intolerable, no one could calculate; any more than a census could be taken of the numbers buried beneath the Grass now holding untroubled sway over ninetenths of the globe. Watchers were set upon the English coast in a manner reminiscent of 1940. I don't know exactly what value the giving of the alarm would have been; nevertheless, night and day eyes were strained through binoculars and telescopes for signs of the unique green on the horizon or the first seed slipping through to find a home on insular soil.
