 At Putney, as I afterwards saw, the bridge was almost lost in a tangle of this weed, and at Richmond, too, the Thames water poured in a broad and shallow stream across the meadows of Hampton and Twickenham. As the waters spread the weed followed them, until the ruined villas of the Thames Valley were for a time lost in this red swamp, whose margin I explored, and much of the desolation the Martians had caused was concealed.

In the end the red weed succumbed almost as quickly as it had spread. A cankering disease, due, it is believed, to the action of certain bacteria, presently seized upon it. Now by the action of natural selection, all terrestrial plants have acquired a resisting power against bacterial diseases—they never succumb without a severe struggle, but the red weed rotted like a thing already dead. The fronds became bleached, and then shrivelled and brittle. They broke off at the least touch, and the waters that had stimulated their early growth carried their last vestiges out to sea.

My first act on coming to this water was, of course, to slake my thirst. I drank a great deal of it, and, moved by an impulse, gnawed some fronds of red weed; but they were watery, and had a sickly, metallic taste. I found the water was sufficiently shallow for me to wade securely, although the red weed impeded my feet a little; but the flood evidently got deeper towards the river, and I turned back to Mortlake. I managed to make out the road by means of occasional ruins of its villas and fences and lamps, and so presently I got out of this spate and made my
