I was so excited by these heavy minute-guns following one another that I so far forgot my personal safety and my scalded hands as to clamber up into the hedge and stare towards Sunbury. As I did so a second report followed, and a big projectile hurtled overhead towards Hounslow. I expected at least to see smoke or fire, or some such evidence of its work. But all I saw was the deep blue sky above, with one solitary star, and the white mist spreading wide and low beneath. And there had been no crash, no answering explosion. The silence was restored; the minute lengthened to three.
Every moment I expected the fire of some hidden battery to spring upon him; but the evening calm was unbroken. The figure of the Martian grew smaller as he receded, and presently the mist and the gathering night had swallowed him up. By a common impulse we clambered higher. Towards Sunbury was a dark appearance, as though a conical hill had suddenly come into being there, hiding our view of the farther country; and then, remoter across the river, over Walton, we saw another such summit. These hill-like forms grew lower and broader even as we stared.
Now at the time we could not understand these things, but later I was to learn the meaning of these ominous kopjes that gathered in the twilight. Each of the Martians, standing in the great crescent I have described, had discharged, by means of the gunlike tube he carried, a huge canister over whatever hill, copse, cluster of houses, or other possible cover for guns, chanced to be in front of him. Some fired only one of these, some two--as in the case of the one we had seen; the one at Ripley is said to have discharged no fewer than five at that time. These canisters smashed on striking the ground--they did not explode--and incontinently disengaged an enormous volume of heavy, inky vapour, coiling and pouring upward in a huge and ebony cumulus cloud, a gaseous hill that sank and spread itself slowly over the surrounding country. And the touch of that vapour, the inhaling of its pungent wisps, was death to all that breathes.
