mandibles and the effect of their poisonous formic acid became intolerable. Did I dare remove my mask while the air about me was foul with the gas discharged from the weapons of my allies? While I felt the attacks elsewhere upon my body gradually diminishing as the insects succumbed to the deadly fumes, the two upon my face waxed more vicious under the protection of my mask. One at each eye, they were trying to blind me. The pain was unbearable. Better the suffocating deathgas than the torture of lacerated eyes! Frantically I removed the headgear and tore at the shiny black fiends. Strange to tell, I discovered that I could breathe near the vicinity of the great oxygen tanks, where enough oxygen lingered to support life at least temporarily. The two vicious insects, no longer protected by my gas-mask, scurried from me like rats from a sinking ship and disappeared behind the oxygen tanks.
This attack of our enemies, though unsuccessful on their part, was dire in its significance, for it had shown more cunning and ingenuity than anything that had ever preceded it. Heretofore, their onslaughts had been confined to direct attacks upon us personally or upon the synthetic-food laboratories, but in this last raid they had shown an amazing cleverness that portended future disaster, unless they were checked at once. It was obvious they had ingeniously planned to smother us by the suspension of work at the oxygen plant, knowing that they themselves could exist in an atmosphere containing a greater percentage of carbondioxide. Their scheme, then, was to raid our laboratories for food.

A Continuation of Delfair's Account
Although it was evident that the cessation of all plant-life spelled inevitable doom for the insect inhabitants of Earth, their extermination did not follow as rapidly as one might have supposed. There were years of internecine warfare. The insects continued to thrive, though in decreasing numbers, upon stolen laboratory foods, bodies of human beings and finally upon each other; at first capturing enemy species and at last even resorting to cannibalistic procedure. Their rapacity grew in inverse proportion to their waning numbers, until the meeting of even an isolated insect might mean death, unless one were equipped with poison gas and prepared to use it upon a second's notice.
I am an old man now, though I have not yet lived quite two centuries,
