desperation, we have even asked for the aid of the Ether-Eaters. Yes, we have in finality exercised our Will-Power to sweep back the rolling billows! In vain! What has been accomplished? The dust has retreated for a moment, has paused—and has welled onward. It has returned silently triumphant, and it has again hung its pall of blackness over a fear-haunted, nightmare-ridden Space."
Swelling in soundless sorrow through the Hall of the Mist rose the racing thoughts of the Great Brain. "Our chemists with a bitter doggedness never before displayed have devoted their time to the production of Super-Brains, in the hope of making one which could defeat the Cosmic Dust. They have changed the chemicals used in our genesis; they have experimented with molds and forms; they have tried every resource. With what result? There have come forth raging monstrosities, mad abominations, satanic horrors and ravenous foul things howling wildly the nameless and indescribable phantoms that thronged their minds. We have killed them in order to save ourselves. And the Dust has pushed onward! We have appealed to every living Brain to help us. We appealed, in the forgotten, dream-veiled centuries, for aid in any form. From time to time we have been offered plans, which for a while have made terrific inroads on the Dust, but plans which have always failed.
"The triumph of the Cosmic Dust has almost come. There is so little time left us that our efforts now must inevitably be futile. But today, in the hope that some Brain, either of the old ones or of the gigantic new ones, has discovered a possibility not yet tried, we have called this conference, the first in more than twelve thousand years."
The tense, alert silence of the hall relaxed and became soft when the thoughts of the Great Brain had stopped flowing. The electric waves which had filled the vast Hall of the Mist sank, and for a long time a strange tranquillity brooded there. But the mass was never still; the sea in front of the dais rippled and billowed from time to time as waves of thought passed through it. Yet no Brain offered to speak, and the seething expanse, as the minutes crept by, again became quiet.
In a thin column on the dais, rising high into the air, swayed the Great Brain; again and again it swept its glance around the hall, peering among the rolling, heaving shapes in the hope of finding somewhere in those thousands one which could offer a suggestion. But the minutes passed, and time lengthened, with no response; and the sadness of the fixed and changeless end crept across the last race. And the Brains, wrapped in their meditation, saw the Dust pushing at the glass shell of Antares with triumphant mockery.
The Great Brain had expected no reply, since for centuries it had been considered futile to combat the Dust; and so, when its expectation, though not its wish, was fulfilled, it relaxed and dropped, the signal that the meeting was over.
But the motion had scarcely been completed, when from deep within the center of the sea there came a violent heave; in a moment, a section collected itself and rushed together; like a waterspout it swished upward and went streaming toward the roof until it swayed thin and tenuous as a column of smoke, the top of the Brain peering down from the dimness of the upper hall.
"I have found an infallible plan! The Red Brain has conquered the Cosmic Dust!"
A terrific tenseness leaped upon the Brains, numbed by the cry that wavered in silence down the Hall of the Mist into the empty and dream-
