From this vantage point I surveyed the crater again.  Far away at the top of the enormous shadow I cast was the little white handkerchief fluttering on the bushes.  It was very little and very far, and Cavor was not in sight.  It seemed to me that by this time he ought to be looking for me.  That was the agreement.  But he was nowhere to be seen.

I stood waiting and watching, hands shading my eyes, expecting every moment to distinguish him.  Very probably I stood there for quite a long time.  I tried to shout, and was reminded of the thinness of the air.  I made an undecided step back towards the sphere.  But a lurking dread of the Selenites made me hesitate to signal my whereabouts by hoisting one of our sleeping-blankets on to the adjacent scrub.  I searched the crater again.

It had an effect of emptiness that chilled me.  And it was still.  Any sound from the Selenites in the world beneath had died away.  It was as still as death.  Save for the faint stir of the shrub about me in the little breeze that was rising, there was no sound nor shadow of a sound.  And the breeze blew chill.

Confound Cavor!

I took a deep breath.  I put my hands to the sides of my mouth.  “Cavor!” I bawled, and the sound was like some manikin shouting far away.

I looked at the handkerchief, I looked behind me at the broadening shadow of the westward cliff I looked under my hand at the sun.  It seemed to me that almost visibly it was creeping down the sky.  I felt I must act instantly if I was to save Cavor.  I whipped off my vest and flung it as a mark on the sere bayonets of the shrubs behind me, and then set off in a straight line towards the handkerchief.  Perhaps it was a couple of miles away—­a matter of a few hundred leaps and strides.  I have already told how one seemed to hang through those lunar leaps.  In each suspense I sought Cavor, and marvelled why he should be hidden.  In each leap I could feel the sun setting behind me.  Each time I touched the ground I was tempted to go back.

A last leap and I was in the depression below our handkerchief, a stride, and I stood on our former vantage point within arms’ reach of it.  I stood up straight and scanned the world about me, between its lengthening bars of shadow.  Far away, down a long declivity, was the opening of the tunnel up which we had fled, and my shadow reached towards it, stretched towards it, and touched it, like a finger of the night.

Not a sign of Cavor, not a sound in all the stillness, only the stir and waving of the scrub and of the shadows increased.  And suddenly and violently I shivered.  “Cav—­” I began, and realised once more the uselessness of the human voice in that thin air.  Silence.  The silence of death.

Then it was my eye caught something—­a little thing lying, perhaps fifty yards away down the slope, amidst a litter of bent and broken branches.  What was it?  I knew, and yet for some reason I would not know.  I went nearer to it.  It was the little cricket-cap Cavor had worn.  I did not touch it, I stood looking at it.
