I stared at him in a dazed way, rubbing the arm he had twisted for me. Nothing came to me to say, somehow.

 

“I lost consciousness for a moment or two,” I heard him say. “That’s what saved me. It made me stop thinking about them.”

 

“You nearly broke my arm in two,” I said, uttering my only connected thought at the moment. A numbness came over me.

 

“That’s what saved you!” he replied. “Between us, we’ve managed to set them off on a false tack somewhere. The humming has ceased. It’s gone -for the moment at any rate!”

 

A wave of hysterical laughter seized me again, and this time spread to my friend too — great healing gusts of shaking laughter that brought a tremendous sense of relief in their train. We made our way back to the fire and put the wood on so that it blazed at once. Then we saw that the tent had fallen over and lay in a tangled heap upon the ground.

 

We picked it up, and during the process tripped more than once and caught our feet in sand.

 

“It’s those sand-funnels,” exclaimed the Swede, when the tent was up again and the firelight lit up the ground for several yards about us.

“And look at the size of them!”

 

All round the tent and about the fireplace where we had seen the moving shadows there were deep funnel-shaped hollows in the sand, exactly similar to the ones we had already found over the island, only far bigger and deeper, beautifully formed, and wide enough in some instances to admit the whole of my foot and leg.

 

Neither of us said a word. We both knew that sleep was the safest thing we could do, and to bed we went accordingly without further delay, having first thrown sand on the fire and taken the provision sack and the paddle inside the tent with us. The canoe, too, we propped in such a way at the end of the tent that our feet touched it, and the least motion would disturb and wake us.

 

In case of emergency, too, we again went to bed in our clothes, ready for a sudden start.

 

It was my firm intention to lie awake all night and watch, but the exhaustion of nerves and body decreed otherwise, and sleep after a while came over me with a welcome blanket of oblivion. The fact that my companion also slept quickened its approach. At first he fidgeted and constantly sat up, asking me if I “heard this” or “heard that”. He tossed about on his cork mattress, and said the tent was moving and the river had risen over the point of the island, but each time I went out to look I returned with the report that all was well, and finally he grew calmer and lay still. Then at length his breathing became regular and I heard unmistakable sounds of snoring — the first and only time in my life when snoring has been a welcome and calming influence.

 

This, I remember, was the last thought in my mind before dozing off.

 

A difficulty in breathing woke me, and I found the blanket over my face.

But something else besides the blanket was pressing upon me, and my first thought was that my companion had rolled off his mattress on to my own in his sleep. I called to him and sat up, and at the same moment it came to me that the tent was surrounded. That sound of multitudinous soft pattering was again audible outside, filling the night with horror.

 

I called again to him, louder than before. He did not answer, but I missed the sound of his snoring, and also noticed that the flap of the tent was down. This was the unpardonable sin. I crawled out in the darkness to hook it back securely, and it was then for the first time I realised positively that the Swede was not here. He had gone.

 

I dashed out in a mad run, seized by a dreadful agitation, and the moment I was out I plunged into a sort of torrent of humming that surrounded me completely and came out of every quarter of the heavens at once. It was that same familiar humming — gone mad! A swarm of great invisible bees might have been about me in the air. The sound seemed to thicken the very atmosphere, and I felt that my lungs worked with difficulty.

 

But my friend was in danger, and I could not hesitate.

 

The dawn was just about to break, and a faint whitish light spread upwards over the clouds from a thin strip of clear horizon. No wind stirred. I could just make out the bushes and river beyond, and the pale sandy patches. In my excitement I ran frantically to and fro about the island, calling him by name, shouting at the top of my voice the first words that came into my head. But the willows smothered my voice, and the humming muffled it, so that the sound only travelled a few feet round me. I plunged among the bushes, tripping headlong, tumbling over roots, and scraping my face as I tore this way and that among the preventing branches.

 

Then, quite unexpectedly, I came out upon the island’s point and saw a dark figure outlined between the water and the sky. It was the Swede.

And already he had one foot in the river! A moment more and he would have taken the plunge.

 

I threw myself upon him, flinging my arms about his waist and dragging him shorewards with all my strength.
