t of the
wall somewhere, and I can't feel the place. It's so puzzling being in
the dark. I don't know which is front and which is back now."

"Front's where the soft sand is," said Shock.

"Of course," I cried, feeling half stupefied all the time. "Then this
is the front here. I hung it on the stone and it was just above my
head."

I walked about on the soft sand, feeling about above my head, and all
over the face of the cave side for a long time in vain; and then with my
head swimming I sank down in despair, and leaned heavily back, to utter
a cry of pain.

"What's matter?" cried Shock, coming to me.

"I've struck the back of my head against a sharp stone," I cried,
turning round to feel for the projecting piece.

"Why, it's here, Shock. This is the piece I hung my jacket on, but it
has sunk down. No, no," I cried; "I forgot; it is the bottom of the
hole that has filled up. The sand has come up all this way. Keep
back."

I had turned on my hands and knees and was tearing out the sand just
below the projecting piece of sand-rock.

"What yer doing?" cried Shock. "You'll make more come down and cover us

"My jacket is buried down here," I cried, and I worked away feeling
certain that I should find it, and at last, in spite of the sand coming
down almost as fast as I tore it out, I scratched and scraped away till,
to my great delight, I got hold of a part of the jacket and dragged it
out.

"Hurrah!" I cried. "I've got it."

"And the bread and meat?" cried Shock. "Oh, give us a bit; I am so
bad."

"No," I said despairingly.

"What! yer won't give me a bit?" he cried fiercely.

"It isn't here," I said. "It was in my pocket, but it's gone. Stop!"
I cried; "it was a big packet and it must have come out."

I plunged my arms into the soft sand again, and worked away for long,
though I was ready to give up again and again, and my fingers were
getting painfully sore, but I worked on, and at last, to my great
delight, as I dug down something slipped slowly down on to the back of
my hands--I had dug down past it, and the sand had brought it out of the
side down to me.

"Here it is!" I cried, standing up and shaking the sand away from the
paper as I tore it open.

Shock uttered a cry like a hungry dog as he heard the paper rustle, and
then I divided the sandwiches in two parts and wrapped one back in the
paper.

"What yer doin'?" cried Shock.

"Saving half for next time," I said. "We m
