And now, all at once, the yard came in my head.  What had carried me through the roost would surely serve me to cross this little quiet creek in safety.  With that I set off, undaunted, across the top of the isle, to fetch and carry it back.  It was a weary tramp in all ways, and if hope had not buoyed me up, I must have cast myself down and given up.  Whether with the sea salt, or because I was growing fevered, I was distressed with thirst, and had to stop, as I went, and drink the peaty water out of the hags.

I came to the bay at last, more dead than alive; and at the first glance, I thought the yard was something farther out than when I left it.  In I went, for the third time, into the sea.  The sand was smooth and firm, and shelved gradually down, so that I could wade out till the water was almost to my neck and the little waves splashed into my face.  But at that depth my feet began to leave me, and I durst venture in no farther.  As for the yard, I saw it bobbing very quietly some twenty feet beyond.

I had borne up well until this last disappointment; but at that I came ashore, and flung myself down upon the sands and wept.

The time I spent upon the island is still so horrible a thought to me, that I must pass it lightly over.  In all the books I have read of people cast away, they had either their pockets full of tools, or a chest of things would be thrown upon the beach along with them, as if on purpose.  My case was very different.  I had nothing in my pockets but money and Alan’s silver button; and being inland bred, I was as much short of knowledge as of means.

I knew indeed that shell-fish were counted good to eat; and among the rocks of the isle I found a great plenty of limpets, which at first I could scarcely strike from their places, not knowing quickness to be needful.  There were, besides, some of the little shells that we call buckies; I think periwinkle is the English name.  Of these two I made my whole diet, devouring them cold and raw as I found them; and so hungry was I, that at first they seemed to me delicious.

Perhaps they were out of season, or perhaps there was something wrong in the sea about my island.  But at least I had no sooner eaten my first meal than I was seized with giddiness and retching, and lay for a long time no better than dead.  A second trial of the same food (indeed I had no other) did better with me, and revived my strength.  But as long as I was on the island, I never knew what to expect when I had eaten; sometimes all was well, and sometimes I was thrown into a miserable sickness; nor could I ever distinguish what particular fish it was that hurt me.

All day it streamed rain; the island ran like a sop, there was no dry spot to be found; and when I lay down that night, between two boulders that made a kind of roof, my feet were in a bog.
