I hesitated as to whether I should go farther in that direction, which was to the opposite side from where I had left the boat; but there was a sort of peninsula jutting out from the main part of the reef; and near the end of this I saw what I fancied to be a collection of rare shells, and I was now desirous of possessing some. With this view, then, I kept on.

I had already observed several sorts of shells among the sand that lay between the boulders, some with fish in them, and others opened and bleached. None of these kinds were new to me, for I had seen them all many a time before—even in the potato-field, where they turned up among the wreck. They were only blue mussels, and a sort the farm people called “razors,” and “whelks,” and common “cockle-shells.” I saw no oysters, and I regretted this, for I had grown hungry and could have eaten a dozen or two; but it was not the ground for these. Plenty of little crabs and lobsters there were, but these I did not fancy to eat unless I could have boiled them, and that of course was not possible under the circumstances.

On my way to the front of the peninsula, I looked for “sea-urchin,” but none fell in my way. I had often wished to get a good specimen of this curious shell, but without success. Some of them turned up now and then upon the beach near our village, but they were not allowed to lie long. As they made a pretty ornament for the mantel-shelf, and were rare upon our coast, it was natural they should be prized above the common kinds, and such was in reality the case. This reef being remote, and being seldom visited by any of the boatmen, I was in hopes I should find some upon it, and I was determined to look narrowly for one. With this view I sauntered slowly along, examining every crevice among the rocks, and every water hole that lay within eyeshot of my path.

I had great hopes that I should find something rare upon the peninsula. The glittering forms that had first induced me to turn my steps in that direction, seemed to gleam still brighter as I drew near. For all that, I did not particularly hasten. I had no fear that the shells would walk off into the water. These were houses whose tenants had long since deserted them,

and I knew they would keep their place till I got up; so, under this impression, I continued to go deliberately, searching as I went. I found nothing to my mind until I had reached the peninsula; but then indeed a beautiful object came under my eyes. It was of a dark red colour, round as an orange, and far bigger; but I need not describe what I saw, since every one of you must have seen and admired the shell of the sea-urchin.

It was not long before I held it in my hand, and admiring its fine curving outlines, and the curious protuberances that covered them. It was one of the handsomest I had ever seen, and I congratulated myself upon the pretty souvenir it would make of my trip.

For some minutes I kept looking at it, turning it over and over, and peeping into its empty inside—into the smooth white chamber that its tenant had long since evacuated. Yes, some minutes passed before I tired of this manipulation; but at length I remembered the other shells I had noticed, and strode forward to gather them.

Sure enough they were strangers, and fair strangers too. They were of three or four sorts, all new to me; and on this account I filled my pockets with them, and after that both my hands, and then turned round with the intention of going back to the boat.

Gracious heaven! what did I see? A sight that caused me to drop my shells, sea-urchin and all, as if they had been pieces of red-hot iron. I dropped them at my feet, and was nigh to falling on top of them, so greatly was I astonished at what I saw. What was it? My boat! my boat! Where was my boat?
