I could never stay long enough on the shore. The tang of the untainted, fresh and free sea air was like a cool, quieting thought, and the shells and pebbles and the seaweed with tiny living creatures attached to it never lost their fascination for me. One day Miss Sullivan attracted my attention to a strange object which she had captured basking in the shallow water. It was a great horseshoe crab—the first one I had ever seen. I felt of him and thought it very strange that he should carry his house on his back. It suddenly occurred to me that he might make a delightful pet; so I seized him by the tail with both hands and carried him home. This feat pleased me highly, as his body was very heavy, and it took all my strength to drag him half a mile. I would not leave Miss Sullivan in peace until she had put the crab in a trough near the well where I was confident he would be secure. But next morning I went to the trough, and lo, he had disappeared! Nobody knew where he had gone, or how he had escaped. My disappointment was bitter at the time; but little by little I came to realize that it was not kind or wise to force this poor dumb creature out of his element, and after awhile I felt happy in the thought that perhaps he had returned to the sea.
