Weeks and months rolled on.  Silva used to listen to what Mr Brand said to him, and he always behaved very well.  Indeed, we had ceased to remember that he had been a pirate, and had joined in the most atrocious murders; still, I do not know that he was a changed man--I am afraid not; that is to say, I am afraid had a piratical vessel come off the island, he would not have refused to join her.  One very hot day Jerry and I had accompanied him in an excursion along the shore, when suddenly he said that he should like to bathe.  We walked on a little further, leaving him to undress, and then we agreed that the water looked very tempting, and that we would bathe also.  We were by this time at some little distance from him.  We were partly undressed when we saw that the tide was rising, so we carried our things higher up the beach.
