Then he turned quite yellow; for the tide was up to his waist, and still the lobster held on. Then he thought over all the naughty things he ever had done; all the sand which he had put in the sugar, and the sloe-leaves in the tea, and the water in the treacle, and the salt in the tobacco (because his brother was a brewer, and a man must help his own kin). Then he turned quite blue; for the tide was up to his breast, and still the lobster held on. Then, I have no doubt, he repented fully of all the said naughty things which he had done, and promised to mend his life, as too many do when they think they have no life left to mend. Whereby, as they fancy, they make a very cheap bargain. But the old fairy with the birch rod soon undeceives them. And then he grew all colours at once, and turned up his eyes like a duck in thunder; for the water was up to his chin, and still the lobster held on. And then came a man-of-war's boat round the Mewstone, and saw his head sticking up out of the water. One said it was a keg of brandy, and another that it was a cocoa-nut, and another that it was a buoy loose, and another that it was a black diver, and wanted to fire at it, which would not have been pleasant for the mayor: but just then such a yell came out of a great hole in the middle of it that the midshipman in charge guessed what it was, and bade pull up to it as fast as they could. So somehow or other the Jack-tars got the lobster out, and set the mayor free, and put him ashore at the Barbican. He never went lobster-catching again; and we will hope he put no more salt in the tobacco, not even to sell his brother's beer. [Illustration: "A real live water-baby sitting on the white sand."--_P. 146_.] And that is the story of the Mayor of Plymouth, which has two advantages--first, that of being quite true; and second, that of having (as folks say all good stories ought to have) no moral whatsoever: no more, indeed, has any part of this book, because it is a fairy tale, you know. And now happened to Tom a most wonderful thing; for he had not left the lobster five minutes before he came upon a water-baby. A real live water-baby, sitting on the white sand, very busy about a little point of rock. And when it saw Tom it looked up for a moment, and then cried, "Why, you are not one of us. You are a new baby! Oh, how delightful!" And it ran to Tom, and Tom ran to it, and they hugged and kissed each other for ever so long, they did not know why. But they did not want any introductions there under the water. At last Tom said, "Oh, where have you been all this while? I have been looking for you so long, and I have been so lonely." "We have been here for days and days. There are hundreds of us about the rocks. How was it you did not see us, or hear us when we sing and romp every evening before we go home?" Tom looked at the baby again, and then he said:
