It was the summer vacation in the sea land. All the commencements in the mer colleges were just over. All the presidents of those institutions had made their speeches in languages dead and alive, and told all their classes what an enormous responsibility rested upon them, how they were bound to “go forward,” and “to conquer,” and to “build themselves up,” and to “develop themselves,” and be “leaders of their kind,” and, in short, do something in proportion to the expense bestowed on their education. This is a way they have in sea land. But naturally in the sea they take things cooler than we can on land, and you wouldn’t believe how very little difference the advent of all these expensively got up young mermen made in the water world if you had not been there to see. Now the old mer professor hadn’t had a very comfortable time. His class that year was rather a stupid one, and with all the pains he could take and all the “coaches” they could use they hadn’t passed a very good examination in magic. One young gentleman upon whom he had thought he could certainly depend being told to make himself invisible, which is a very difficult problem, had made a mistake, used the wrong formula, and by accident transformed the whole Board of Examiners, who were not expecting any such thing, into cuttle-fishes. There was dreadful confusion for a few minutes, for the student couldn’t remember how to turn them back again, and as the spell could not be undone by any one else, the members of the board got all tangled up together, while the professor, in an awful temper, was trying to teach the young man the right formula.
