“Young gentleman,” exclaimed the doctor, bristling up, “you might sail under a less honoured flag, and fight under it too, let me tell you! It is one which has made itself respected in every sea, and will ever be found on the side of freedom and justice.”

“I beg your pardon, doctor,” answered Desmond. “If I was not an English midshipman, I should be perfectly ready to become an American commodore, and I fully believe your navy, for its size, is superior to that of any other nation under the sun.”

“Well, well, my young friend, we all of us have our national prejudices, and it is right that we should, provided we do not bring them too prominently forward. You may think England the tallest country in the world, and I may consider the United States taller still, but it is as well not to be measuring heights, or we may both have to come down a peg or two.”

“Come,” said Tom, “let us set up the flag-staff and hoist the stars and stripes, and should one of Uncle Sam’s ships come by, we will hand over the island as a free gift in exchange for our passage to any part of the world for which she may be bound.”

It did not take long to form a flag-staff and to fit it with rigging: the chief difficulty was to dig a hole of sufficient depth in the coral rock in which to step it. This, however, was at last done, and the wind having fallen, before the evening the flag-staff was fixed, and with a hearty cheer, led by the doctor, the stars and stripes were run up to the top. The flag was, however, hauled down again at sunset. Tom also had a quantity of wood collected and piled up on the highest point near the flag-staff, so that should a ship at any time in the evening be seen in the offing, it might be lit to attract attention. One of the brass guns which had beer brought on shore was placed on its carriage near the flag-staff, so that it might be fired if necessary.

“We have had a good day’s work, and I propose that to-morrow we lay down the keel of our vessel,” said Desmond.

To this Tom readily agreed; and the two midshipmen, with the doctor, sat up until a late hour, discussing the subject and drawing plans for their proposed craft. They had a couple of adzes, three axes, and two augers, but only five of the party could be engaged on the building; indeed, it would have been dangerous to have entrusted some of them with such tools. Billy to a certainty would have cut off his toes, and neither Tom nor Desmond were accustomed to their use, although they knew what it was necessary to do. To form the keel was simple work enough, to shape the timbers properly required the greatest skill.

Here the doctor was superior to the rest. He chose a level part of the sand, on which he drew the form of the timbers, and the rest of the party executed the plans he gave them. As the timbers had to be out in two, a saw-pit was dug, at which Billy was doomed to work as under-sawyer, a task which Desmond assured him he performed to perfection. By the end of the first day the keel was put down and the stem and stern-post set up.

“I have other work, which must not be neglected, my friends,” said the doctor, when the party were collected at supper. “We must look after fresh provisions. Perhaps, Rogers, you or Desmond will take your guns and shoot some birds to-morrow; there are large numbers, I see, at the further end of the island. They may prove wholesome, if not palatable food. I don’t know who are the best fishermen among you, but I would advise that two should go out every day in the boat fishing, so that we may not trespass on our salt provisions.”

“Pat Casey is the most skilful fisherman among us, and he with another of our party will do as you suggest, doctor,” said Tom.
