“I’ll be glad enough to lay around our camp and rest for a day,” announced Sam.  “This task of exploring is not as easy as it looks.”

A little later they were in the boat and rowing back to where they had left the others, little dreaming of the strange events that had happened in their absence.

CHAPTER XVIII

UNEXPECTED VISITORS

It had been decided by the castaways to enlarge one of the rooms of the house, and as soon as the captain, Tom, and Sam had departed on their exploring tour, Dick and old Jerry set to work to cut down the posts necessary for the building.

While this was going on the three girls were by no means idle.  There were meals to get, dishes to wash, and it had been found that outdoor life was very rough on clothing, so there was a good bit of sewing and darning to be done.  Fortunately all of the girls were handy with a needle, so that a rent in a coat or a dress received immediate attention.

“Now you must make the alteration in the house very nice,” said Dora to Dick.  “Remember, we want a regular Queen Anne building, with round bay windows, and—­”

“And inlaid floors,” finished Dick, “not to mention steam heat, and—­”

“Mercy on us!” burst in Grace.  “Don’t mention steam heat in this climate.”

“Of course we want hot and cold water in the kitchen,” put in Nellie.  “What sort of a mansion would it be without hot and cold water,—­and a dumb waiter from the cellar, too,” and then all began to laugh.

“I know what I should like,” said Dora, after a pause.  “That would be a refrigerator.”

“If we had the ice,” finished Nellie.  “Dick, isn’t there any ice on board of the Golden Wave?”

“By Jove!  I think there is,” cried the oldest Rover boy.  “I never once thought of it before.”

“If there is, I wish you’d bring some the next time you go over.  We have lemons, and we could make delicious lemonade.”

“And we could make orange ice, too,” put in Grace.  “I know there was an ice-cream freezer on board of the ship.  It was in the cook’s galley.”

Old Jerry was coming to the house with a small tree he had cut down, and Dick sounded him about the ice.

“To be sure there was ice, several tons of it,” said Jerry.  “It was stowed away near the bow.  I don’t believe it’s all melted, either.”

“I’m going over to see,” cried Dick.  “We’ve got plenty of lemons and sugar; and lemonade, not to mention orange ice, would just strike the spot in this awfully hot weather.”

But as it was now noon, with the sun directly overhead, Dick decided to remain in the shade until four or five o’clock.  Dinner was had, and then the work of enlarging the house went on as before.

At half-past four Dick got out the rowboat and started for the wreck.  He had first thought to go alone, but old Jerry wanted to pick out certain tools needed for the house-building, as well as hunt for a keg of nails, and the two decided to go together, going and coming as quickly as possible.
