As Mark cut them down, some ash, some willow, and a few alder, Bevis stripped off the twigs with a billhook, and shortened them to the proper length. All the poles were ready in one morning, and in the afternoon coming again they set up the two stout corner posts. Next day the rafters were fitted, they had to bring a short ladder to get at the cliff over the mouth of the cave. Then the hurdles were brought and set up, and the brushwood cut and thrown on the top.
Sedges grew in quantities at the other end of the island, where the ground sloped till it became level with the water. In cutting them they took care to leave an outer fringe standing, so that if any one passed, or by any chance looked that way from the shore, he should not see that the sedges had been reaped. They covered the roof two feet thick with brushwood, sedges, and reed-grass, which they considered enough to keep out any ordinary shower.
Of course if the tornadoes common to these tropical countries should come they must creep into the inner cave. Against such fearful storms no thatch they could put up would protect them. The walls took a whole day to finish, as it required such a quantity of brushwood, and it had to be fastened in its place with rods, thrust into the ground, and tied at the top to the outside rafters.
At last the hut was finished, and they could stand up, or walk about in it; but when the carpet-curtain was dropped, it was dark, for they had forgotten to make a window. But in the daytime they would not want one, as the curtain could be thrown aside, and the doorway would let in plenty of light, as it faced the south. At night they would have a lantern hung from the roof.
"It's splendid," said Mark; "we could live here for years."
"Till we forgot what day it was, and whether it was Monday or Saturday," said Bevis.
"And our beards grow down to our waists." Their chins were as smooth as possible.
"Ships would be sent out to search for us."
"And when we come home everybody would come to see us," said Mark. "Just think of all the wonders we shall have to tell them!"
"I wish Ted could see it," said Bevis, "and Charlie, and Val."
"Wouldn't they be jealous if they knew," said Mark. "They'd kill us if we did not let them come too."
