That day the cross-beams of the floor were laid and securely fastened at the corners. Then the other logs were sawed and notched for the corner-posts. It was impossible to split the timber for rafters, so the Captain advised the use of smaller tree-trunks for this purpose.

“What shall we do to keep out the rain or wild animals?” asked Ruth, seeing that no windows had been provided for the old hut.

“We can hang up water-proof canvas in the windows if it rains, but I have an idea for a door that I want to work on to-morrow,” replied the Captain.

The carpentry now went steadily on, and without friction, as each one was anxious to see a finished hut. They were tremendously interested in their work, too, and that always makes a task easy.

Mrs. Vernon superintended everything, and demonstrated a wonderful knowledge of woodcraft. Then, whenever the carpenters were cheerfully working without her help, she turned to her own plans. These had occasioned curious comment from the four girls, because they could not see what could be built with a lot of short boards which had been taken from the boxes.

“You’ll see when I’m through,” replied the Captain to all their questions.

The scouts worked so industriously that the new side walls were completed, and they were eager to begin work on the roof. The hut was much longer than the old one, but its width was the same, as it used the end wall of the old hut for one side of its own.

The meeting of the two front walls of the huts, however, had been a problem. The scouts could not figure out how to nail any boards or logs to a corner post already used for that purpose. But Julie thought out a scheme.

“We’ll leave that meeting place in front, for the door. Then we’ll use a post for the other side of our door, and begin there with the wall.”

This was hailed as a fine idea, so they tried it. But the door-lintel was not as secure as it might be, and the girls dodged in and out to avoid having it come down upon their heads should it topple. They had no doubt but that it would fall in sooner or later.
