The last bed of rock, before we reached the cave which Jack had pierced, was so soft, and easy to work, that we had little difficulty in proportioning and opening the place for our door; I hoped that, being now exposed to the heat of the sun, it would soon become as hard as the original surface.

The door was that we had used for the staircase at Falcon's Nest; for as we only intended to make a temporary residence of our old tree, there was no necessity for solid fittings; and, besides, I intended to close the entrance of the tree by a door of bark, more effectually to conceal it, in case savages should visit us.

I then laid out the extent of the grotto at pleasure, for we had ample space.

We began by dividing it into two parts; that on the right of the entrance was to be our dwelling; on the left were, first, our kitchen, then the workshop and the stables; behind these were the store-rooms and the cellar.

In order to give light and air to our apartments, it was necessary to insert in the rock the windows we had brought from the ship; and this cost us many days of labour.
