The next day, the 22nd of May, the arrangement of their new dwelling was commenced.

In fact, the settlers longed to exchange the insufficient shelter of the Chimneys for this large and healthy retreat, in the midst of solid rock, and sheltered from the water both of the sea and sky.
Their former dwelling was not, however, to be entirely abandoned, for the engineer intended to make a manufactory of it for important works.
Cyrus Harding's first care was to find out the position of the front of Granite House from the outside.

He went to the beach, and as the pickaxe when it escaped from the hands of the reporter must have fallen perpendicularly to the foot of the cliff, the finding it would be sufficient to show the place where the hole had been pierced in the granite.
The pickaxe was easily found, and the hole could be seen in a perpendicular line above the spot where it was stuck in the sand.

Some rock pigeons were already flying in and out of the narrow opening; they evidently thought that Granite House had been discovered on purpose for them.

It was the engineer's intention to divide the right portion of the cavern into several rooms, preceded by an entrance passage, and to light it by means of five windows and a door, pierced in the front.
