was completed, and the last fortnight of the month
of November was devoted to the work of converting it into food for man.
In fact, they had corn, but not flour, and the establishment of a mill
was necessary. Cyrus Harding could have utilized the second fall which
flowed into the Mercy to establish his motive power, the first
being already occupied with moving the felting mill, but, after some
consultation, it was decided that a simple windmill should be built on
Prospect Heights. The building of this presented no more difficulty than
the building of the former, and it was moreover certain that there would
be no want of wind on the plateau, exposed as it was to the sea breezes.

"Not to mention," said Pencroft, "that the windmill will be more lively
and will have a good effect in the landscape!"

They set to work by choosing timber for the frame and machinery of the
mill. Some large stones, found at the north of the lake, could be easily
transformed into millstones, and as to the sails, the inexhaustible case
of the balloon furnished the necessary material.

Cyrus Harding made his model, and the site of the mill was chosen a
little to the right of the poultry-yard, near the shore of the lake. The
frame was to rest on a pivot supported with strong timbers, so that it
could turn with all the machinery it contained according as the wind
required it. The work advanced rapidly. Neb and Pencroft had become
very skilful carpenters, and had nothing to do but to copy the models
provided by the engineer.

Soon a sort of cylindrical box, in shape like a pepper-pot, with a
pointed roof, rose on the spot chosen. The four frames which formed the
sails had been firmly fixed in the center beam, so as to form a certain
angle with it, and secured with iron clamps. As to the different
parts of the internal mechanism, the box destined to contain the two
millstones, the fixed stone and the moving stone, the hopper, a sort of
large square trough, wide at the top, narrow at the bottom, which would
allow the grain to fall on the stones, the oscillating spout intended to
regulate the passing of the grain, and lastly the bolting machine, which
by the operation of sifting, separates the bran from the flour,
were made without difficulty. The tools were good, and the work not
difficult, for in reality, the machinery of a mill is very simple. This
was only a question of time.

Every one had worked at the construction of the mill, and on the 1st
