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.
Everyone had worked at the construction of the mill, and on the 1st of December it was finished. As usual, Pencroft was delighted with his work, and had no doubt that the apparatus was perfect.
"Now for a good wind," said he, "and we shall grind our first harvest splendidly!"
"A good wind, certainly," answered the engineer, "but not too much, Pencroft."
"Pooh! our mill would only go the faster!"
"There is no need for it to go so very fast," replied Cyrus Harding. "It is known by experience that the greatest quantity of work is performed by a mill when the number of turns made by the sails in a minute is two-thirds the number of feet traversed by the wind in a second. A moderate breeze, which passes over twenty-four feet to the second, will give sixteen turns to the sails during a minute, and there is no need of more."
"Exactly!" cried Herbert; "a fine breeze is blowing from the northeast, which will soon do business for us."
There was no reason for delaying the inauguration of the mill, for the settlers were eager to taste the first piece of bread in Lincoln Island. Two or three bushels of wheat were ground, and the next day at breakfast a magnificent loaf, a little heavy perhaps, although raised with yeast, appeared on the table at Granite House. Everyone munched away at it with a pleasure easily understood.
In the meanwhile, the stranger had not reappeared. Several times Gideon Spilett and Herbert searched the forests in the neighborhood of Granite House, without meeting or finding any trace of him. They became seriously uneasy at this prolonged absence. Certainly, the
