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 pepperpot, with a pointed roof, rose on the spot chosen. The four frames which formed the sails had been firmly fixed in the centre 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 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 six times 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 north-east, which will soon do our 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. On this morning 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. Every one munched away at it with a pleasure which may be easily understood.
