On the 15th of November, the third harvest was gathered in.How wonderfully had the field increased in extent, since eighteen months ago, when the first grain of wheat was sown! The second crop of six hundred thousand grains produced this time four thousand bushels, or five hundred millions of grains!
The colony was rich in corn, for ten bushels alone were sufficient for sowing every year to produce an ample crop for the food both of men and beasts.The harvest 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 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 northeast, 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.
