In the meanwhile, works of all sorts were continued, as well on Prospect Heights as at the corral, where Harding intended to build a farm. It is unnecessary to say that the seeds collected by Herbert on Tabor Island had been carefully sown. The plateau thus formed one immense kitchen-garden, well laid out and carefully tended, so that the arms of the settlers were never in want of work. There was always something to be done. As the esculents increased in number, it became necessary to enlarge the simple beds, which threatened to grow into regular fields and replace the meadows. But grass abounded in other parts of the island, and there was no fear of the onagers being obliged to go on short allowance. It was well worth while, besides, to turn Prospect Heights into a kitchen-garden, defended by its deep belt of creeks, and to remove them to the meadows, which had no need of protection against the depredations of quadrumana and quadrapeds. 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.
