sailor's reasoning was very just, and pointed out an incomprehensible fact, for the document appeared to have been recently written, when the colonists found it in the bottle. Moreover, it gave the latitude and longitude of Tabor Island correctly, which implied that its author had a more complete knowledge of hydrography than could be expected of a common sailor.
"There is in this, again, something unaccountable," said the engineer; "but we will not urge our companion to speak. When he likes, my friends, then we shall be ready to hear him!"
During the following days the stranger did not speak a word, and did not once leave the precincts of the plateau. He worked away, without losing a moment, without taking a minute's rest, but always in a retired place. At meal times he never came to Granite House, although invited several times to do so, but contented himself with eating a few raw vegetables. At nightfall he did not return to the room assigned to him, but remained under some clump of trees, or when the weather was bad crouched in some cleft of the rocks. Thus he lived in the same manner as when he had no other shelter than the forests of Tabor Island, and as all persuasion to induce him to improve his life was in vain, the colonists waited patiently. And the time was near, when, as it seemed, almost involuntarily urged by his conscience, a terrible confession escaped him.
On the 10th of November, about eight o'clock in the evening, as night was coming on, the stranger appeared unexpectedly before the settlers, who were assembled under the verandah. His eyes burned strangely, and he had quite resumed the wild aspect of his worst days.
Cyrus Harding and his companions were astounded on seeing that, overcome by some terrible emotion, his teeth chattered like those of a person in a fever. What was the matter with him? Was the sight of his fellow-creatures insupportable to him? Was he weary of this return to a civilised mode of existence? Was he pining for his former savage life? It appeared so, as soon he was heard to express himself in these incoherent sentences:—
"Why am I here?... By what right have you dragged me from my islet?... Do you think there could be any tie between you and me?... Do you know who I am—what I have done—why I was there—alone? And who told you that I was not abandoned there—that I was not condemned to die there?... Do you know my past?... How do you know that I have not stolen, murdered—that I am not a wretch—an accursed being—only fit to live like a wild beast far from all—speak—do you know it?"
The colonists listened without interrupting the miserable creature, from whom these broken confessions escaped, as it were, in spite of himself. Harding wishing to calm him, approached him, but he hastily drew back.
"No! no!" he exclaimed; "one word only—am I free?"
"You are free," answered the engineer.
"Farewell then!" he cried, and fled like a madman.
Neb, Pencroft, and Herbert ran also towards the edge of the wood—but they returned alone.
"We must let him alone!" said Cyrus Harding.
"He will never come back!" exclaimed Pencroft.
"He will come back," replied the engineer.
Many days passed; but Harding—was it a sort of presentiment?—persisted in the fixed idea that sooner or later the unhappy man would return.
"It is the last revolt of his wild nature," said he, "which remorse has touched, and which renewed solitude will terrify."
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 onagas 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 quadrupeds.
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 utilised 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 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
