The Mysterious Island Jules Verne (red white royal blue txt) 📖

and the coast were transversely cut by a watercourse which the colonists had to cross when ever they wished to reach the northern part of the island. To avoid this they had to make a considerable detour, and to walk westward as far as the sources of Red Creek. Their best plan therefore was to build two causeways, one on the plateau and one on the shore, twenty to twenty-five feet long, simply constructed of trees squared by the axe. This was the work of some days. When these bridges had been built, Neb and Pencroff profited by them to go to the oyster-bed which had been discovered off the down. They dragged after them a sort of rough cart which had taken the place of the inconvenient hurdle; and they brought back several thousand oysters, which, were readily acclimated among the rocks, and formed a natural preserve at the mouth of the Mercy. They were excellent of their kind, and formed an almost daily article of diet. In fact, Lincoln Island, though the colonists had explored but a small portion of it, already supplied nearly all their wants, while it seemed likely that a minute exploration of the western forests would reveal a world of new treasures.

Only one privation still distressed the colonists. Azotic food they had in plenty, and the vegetables which corrected it; from the ligneous roots of the dragon-trees, submitted to fermentation, they obtained a sort of acidulated beer. They had even made sugar, without sugarcane or beetroot, by collecting the juice which distills from the Acer saccharinum, a sort of maple which flourishes in all parts of the temperate zone, and which abounded on the island. They made a very pleasant tea from the plant brought from the warren; and, finally, they had plenty of salt, the only mineral component necessary to food⁠—but bread was still to seek.

Perhaps, at some future time, they would have been able to replace this aliment by some equivalent, sago flour, or the breadfruit tree, which they might possibly have discovered in the woods of the southwest; but so far they had not met with them. Just at this time a little incident occurred which brought about what Smith, with all his ingenuity, could not have achieved.

One rainy day the colonists were together in the large hall of Granite House, when Herbert suddenly cried,

“See, Mr. Smith, a grain of corn.”

And he showed his companions a single gram which had got into the lining of his waistcoat through a hole in his pocket. Pencroff had given him some ringdoves in Richmond, and in feeding them one of the grains had remained in his pocket.

“A grain of corn?” said the engineer, quickly.

“Yes, sir; but only one.”

“That’s a wonderful help,” said Pencroff, laughing. “The bread that grain will make will never choke us.”

Herbert was about to throw away the grain, when Cyrus Smith took it, examined it, found that it was in good condition, and said quietly to the sailor:⁠—

“Pencroff, do you know how many ears of corn will spring from one grain?”

“One, I suppose,” said the sailor, surprised at the question.

“Ten, Pencroff. And how many grains are there to an ear?”

“Faith, I don’t know.”

“Eighty on an average,” said Smith. “So then, if we plant this grain, we shall get from it a harvest of 800 grains; from them in the second year 640,000; in the third, 512,000,000; in the fourth, more than 400,000,000,000. That is the proportion.”

His companions listened in silence. The figures stupefied them.

“Yes, my friend,” resumed the engineer. “Such is the increase of Nature. And what is even this multiplication of a grain of corn whose ears have only 800 grains, compared with the poppy plant, which has 32,000 seeds, or the tobacco plant, which has 360,000? In a few years, but for the numerous enemies which destroy them, these plants would cover the earth. And now, Pencroff,” he resumed, “do you know how many bushels there are in 400,000,000,000 grains?”

“No,” answered the sailor, “I only know that I am an idiot!”

“Well, there will be more than 3,000,000, at 130,000 the bushel!”

“Three millions!” cried Pencroff.

“Three millions.”

“In four years?”

“Yes,” said Smith, “and even in two, if, as I hope, we can get two harvests a year in this latitude.”

Pencroff answered with a tremendous hurrah.

“So, Herbert,” added the engineer, “your discovery is of immense importance. Remember, my friends, that everything may be of use to us in our present situation.”

“Indeed, Mr. Smith, I will remember it,” said Pencroff, “and if ever I find one of those grains of tobacco which increase 360,000 times, I’ll take care not to throw it away. And now what must we do?”

“We must plant this grain,” said Herbert.

“Yes,” added Spilett, “and with the greatest care, for upon it depend our future harvests!”

“Provided that it grows,” said the sailor.

“It will grow,” answered Smith.

It was now the 20th of June, a good time for planting the precious grain. They thought at first of planting it in a pot; but upon consideration, they determined to trust it frankly to the soil. The same day it was planted, with the greatest precaution. The weather clearing a little, they walked up to the plateau above Granite House, and chose there a spot well sheltered from the wind, and exposed to the midday fervor of the sun. This spot was cleared, weeded, and even dug, so as to destroy insects and worms; it was covered with a layer of fresh earth, enriched with a little lime; a palisade was built around it, and then the grain was covered up in its moist bed.

They seemed to be laying the cornerstone of an edifice. Pencroff was reminded of the extreme care with which they had lighted their only match; but this was a more serious matter. The castaways could always have succeeded in obtaining fire by some means or other; but no earthly power could restore that grain of corn, if, by ill fortune, it should perish!
