The Mysterious Island, Jules Verne [classic novels .txt] 📗

It was Top who had provided these points by bringing in a porcupine, poor game enough, but of an undeniable value, thanks to the quills with which it bristled. These quills were firmly fastened to the ends of the arrows, and their flight was guided by feathering them with the cockatoo’s feathers. The reporter and Herbert soon became expert marksmen, and all kinds of game, such as cabiais, pigeons, agoutis, heath-cock, etc., abounded at the Chimneys. Most of these were killed in that part of the forest upon the left bank of the Mercy, which they had called Jacamar Wood, after the kingfisher which Pencroff and Herbert had pursued there during their first exploration.

The meat was eaten fresh, but they preserved the hams of the cabiai by smoking them before a fire of green wood, having made them aromatic with odorous leaves. Thus, they had nothing but roast after roast, and they would have been glad to have heard a pot singing upon the hearth; but first they must have the pot, and for this they must have the oven.

During these excursions, the hunters noticed the recent tracks of large animals, armed with strong claws, but they could not tell their species; and Smith cautioned them to be prudent, as, doubtless, there were dangerous beasts in the forest.

He was right. For one day Spilett and Herbert saw an animal resembling a jaguar. But, fortunately, the beast did not attack them, as they could hardly have killed it without being themselves wounded. But, Spilett promised, if he should ever obtain a proper weapon, such as one of the guns Pencroff begged for, that he would wage relentless war on all ferocious beasts and rid the island of their presence.

They did not do anything to the Chimneys, as the engineer hoped to discover, or to build, if need be, a more convenient habitation, but contented themselves by spreading fresh quantities of moss and dry leaves upon the sand in the corridors, and upon these primitive beds the tired workmen slept soundly. They also reckoned the days already passed on Lincoln Island, and began keeping a calendar. On the 5th of April, which was a Wednesday, they had been twelve days upon the island.

On the morning of the 6th, the engineer with his companions met at the place where the bricks were to be baked. Of course the operation was to be conducted in the open air, and not in an oven, or, rather, the pile of bricks would in itself form a bake-oven. Carefully-prepared faggots were laid upon the ground, surrounding the tiers of dry bricks, which formed a great cube, in which air-holes had been left. The work occupied the whole day, and it was not until evening that they lit the fire, which all night long they kept supplied with fuel.

The work lasted forty-eight hours, and succeeded perfectly. Then, as it was necessary to let the smoking mass cool, Neb and Pencroff, directed by Mr. Smith, brought, on a hurdle made of branches, numerous loads of limestone which they found scattered in abundance to the north of the lake. These stones, decomposed by heat, furnished a thick quick-lime, which increased in bulk by slacking, and was fully as pure as if it had been produced by the calcimation of chalk or marble. Mixed with sand in order to diminish its shrinkage while drying, this lime made an excellent mortar.

By the 9th of April the engineer had at his disposal a quantity of lime, all prepared, and some thousands of bricks. They, therefore, began at once the construction of an oven, in which to bake their pottery. This was accomplished without much difficulty; and, five days later, the oven was supplied with coal from the open vein, which the engineer had discovered near the mouth of Red Creek, and the first smoke escaped from a chimney twenty feet high. The glade was transformed into a manufactory, and Pencroff was ready to believe that all the products of modern industry would be produced from this oven.

Meantime the colonists made a mixture of the clay with lime and quartz, forming pipe-clay, from which they moulded pots and mugs, plates and jars, tubs to hold water, and cooking vessels. Their form was rude and defective, but after they had been baked at a high temperature, the kitchen of the Chimneys found itself provided with utensils as precious as if they were composed of the finest kaolin.

We must add that Pencroff, desirous of knowing whether this material deserved its name of pipe-clay, made some large pipes, which he would have found perfect, but for the want of tobacco. And, indeed, this was a great privation to the sailor.

“But the tobacco will come like everything else,” he would say in his hopeful moments.

The work lasted until the 15th of April, and the time was well spent. The colonists having become potters, made nothing but pottery. When it would suit the engineer to make them smiths they would be smiths. But as the morrow would be Sunday, and moreover Easter Sunday, all agreed to observe the day by rest. These Americans were religious men, scrupulous observers of the precepts of the Bible, and their situation could only develop their trust in the Author of all things.

On the evening of the 15th they returned permanently to the Chimneys, bringing the rest of the pottery back with them, and putting out the oven fire until there should be use for it again. This return was marked by the fortunate discovery by the engineer of a substance that would answer for tinder, which, we know, is the spongy, velvety pulp of a mushroom of the polypore family. Properly prepared it is extremely inflammable, especially when previously saturated with gunpowder, or nitrate or chlorate of potash. But until then they had found no polypores, nor any fungi that would answer instead. Now, the engineer, having found a certain plant belonging to the mugwort family, to which belong wormwood, mint, etc., broke off some tufts, and, handing them to the sailor, said:—

“Here, Pencroff, is something for you.”

Pencroff examined the plant, with its long silky threads and leaves covered with a cotton-like down.

“What is it, Mr. Smith?” he asked. “Ah, I know! It’s tobacco!”

“No,” answered Smith; “it is Artemesia wormwood, known to science as Chinese mugwort, but to us it will be tinder.”

This mugwort, properly dried, furnished a very inflammable substance, especially after the engineer had impregnated it with nitrate of potash, which is the same as saltpetre, a mineral very plenty on the island.

This evening the colonists, seated in the central chamber, supped with comfort. Neb had prepared some agouti soup, a spiced ham, and the boiled corms of the “caladium macrorhizum,” an herbaceous plant of the arad family, which under the tropics takes a tree form. These corms, which are very nutritious, had an excellent flavor, something like that of Portland sago, and measurably supplied the place of bread, which the colonists were still without.

Supper finished, before going to sleep the party took a stroll upon the beach. It was 8 o’clock, and the night was magnificent. The moon, which had been full five days before, was about rising, and in the zenith, shining resplendent above the circumpolar constellations, rode the Southern Cross. For some moments the engineer gazed at it attentively. At its summit and base were two stars of the first magnitude, and on the left arm and the right, stars, respectively, of the second magnitude and the third. Then, after some reflection, he said:—

“Herbert, is not to-day the 15th of April?”

“Yes, sir,” answered the lad.

“Then, if I am not mistaken, to-morrow will be one of the four days in the year when the mean and real time are the same; that is to say, my boy, that to-morrow, within some seconds of noon by the clocks, the sun will pass the meridian. If, therefore, the weather is clear, I think I will be able to obtain the longitude of the island within a few degrees.”

“Without a sextant or instruments?” asked Spilett.

“Yes,” replied the engineer. And since it is so clear, I will try to-night to find our latitude by calculating the height of the Cross, that is, of the Southern Pole, above the horizon. You see, my friends, before settling down, it will not do to be content with determining this land to be an island; we must find out its locality.”

“Indeed, instead of building a house, it will be better to build a ship, if we are within a hundred miles of an inhabited land.”

“That is why I am now going to try to get the latitude of the place, and to-morrow noon to calculate the longitude.”

If the engineer had possessed a sextant, the work would have been easy, as this evening, by taking the height of the pole, and to-morrow by the sun’s passage of the meridian, he would have the co-ordinates of the island. But, having no instruments he must devise something. So returning to the Chimneys, he made, by the light of the fire, two little flat sticks which he fastened together with a thorn, in a way that they could be opened and shut like compasses, and returned with them to the beach. But as the sea horizon was hidden from this point by Claw Cape, the engineer determined to make his observation from Prospect Plateau, leaving, until the next day, the computation of the height of the latter, which could easily be done by elementary geometry.

The colonists, therefore, went to the edge of the plateau which faced the southeast, overlooking the fantastic rocks bordering the shore. The place rose some fifty feet above the right bank of the Mercy, which descended, by a double slope, to the end of Claw Cape and to the southern boundary of the island. Nothing obstructed the vision, which extended over half the horizon from the Cape to Reptile Promontory. To the south, this horizon, lit by the first rays of the moon, was sharply defined against the sky. The Cross was at this time reversed, the star Alpha being nearest the pole. This constellation is not situated as near to the southern as the polar star is to the northern pole; Alpha is about 27° from it, but Smith knew this and could calculate accordingly. He took care also to observe it at the instant when it passed the meridian under the pole, thus simplifying the operation.

The engineer opened the arms of his compass so that one pointed to the horizon and the other to the star, and thus obtained the angle of distance which separated them. And in order to fix this distance immovably, he fastened these arms, respectively, by means of thorns, to a cross piece of wood. This done, it was only necessary to calculate the angle obtained, bringing the observation to the level of the sea so as to allow for the depression of the horizon caused by the height of the plateau. The measurement of this angle would thus give the height of Alpha, or the pole, above the horizon; or, since the latitude of a point on the globe is always equal to the height of the pole above the horizon at that point, the latitude of the island.

This calculation was postponed until the next day, and by 10 o’clock everybody slept profoundly.

CHAPTER XIV.

THE MEASURE OF THE GRANITE WALL—AN APPLICATION OF THE THEOREM OF SIMILAR TRIANGLES—THE LATITUDE OF THE ISLAND—AN EXCURSION TO THE NORTH—AN OYSTER-BED—PLANS FOR THE FUTURE—THE SUN’S PASSAGE OF THE MERIDIAN—THE CO-ORDINATES OF LINCOLN ISLAND.

At daybreak the next day, Easter Sunday, the colonists left the Chimneys and went to wash their linen and clean their clothing. The engineer intended to make some soap as soon as he could obtain some soda or potash and grease or oil. The important question of renewing their wardrobes would be considered in due time. At present they were strong, and able to stand hard wear for at least six months longer. But everything depended on the situation of the island as regarded inhabited countries, and that would be determined this day, providing the weather permitted.

The sun rising above the horizon, ushered in one of those glorious days which seem like the farewell of summer. The first thing to be done was to measure the height of Prospect Plateau above the sea.

“Do you not need another pair of compasses?” asked Herbert, of the engineer.

“No, my boy,” responded the latter, “this time we will try another and nearly as precise a method.”

Pencroff, Neb, and the reporter were busy at other things; but Herbert, who desired to learn, followed the engineer, who proceeded along the beach to the base of the granite wall.

Smith was provided with a pole twelve feet long, carefully measured off from his own height, which he knew to a hair. Herbert carried a
