Hazel in the meantime heightened his own mud banks in the center, and set up brick fireplaces with hearth and chimney; one on each side; and now did all the cooking; for he found the smoke from wood made Miss Rolleston cough. He also made a number of pigeon-holes in his mud walls and lined them with clay. One of these he dried with fire, and made a pottery door to it, and there kept the lucifer-box. He made a vast number of bricks, but did nothing with them. After several failures he made two large pots, and two great pans, that would all four bear fire under them, and in the pans he boiled sea-water till it all evaporated and left him a sediment of salt. This was a great addition to their food, and he managed also to put by a little. But it was a slow process.
He made a huge pair of bellows, with a little assistance from Miss Rolleston; the spout was a sago-stick, with the pith driven out, and the substitute for leather was the skin of a huge eel he found stranded at the east point.
Having got his bellows and fixed them to a post he drove into the ground, he took for his anvil a huge flint stone, and a smaller one for hammer; heated his old iron to a white heat, and hammered it with a world of trouble into straight lengths; and at last with a portion of it produced a long saw without teeth, but one side sharper than the other. This, by repeated experiments of heating and immersing in water, he at last annealed; and when he wanted to saw he blew his embers to a white heat (he kept the fire alive now night and day); heated his original saw red-hot, and soon sawed through the oleaginous woods of that island. If he wanted to cut down a tree in the jungle, he put the bellows and a pot of embers on his cart with other fuel, and came and lighted the fire under the tree and soon had it down. He made his pickax in half an hour, but with his eyes rather than his hands. He found a young tree growing on the rock, or at least on soil so shallow that the root was half above ground and at right angles to the stem. He got this free up, shortened the stem, shaped the root, shod the point with some of his late old iron; and with this primitive tool, and a thick stake baked at the point, he opened the ground to receive twelve stout uprights, and he drove them with a tremendous mallet made upon what might be called the compendious or Hazelian method; it was a section of a hard tree with a thick shoot growing out of it, which shoot, being shortened, served for the handle.
By these arts he at last saw a goal to his labors. Animal food, oil, pitch, ink, paper, were still wanting; but fish were abundant, and plantains and cocoanuts stored. Above all, Helen's hut was now weather-tight. Stout horizontal bars were let into the trees, and, being bound to the uprights, they mutually supported each other; smaller horizontal bars at intervals kept the prickly ramparts from being driven in by a sudden gust. The canvas walls were removed and the nails stored in a pigeon-hole, and a stout network substituted, to which huge plantain leaves were cunningly fastened with plantain thread. The roof was double: first, that extraordinary mass of spiked leaves which the four trees threw out, then several feet under that the huge piece of matting the pair had made. This was strengthened by double strips of canvas at the edges and in the center, and by single strips in other parts. A great many cords and strings made of that wonderful grass were sewn to the canvas-strengthened edges, and so it was fastened to the trees and fastened to the horizontal bars.
When this work drew close to its completion, Hazel could not disguise his satisfaction.
But he very soon had the mortification of seeing that she for whom it was all done did not share his complacency. A change took place in her; she often let her work fall, and brooded. She spoke sometimes sharply to Mr. Hazel, and sometimes with strained civility. She wandered away from him and from his labors for her comfort, and passed hours at Telegraph Point, eying the illimitable ocean. She was a riddle. All sweetness at times, but at others irritable, moody, and scarce mistress of herself. Hazel was sorry and perplexed, and often expressed a fear she was ill. The answer was always in the negative. He did not press her, but worked on for her, hoping the mood would pass. And so it would, no doubt, if the cause had not remained.
Matters were still in this uncomfortable and mysterious state when Hazel put his finishing stroke to her abode.
He was in high spirits that evening, for he had made a discovery; he had at last found time for a walk, and followed the river to its source, a very remarkable lake in a hilly basin. Near this was a pond, the water of which he had tasted and found it highly bituminous; and, making further researches, he had found at the bottom of a rocky ravine a very wonderful thing--a dark resinous fluid bubbling up in quite a fountain, which, however, fell down again as it rose, and hardly any overflowed. It was like thin pitch.
Of course in another hour he was back there with a great pot, and half filled it. It was not like water, it did not bubble so high when some had been taken; so he just took what he could get. Pursuing his researches a little further he found a range of rocks with snowy summits apparently; but the snow was the guano of centuries. He got to the western extremity of the island, saw another deep bay or rather branch of the sea, and on the other side of it a tongue of high land running out to sea. On that promontory stood a gigantic palmtree. He recognized that with a certain thrill, but was in a great hurry to get home with his pot of pitch; for it was in truth a very remarkable discovery, though not without a parallel. He could not wait till morning, so with embers and cocoanut he made a fire in the bower, and melted his pitch, which had become nearly solid, and proceeded to smear the inside of the matting in places, to make it thoroughly watertight.
