At the termination of the second week, Mark and Betts held a council on the subject of their future proceedings. At this consultation it was decided that it would be better to finish the picking up of a considerable plot of ground, one of at least half an acre in extent, that was already commenced, within the crater, scatter their compost over it, and spade all up together, and plant, mixing in as much of the sea-weed as they could conveniently spade under. Nothwithstanding their success in finding the loam, and this last discovery of a means of getting sea-weed in large supplies to the Reef, Mark was not very sanguine of success in his gardening. The loam appeared to him to be cold and sour, as well as salt, though a good deal freshened by the rain since it was put in the crater; and he knew nothing of the effects of guano, except through the somewhat confused accounts of Bob. Then the plain of the crater offered nothing beside a coarse and shelly ashes. These ashes were deep enough for any agricultural purpose, it is true, for Mark could work a crowbar down into them its entire length; but they appeared to him to be totally wanting in the fertilizing principle. Nor could he account for the absence of everything like vegetation, on or about the reef, if the elements of plants of any sort were to be found in the substances of which it was composed. He had read, however, that the territory around active volcanoes, and which was far enough removed from the vent to escape from the destruction caused by lava, scoriæ and heat, was usually highly fertile, in consequence of the ashes and impalpable dust that was scattered in the air; but seeing no proofs of any such fertility here, he supposed that the adjacent sea had swallowed up whatever there might have been of these bountiful gifts. With these impressions, it is not surprising that Mark was disposed to satisfy himself with a moderate beginning, in preference to throwing away time and labour in endeavouring to produce resources which after all would fail them.
Mark's plan, as laid before his companion, on the occasion of the council mentioned, was briefly this:--He proposed to pass the next month in preparing the half-acre they had commenced upon, and in getting in seed; after which they could do no more than trust their husbandry to Providence and the seasons. As soon as done with the tillage, it was his idea that they ought to overhaul the ship thoroughly, ascertain what was actually in her, and, if the materials of the boat mentioned by Betts were really to be found, to set that craft up as soon as possible, and to get it into the water. Should they not find the frame and planks of the pinnace, as Betts seemed to think they would, they must go to work and get out the best frame they could themselves, and construct such a craft as their own skill could contrive. After building such a boat, it was Mark's opinion that he and Bob could navigate her across that tranquil ocean, until they reached the coast of South America, or some of the islands that were known to be friendly to the white man; for, fifty yearns ago, it will be remembered, we did not possess the same knowledge of the Pacific that we possess to-day, and mariners did not trust themselves always with confidence among the natives of its islands. With this plan pretty well sketched out, then, our mariners saw the first month of their captivity among the unknown reefs of this remote quarter of the world, draw to its close.
