But he had a somewhat discomforting feeling that he knew very little of the real man that lay beneath that saturnine exterior, that there might be elemental depths there which would surprise him if they came to be revealed. This Macro that he knew was to him something in the nature of a sleeping volcano, outwardly quiet but full of hidden fires.

He could imagine no likely grounds for dispute between them. Each worked for the common good, and so far they had shared all things equally and without question. But how would it be as the weeks dragged into months, and the months into years?

So far the rifling of the wreckage had afforded the mate all the outlet he needed for his activities. In ministering to the cravings of the riever spirit that was strong in him it had also supplied their wants in overwhelming abundance. The longer it kept him busy the better, and if it yielded him plunder of value he was entirely welcome to it.

Wulfrey could not imagine his discovering anything out there which could by any possibility lead to any serious difference between them. And yet, in spite of all that, from little glimpses he had caught at times of the strange wild, hidden nature of the man, he was not without doubts as to his absolute congeniality as a sole companion for the rest of his days.

In short he had a vague feeling that, if by any chance they came to loggerheads, Macro might prove an extremely unpleasant person to be shut up with, within bounds so limited as this great bank of sand.

He recognised such feelings, however, as unnecessarily morbid, and ascribed them to the general murkiness of the outlook and over-weariness from the exertions of the last few days. So he tumbled overboard on to the new raft and paddled to the nearer shore, and set off for a brisk walk over the sandhills and along the beach, in search of a more hopeful frame of mind.

Why could they not build a boat? Macro said the coast of Nova Scotia was but a hundred miles or so away. A hundred miles was no great affair, and there was wood among that pile enough to build a thousand boats. So far, indeed, they had not come upon any tools except the rusty axe, for tool-chests probably sank at once on the outer banks where the ships went to pieces.

Still, he would suggest it to Macro. It might prove a further outlet for his energies. If he should by chance find plunder of value out there he might, when he was satiated, favour the idea of an attempt at escape. In fact, plunder without any attempt to utilise it would be absurd.

The opportunity of making his own position clear, and thereby obviating any cause for dispute, occurred that same day.

When, in the afternoon, he saw the mate coming slowly along before the wind, he paddled over to the spit to meet him and found him in great spirits.
