At the same time he pointed to my uncle, whom we could just see perched upon a knoll, and touched his head to indicate that he was mad.
We took the long way round the shore, for I feared to excite my uncle if we struck across the island; and as we walked, I had time enough to mature the little dramatic exhibition by which I hoped to satisfy my doubts.

Accordingly, pausing on a rock, I proceeded to imitate before the negro the action of the man whom I had seen the day before taking bearings with the compass at Sandag.

He understood me at once, and, taking the imitation out of my hands, showed me where the boat was, pointed out seaward as if to indicate the position of the schooner, and then down along the edge of the rock with the words 'Espirito Santo,' strangely pronounced, but clear enough for recognition.

I had thus been right in my conjecture; the pretended historical inquiry had been but a cloak for treasure-hunting; the man who had played on Dr.Robertson was the same as the foreigner who visited Grisapol in spring, and now, with many others, lay dead under the Roost of Aros: there had their greed brought them, there should their bones be tossed for evermore.

In the meantime the black continued his imitation of the scene, now looking up skyward as though watching the approach of the storm now, in the character of a seaman, waving the rest to come aboard; now as an officer, running along the rock and entering the boat; and anon bending over imaginary oars with the air of a hurried boatman; but all with the same solemnity of manner, so that I was never even moved to smile.
