The little hill alluded to as marking the south-east angle of the lake, I again saw; but so indistinctly, though the atmosphere was very clear, that I imagined it to be at least forty miles distant. It is due east of my station on Observatory Hill. I further draw my conclusions from the fact, that all the hills on the country are much about the same height--two or three hundred feet above the basial surface of the land; and I could only see the top of the hill like a hazy brown spot, contrasted in relief against the clear blue sky. Indeed, had my attention not been drawn to it, I should probably have overlooked it, and have thought there was only a sea horizon before me. On facing to the W.N.W., I could only see a sea horizon; and on inquiring how far back the land lay, was assured that, beyond the island of Ukéréwé, there was an equal expanse of it east and west, and that it would be more than double the distance of the little hill before alluded to, or from eighty to one hundred miles in breadth.[59] On my inquiring about the lake's length, the man faced to the north, and began nodding his head to it; at the same time he kept throwing forward his right hand, and, making repeated snaps of his fingers, endeavoured to indicate something immeasurable; and added, that nobody knew, but he thought it probably extended to the end of the world. To the east of the Observatory, a six hours' journey, probably fourteen or fifteen miles, the village of Sukuma is situated, and there canoes are obtainable for crossing to Ukéréwé, which island being six hours' paddling, and lying due north of it, must give the firth a breadth of about fifteen miles.
