about three miles from the shore, of an oval form, rising in the middle. It seems to me to be of granite; and is called, in the language of the country, Jibbel Siberget, which has been translated the Mountain of Emeralds. Siberget, however, is a word in the language of the Shepherds, who, I doubt, never in their lives saw an emerald; and though the Arabic translation is Jibbel Zumrud, and that word has been transferred to the emerald, a very fine stone, oftener seen since the discovery of the new world, yet I very much doubt, that either Siberget or Zumrud ever meant Emerald in old times.

We landed on a point perfectly desert; at first, sandy like Cosseir, afterwards, where the soil was fixed, producing some few plants of rue or absinthium.

This would have been the case in the present conjuncture. He knew not the name of the place, and perhaps it had no name, but he called it Saiel, which signifies a male acacia-tree; merely because he saw an acacia growing there; and,
