We were again much puzzled concerning the form of industry which gave rise to such a large establishment as Sharmá. Agriculture was suggested and rejected; and we finally resolved that it was a branch-town that supplied ore to the great smelting-place and workshop of the coast, 'Aynúnah, and possibly carbonate of lime to serve for flux. The distance along the winding Wady, between the settlement and the sea westward, where the watercourse ends in sand-heaps, is seven to eight miles, and the coast shows no sign of harbour or of houses. About three miles, however, to the northwest is the admirable Bay of 'Aynu'nah, unknown to the charts. Defended on both sides by sandspits, and open only between the west and the north-west, where reefs and shoals allow but a narrow passage, its breadth across the mouth from east to west measures at least five thousand metres, and the length inland, useful for refuge, is at least three thousand. At the bottom of this noble Límán, the Kolpos so scandalously abused by the ancients, are three sandy buttresses metalled with water rolled stones, and showing traces of graves. Possibly here may have been the site of an ancient settlement. The Arabs call the southern anchorage, marked by a post and a pit of brackish water, El-Musaybah or Musaybat Sharmá. Its only present use seems to be embarking bundles of rushes for mat-making in Egypt. The north-eastern end of the little gulf is the Gád (Jád), or Mersá of El-Khuraybah, before described as the port of 'Aynu'nah.
