The well was nearly dry, but by descending the gallery we obtained a sufficient supply of cold, pure water. We breakfasted in the shaded doorway, sharing our provisions with a Turcoman boy, who was accompanying his father to Eregli with a load of salt.

Our road now crossed a long, barren pass, between two parts of Karadja Dagh. Near the northern side there was a salt lake of one hundred yards in diameter, sunk in a deep natural basin. The water was intensely saline.

From the slope of the mountain we overlooked another and somewhat deeper plain, extending to the north and west. It was bounded by broken peaks, all of which betrayed a volcanic origin. Far before us we saw the tower on the hill of Kara-bounar, our resting-place for the night. The road thither was over a barren plain, cheered here and there by patches of a cushion-like plant, which was covered with pink blossoms. Mr. Harrison scared up some coveys of the frankolin, a large bird resembling the pheasant, and enriched our larder with a dozen starlings.

Near it are the remains of a magnificent khan-fortress, said to have been built by the eunuch of one of the former Sultans. As there was no water in the
