January 3rd. Thermometer 10° on the house-top before the sun rose. This was a striking difference from the temperature of the day before. The Castle walls were about thirty feet thick at bottom, and ten at top, and were composed, as usual, of mud, having small loopholes for musquetry. It formerly had commanded the town, but was at this time in a ruined state. There were wells in the Castle of very salt water. The similarity of the Arab and French names for an embrazure is striking, the former calling it embrāza. Close to the Castle we observed several large stagnant pools of water, which had been caused by taking the clay away to re-erect the walls. I cannot conceive that these places contribute much to the healthiness of the town. The date trees are in and close round the houses. The inhabitants are very little superior to savages, and the Arabic is scarcely understood. The language spoken is Bornou. This being the resting-place of Kafflés from Bornou, Waday, and sometimes Soudan, provisions are always very dear, the inhabitants selling to the half-starved merchants, who arrive from those places, at whatever price they please. Corn is not to be procured; but gaphooly and barley, poor substitutes! are sold at the rate of three quarts for a dollar. Dates are certainly very cheap, a camel load selling at about three quarters of a dollar. The people of Tegerry have not the custom of burying their dates as in Morzouk, but put them in bins built for that purpose in their houses, and cover or mix them with sand: others keep them on the flat roofs, as there is no fear of their being injured by rain. A few years ago this country was famed for the excesses committed by the inhabitants, who robbed, and not unfrequently murdered, travellers. Even large Kafflés were not secure from them, until Mukni took several into slavery, and otherwise regulated them.
