Most of the men who go with us to Damerghou and forward to Tesaoua will find another wife and family in both these places. This is a regular emigration of males, not the accidental departure of fathers and husbands. These gentlemen pass half the year in Soudan and half in Aheer. The system does not appear to be advantageous to the increase of population: the wives of these birds of passage hardly bear two children a-piece. Indeed there are very few children in Tintalous. We have not yet sufficient data or experience for a conclusion on this part of statistics; but, up to the present, all that we have seen in Africa during this journey exhibits it as singularly miserable and destitute of population. We can hear of no man, not even a sultan with his fifty female slaves, having more than four or five children. As for the poor, one or two are all that they can bring up. Whence, then, comes the supply of slaves? So far as this part of Africa is concerned I may observe, in reply, that the annual number of slaves brought is exceedingly limited, amounting only to a few thousands. When we get nearer the western coast, we shall probably be able to account for the supplies of slaves which are transported across the Atlantic. This afternoon a well was commenced near our tents. The digging of a well is an important matter; his highness En-Noor, therefore, vouchsafed his presence. A number of the excavators came to me to beg for sugar. I brought out a piece of white loaf sugar, and broke it into thirty pieces or so; then ordered one of them to divide it fairly amongst themselves: but this was impossible. Anything like fairness amongst the Kailouees, all of whom are addicted to thieving (a habit acquired from Soudan), was out of the question. As soon as I rose from the ground, after breaking the sugar on a leathern apron, there was a general rush upon it, and some got a great deal and others none. Was not this a fine miniature picture of mankind? _24th._--En-Noor paid me a very early visit, and drank coffee. I heard that a courier to Mourzuk would cost forty dollars. I begin to learn a little Soudanese; there are some beautiful soft words in it. Yusuf says there is no name for God in this language; but his statement requires further examination. From what we learn respecting Barth's reception at Aghadez, it would appear that the people were disposed to look upon him with the same complacency as they are wont to regard the pagans, or En-sara as they call them, of Gouber and Maradee. Indeed, the Tanelkums and Kailouees consider that we shall be well received by our brethren, the pagans of Soudan.
