enabled at the same time to note down the information which I had been able to pick up. During these occupations I was greatly pleased with the companionship of a diminutive species of finches which frequent all the rooms in Ágades, and, as I may add from later experience, in Timbúktu also; the male, with its red neck, in particular looks extremely pretty. The poults were just about to fledge. _Sunday, October 27._—There was one very characteristic building in the town, which, though a most conspicuous object from the terrace of our house, I had never yet investigated with sufficient accuracy. This was the mesállaje, or high tower rising over the roof of the mosque. The reason why this building in particular (the most famous and remarkable one in the town) had been hitherto observed by me only from a distance, and in passing by, must be obvious. Difference of religious creed repelled me from it; and so long as the town was full of strangers, some of them very fanatical, it was dangerous for me to approach it too closely. I had often inquired whether it would not be possible to ascend the tower without entering the mosque; but I had always received for answer that the entrance was locked up. As soon, however, as the Sultan was gone, and when the town became rather quiet, I urged Hámma to do his best that I might ascend to the top of this curious building, which I represented to him as a matter of the utmost importance to me, since it would enable me not only to control my route by taking a few angles of the principal elevations round the valley Aúderas, but also to obtain a distant view over the country towards the west and south, which it was not my good luck to visit myself. To-day Hámma promised me that he would try what could be done. [Illustration]
