_Steamship 'Bentinck,' off Socotra.--May 19th_.--I left my last letter at Aden. We landed there at about four P.M., under a salute from an Indian man-of-war sloop and the fort, to which latter place I was conveyed in a carriage which the Governor sent for me. It was most fearfully hot. The hills are rugged and grand, but wholly barren; not a sign of vegetation, and the vertical rays of a tropical sun beating upon them. The whole place is comprised in a drive around the hills of some three or four miles, beyond which the inhabitants cannot stray without the risk of being seized by the Arabs. I cannot conceive a more dreary spot to dwell in, though the Governor assured me that the troops are healthy. He received me very civilly, and insisted that I should remain with him until the steamer sailed, which involved leaving his abode (the cantonment) at about half-past three in the morning. He took me to see some most extraordinary tanks which he has recently discovered, and which must have been constructed with great care and at great expense, at some remote period, in order to collect the rain-water which falls at rare intervals in torrents. These tanks are so constructed that the overflow of the upper one fills the lower, and in this way, when the fall is considerable, a great quantity can be gathered. They were all filled with rubbish, and it is very possible that there may be many besides these which have been already discovered, but when they are cleared out they are in perfect preservation. Some of them are of great capacity, and it is difficult to understand how they come to have been filled up so completely. The Governor told me that he had, a few months before, driven in his gig over the largest, which I went with him to see. At that time he had no idea of its existence. [Sidenote: Gloomy prospects.] _May 22nd_.--As each of these wearisome days passes, I cannot help being more and more determined that, in so far as it rests with me, this voyage shall not have been made for nothing. However, the issues are in higher hands. _Sunday, 24th_.--We are now told we shall reach Ceylon in two days.... I have got dear Bruce's[4] large speaking eyes beside me while I am writing, and mine (ought I to confess it) are very dim, while all these thoughts of home crowd upon me. There is nothing congenial to me in my present life. I have no elasticity of spirits to keep up with the younger people around me. It may be better when the work begins; but I cannot be sanguine even as to that, for the more I read of the blue-books and papers with which I have been furnished, the more embarrassing the questions with which I have to deal appear.
