Having arrived at Batna, which is the starting-place for Timgad and also for the desert beyond, I found that there was a good road which the French had built going along a valley under Aurès, but that the distance was over twenty miles. I wasted the daylight bargaining, for no one would drive me twenty miles for less than sixteen shillings. It was late, and in my eagerness to bargain I missed the chance of a daylight march, for it was within an hour of sunset when the night driver who was to start on the Tebessa road (which runs near Timgad) a little later refused me. The poorer people whom I asked told me that no one else was going eastward along that lonely valley, but that, if I were to reach Timgad, I must make a night march of it or wait a night over in Batna itself at an inn. [Sidenote: Lamboesis] Adventure is never to be refused, so I went out eastward alone under the evening, and I was well rewarded, though I went hungry for hours and was afoot nearly all the way, for I saw a great sight under the sunset, and I met a man I shall never meet again. The sight I saw was Lambèse, which was called Lamboesis by the Romans, and this is what stamps it upon the mind of a lonely man before nightfall: not what remains, for hardly anything remains, but that the fragments which remain of it should be so far apart. [Sidenote: The Praetorian Tower] There is a sort of long cup or hollow here pointing at a spur of the Atlas—that high mountain which holds up the sky. The big lift of Aurès is on one side of this hollow, mixing into the clouds, and on the other are isolated and uninhabited high hills. The very floor of this valley is as high as the top of Cader Idris is in Wales; the heights beyond are as high as the Pyrenees; and an air of desertion haunts the place. It is impossible to forget that the Sahara is near by, down beyond the crest of the range. For though the land is muddy and the sky full of rough clouds and rain, yet the rain seems to make no grass and the land is bare. In such a world there stands up before one a square and hardly ruined tower. [Sidenote: The Vastness of Lambèse]
