ourselves to be seen anywhere. Off again at sunset, we travelled the whole night through, my compass at midnight showing me that we were, if anything, travelling towards the east, when our direction should certainly have been south-west. At our next halt I spoke to Ismail again, but Hassan convinced him of his infallibility in desert routes. The following morning, the 11th, there was no disguising the fact about our direction: the regular guides travel by the stars at night-time, but they laugh at the little niceties between the cardinal points, as Hassan laughed at me when I tried to get him to believe in the sand diagram I showed him, with the object of proving to him that a divergence increases the further you get away from the starting-point. El Amin now joined me in saying that he thought we were on the wrong road, but Hassan was prepared. He had, he said, during the night, led us further into the desert to again break our trail, and that he was now leading us to the regular road. El Amin replied that it was his opinion that Hassan had lost the road in the night, and now was trying to find it. This led to a lively discussion and an exchange of compliments, which almost ended in a nasty scuffle, as some were siding with Hassan and others with El Amin.
Acting upon my advice, men were sent out east and west to pick up the regular caravan route. Hassan declared that a branch of the regular road would be found to the east, Amin and I declared for the west. Hassan took two men east, and Amin, accompanied by two others, went west. About an hour after sunset
