"It were best that you did not approach the ferry until it is getting dark. You would do well to bring a comrade to take the two horses back; Ayala could not use them. One frequently sees women riding on donkeys, but for a peasant woman to be mounted on a horse would be unusual. Besides, we should not know what to do with them here, and they would have to go down every day for water. If you start at noon to-day from Cairo, you will be there on the afternoon of the third day, and if you start again next morning will be here on the sixth day. I will light a fire a short distance from the front of the cave so as to act as a guide to you when you get into the rough ground. If you are not here that night I shall know that she is not coming. I shall say nothing about it to the sheik or Sidi; it is better that they should not be looking forward to it. If she did not come they might be fearing that some misadventure had happened on the journey. In any case, you understand that you are not to propose it to her, but are to remain altogether silent on the subject unless she herself insists on coming."
