The party travelled without haste. Before arriving on the Nile, Edgar suggested to the sheik that it would be as well were he to discard his European dress for an Arab one.

"When we were at Damanhour," he said, "I marked how the people scowled at me as I rode through the streets; and as no doubt you will ride into Cairo ere long, it would save trouble were I to be so attired that I should escape notice."

"It would be a good plan," the sheik agreed. "I daresay Sidi can supply you with a suit."

"I can purchase what is needed at the next place we come to," Edgar said, "I have money for any necessity that may arise. Even putting aside the trouble of being constantly questioned, I should prefer the Arab dress, for under this baking sun I think it would be a good deal more comfortable than these English clothes."

Accordingly, at the next town they passed through, Sidi and Edgar went together to the bazaar, and the latter purchased, after the usual amount of bargaining, clothes similar to those worn by his friend. The expense was but small, for the costume of an Arab chief differed but little from those of his followers, except that his burnoose was of finer cotton, and his silken sash of brilliant colours, richer and more showy. With this exception the whole costume was white, and although some of the Arab sheiks wore coloured burnooses, Edgar chose a white one, as both his friend and his father wore that colour. He bought two or three changes of clothes, for he knew that water was often scarce, and that washing of garments could not be indulged in frequently. That night when the camp was pitched he donned his new costume, and placed his pistols in his sash in Arab fashion. Sidi wound his turban for him, and gave him instructions how the clothes were to be worn. Those he had taken off were made into a bundle so that they could be resumed if necessary. He felt rather awkward as with his friend he sallied out from the tent which they now shared between them.

"You look well, Edgar," the sheik said approvingly, "but you will need to stain your arms and legs, and it will be better for you to stain your face and neck also, for you would attract quite as much attention as a white Arab as you would in your European dress."

"I was thinking so myself, sheik; it will be much pleasanter for me to be able to pass anywhere without comment."

"You are taller than I thought," the sheik said; "it had not struck me that you were much taller than Sidi, but I see now that you are as tall as I am."

"I suppose the flowing garments make one look taller," Edgar said. "I have often been surprised, when standing near a native who looked to me a good deal taller than myself, to find that he was really not above my own height."

"My wife shall make a stain for you as soon as she can get the material. There will be no difficulty about that, for we often dye our burnooses brown, especially when we are starting on a long journey."
