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.
