The Bedouin were very unruly about the packing. We could not get our most needful things kept handy, and they liked to pack our bread with their fish, and the waterskins anywhere among our bedding. Mokaik did not seem to have much authority over the various owners of the camels, and they were always quarrelling among themselves, robbing each other of light loads and leaving some heavy thing, that no one wished for, lying on the ground; this often occasioned re-packing. They had for each camel a stout pair of sticks with strong ropes attached, and having bound a bundle of packages to each stick, two men lifted them and wound the ropes round the sticks over a very tiny pack-saddle and a mass of untidy rags. When we arrived they liked to simply loose the ropes from the sticks and let the baggage clatter to the ground and lead away the camels. As they would not be persuaded to sort the things, and as twenty-two camels cover a good deal of space, it was like seeking the slain on a battlefield when we had to wander about having every bundle untied. Three days' camel-riding up one of the short valleys which lead towards the high table-land offered little of interest beyond arid, igneous rocks, and burnt-up, sand-covered valleys, with distorted strata on either side. Here and there, where warm volcanic streams rise out of the ground, the wilderness is converted into a luxuriant garden, in which palms, tobacco, and other green things grow. One of the scrub trees which clothe the wilderness is called by the Arabs _rack_, and is used by them for cleaning their teeth. It amused us to chew this as we went along: it is slightly bitter, but cleans the teeth most effectually. There is also a poisonous sort of cucumber, called by the Arabs _madakdak_. They clean out the inside and fill the skin with water, which they drink as a medicine. At Sibeh, which we reached after a very hot ride of twelve or thirteen miles, we found water with scores of camels lying round it, for there were two or three other _kafilas_, or caravans, beside our own. It was dreadfully cold that night, and we could not get at our bag of blankets. Next we entered the narrow, tortuous valley of Howeri, which ascends towards the highland, in which the midday heat was intense; and at our evening halts we suffered not a little from camel-ticks, which abound in the sand, until we learnt to avoid old camping-grounds and not to pitch our tents in the immediate vicinity of the wells. We encamped in a narrow, stony river-bed, between walls of rock, near a little village called Tahiya. There is a good deal of cultivation about. The closeness of the situation made the smell of the dried fish we carried for the camels almost unbearable.
