When we reached an oasis about noon—sweet water and thirty or forty palm-trees—and simply had to camp there because the camels were exhausted after a night and half a day of strenuous marching, they were still so full of high spirits that they had to work them off somehow; and unwittingly I provided the excuse.

I was on the lee side of a camel, opening a boil in Mujrim's leg with his razor, when I caught sight of one of the younger men trying to burgle the medicine-chest. I yelled at him, and naturally gashed my patient's leg, who rose in giant wrath and with enormous fairness smote the real culprit.

The resulting blasphemous bad language brought Ali Baba to the scene at once as peacemaker, with all the gang behind him; and in a minute they had all joined hands, with Mahommed standing in the center, and were dancing like a lot of pouter-pigeons, singing a new song about Mujrim's leg, and a razor, and blood on the sand, and palm-trees, and a saint, and my superhuman ability to let daylight into the very heart of boils. You don't have to believe any one who tells you that Arabs haven't humor.

There were the ruins of half a dozen mud-walled huts near the spring in that oasis. There had once been a sort of rampart and a gate, but there was hardly enough of that left to show where it stood. The only building still quite intact was a stone tomb of about the height of a man, with a plastered cupola roof; and Ali Baba, who always knew everything, swore that was a great saint's grave, and that there was much virtue and good luck to be gained by praying inside the tomb. So they all took turns to go in and pray fervently—two-bow prayers as they called them—reciting thereafter such scripture as Ali Baba thought suitable and could remember.

Hunting about in the ruins I found indubitable human bones. Ayisha, when asked about it, said that Ali Higg had raided the place several months ago and killed or captured every one.

"Because he is lord of the waters," she explained, and seemed to think that reason unassailable.

There was quite a dispute at that place as to who should stand first guard while the rest of us slept, but Grim settled it by casting lots with date-stones in a way that was new, but that seemed to satisfy every one—especially as the first watch fell to Narayan Singh and me.

"That is because the rest of us said our prayers," explained Ali
Baba piously.

But I think it was really because Grim knew how to play tricks with the date-stones.

The Sikh and I kept making the circuit of the palm-trees and talking to keep each other from getting too sleepy, for there is no time when desire to sleep so loads you down as in the noon heat after a long march. You very often can't sleep then because of the very heat that makes you drowsy; but the glare has been so trying to your eyes that you yearn to shut them, and inertia sits on your spine and shoulders like a load of lead.
