Two or three men mounted, and that brought all the kneeling camels to their feet.

One of Ali Baba's sons caught the beast assigned to me, brought him round to the gate, and began _nakhing_ him to make him kneel again.

But I know one or two things about Arabs and their ways of assessing humanity.
Knowledge is for use.
"Do you mistake me for a cripple ?" I asked, and instead of continuing to _nakh_ in the camel language he pulled the beast's head down.
The trick is simple enough.

You put your foot on the hollow of the camel's neck and swing into the saddle as he raises his head again.

Men used to the desert despise you if you have to make your mount kneel in order to get on his back, pretty much as horsemen of other lands despise the tender foot who can't rope and saddle his own pony.
