No sooner did the buck see that I had found him out than he made a sudden
bolt and attempt at escape--very neatly done, but not quick enough to pass
Breaden. This was indeed a disappointment! I had thought it probable that
our guide would lead us anywhere into the sand and try to escape, but I
never guessed that he would tantalise us as he had done. In any case, so
long as he was with us, we must some time get water--and we had no
intention of letting him escape. With a rope we secured him and watched
in turn all through the night.

Never were jailers more vigilant, for that black-fellow meant our lives.
He tried all means of escape, and never slept the whole night through. He
would lie still with closed eyes for a time, and then make a sudden
struggle to wrench the rope away from his captor; then stealthily with
his foot he tried to push the rope into the fire; then he started rubbing
it on the rock on which we lay; and last of all his teeth were brought
into use. When my turn came to watch, I pretended to sleep, to see what
he would do, and so discovered all his tricks. I confess that I saw with
delight the evident feelings of thirst that before long overcame him--the
salt beef had done its duty; he had had no water of course, for we had
none to give him, and I felt sure that he would be only too eager in the
morning. Nor was I mistaken; long before daylight he showed signs of
distress, and anxiety to go on, standing up and stretching out his long,
thin arm--"Gabbi" (water), he said, pointing in three different
directions, putting his head back and pointing with his chin, making a
noise something between a grunt and a puff. To the East, to the
North-East, and to the South-West from where we had come, he made it
clear that water existed. Evidently we had not been far from his camp
when we caught him, and we could hardly blame him for leading us away
from his own supply, which he rightly judged we and our camels would
exhaust.
