It was on the sixth day of our journey that, having landed as usual at the first sign of dawn, we were resting in a secluded and shady spot after having partaken of an excellent and substantial breakfast.  I had been sound asleep for some hours, for the sun was well past the meridian, when I was startled into sudden and complete wakefulness, and sprang up with the sensation that I had heard Ama screaming and calling upon me for help.
