There we crouched and watched him.

Presently Umslopogaas, who was a few paces ahead of me, turned and made a sign, and next second I saw him go down on his stomach like a snake, and, taking an opportunity when the sentry's head was turned, begin to work his way through the grass without a sound.
The unconscious sentry commenced to hum a little tune, and Umslopogaas crept on.

He reached the shelter of the mimosa bush unperceived and there waited.

Still the sentry walked up and down.

Presently he turned and looked over the wall into the camp.
