What hungry-looking creatures they were!
How their eyes gleamed!
The boys wondered what the hyenas would do.
They watched to see.
The big-nosed rhinoceros went stupidly browsing along the edge of the cliff.
He did not see the hyenas.
The hyenas had learned that the rhinoceros could not see far away, and now they were taking advantage of this.
They were too cowardly to risk a fair fight.
Even the mammoth and sabre-tooth did not like to encounter the big-nosed rhinoceros.
Even they could not pierce his thick, heavy skin.
