If any of the hunters had been within hearing, they would have needed no further signal to tell them that some danger threatened her.
If not within hearing, it would be worse than idle for either of them to cry out again.

They determined, therefore, to remain silent, and keep to their position, in the hope that either their father, the Malay, or Murtagh, might come to their speedy relief.
But they were prudent enough not to expose themselves to any wandering glance of the red gorilla's.

The moment Henry had joined his sister he had hurried her behind the trunk of the tree, and they were now on the side facing toward the forest.

There, by looking through the leaves of some orchideous creepers that wreathed the great stem, they could see the dreaded creature without being seen by it.

Hand in hand, still trembling, they stood silently and cautiously regarding the gorilla and its movements.
Under other and safer circumstances it would have been a curious and interesting spectacle: this gigantic, human-like ape, stretching forth its hairy arms, each full four feet in length--gathering in the heads of the tall water-plants, and munching them in great mouthfuls, then letting the stalks go and sweeping round to collect a fresh sheaf, at intervals wading a pace or two to reach some that were more tempting to its taste.
