It did not appear to be among the branches of the durion, but as if in the trunk of the tree; and in the interval of silence that succeeded his first quick exclamation, they could hear a hissing sound, such as might proceed from the throat of a goose when some stranger intrudes upon the domain of the farmyard.

As it was carried down the smooth stem of the durion, which acted as a conductor, the spectators underneath guessed it was not a goose, but some creature of a less innocent kind.
"A snake, be japers!" was the conjecture that dropped from the ship-carpenter's lips, while the same thought occurred simultaneously to the others; for they could think of no living thing, other than a serpent, capable of sending forth such a sibilant sound as that just heard.
"What is it, Saloo ?" hailed Captain Redwood; "are you in any danger ?" "No dangee, cappen; only little bit good luck, that all," was the cheering response that restored their confidence.
"How good luck ?" asked the captain, puzzled to think of what fortune could have turned up in their favour so high above their heads.
"You see soon," rejoined the Malay, taking a fresh peg from his girdle, and once more resuming his task at stair-making.
While he was engaged in hammering, and between the resounding strokes, they at the bottom of the tree repeatedly heard the same hissing sound they had taken for the sibilations of a snake, and which they might still have believed to be this, but for a hoarse croaking voice, mingling with the sibilation, which reached their ears at intervals, evidently proceeding from the same throat.
Moreover, as they continued to gaze upward, watching Saloo at his work, they caught sight of something in motion on the trunk, and about a foot above his face.

It was something of a whitish colour and slender shape, pointed like one of the bamboo pegs he was busily driving at.

Now they saw it, and now they did not see it; for whatever it was, it was sunk inside the trunk of the durion-tree, alternately protruding and drawing back.

It was also clear to them, that from this sharp-pointed thing, whether beast, bird, or reptile, came the hissing and hoarse croaking that puzzled them.
"What is it ?" again asked the captain, now no longer anxious or alarmed, but only curious to know what the strange creature could be.
"Buld, cappen--biggee buld." "Oh, a bird, that's all; what sort of bird ?" "Honbill; ole hen hornbill.
