Jerry Rolfe glared at her, his lips working furiously to no effect. He could not speak; and Bill Blunt, who had caught question and answer, seemed in as bad case. They sought each other's eyes, and the silent interchange of thought between them solved the puzzle, at least as far as the mate was concerned. He grew hot and almost choked; but his lips could only utter:

"Naval service? Hell!"

He muttered an apology, but for the rest of the journey Natalie walked in absolute bewilderment. She could have no idea of the effect of her reply, except as outwardly evidenced in the mate's attitude. She could not know that in the breast of Rolfe, as in that of Bill Blunt, she had resurrected the demon of distrust towards Vandersee. All the voyage's suspicion that had troubled Rolfe resurged to the top now; knowing that Barry had been taken by supposed navy officers, the honest mate saw no room for doubt that the big Hollander had deliberately insinuated himself into the second mate's berth aboard the Barang for no other purpose than to defeat his skipper. And now he had done it properly. Jerry Rolfe was sure of it. He told his decision to Blunt, who knew Vandersee by report only; and the old sea-dog replied characteristically,—by spitting into his palms and loosening his cutlass in the sheath with a creepy rasp and crash.

Natalie Sheldon sensed the strain that had come upon her escorts, and she felt less at ease in her journey. Never once had she faltered or complained, though she was sadly hampered by her totally unsuitable garments for such a walk. In the gloomy forest the heat was stifling; the trackless jungle was full of creeping life; at every step the feet tripped over fallen logs or crunched with shivery suggestion into rotten shells of storm-torn tree limbs. Bright eyes gleamed at them through the thickets, to vanish swiftly; monkeys in the foliage overhead chattered and howled, swinging from tree to tree in alarm, and glaring down upon the intruders with faces convulsed with rage.

The girl shuddered violently when a thick, gorged snake squirmed from under her feet and scrawled like a monstrous slug into a bush. She simply must talk, or drop, she thought, so attempted Jerry Rolfe again.

"Mr. Rolfe, I don't understand why you are upset at what I said concerning Mr. Vandersee," she ventured.

"Huh," grunted Rolfe. "Naval man, you said, didn't you?"

"Why, yes. But how can that make you so fierce and grumpy?"

Old Bill Blunt grinned happily at her tone. He too had felt the oppressiveness of a speechless march. Sufficient for the moment being sufficient for him, the old salt had long since put aside all thoughts of Vandersee and the Holland Navy, content to have all the trouble in one parcel when it should come. He wanted to chatter, and cared nothing what about.

"Be we grumpy, Missy?" he chuckled. "Then bust me binnacle if we ain't swabs! Asks yer pardon, then—"
