With one final wave of his cigar to the gesticulating Joao and the grinning women he turned his back on the town and faced the little-known river and the inscrutable jungle. But neither his eyes nor his thoughts traveled beyond the bow of the boat. Through narrowed lids he studied the swaying paddlers and the piratical José. And in his mind echoed the whispered warning of Joao, delivered during the effusive embrace at parting: "Comrade, watch those _bastardos Peruanos_." CHAPTER VI. IN THE NIGHT WATCH Day by day the long canoe crawled into the vast unknown. Day by day the down-flowing jungle river pushed steadily, sullenly against its prow, as if striving to repel the invasion of its secret places by the fair-skinned men of another continent. Day by day it slid past in resentful impotence, conquered by the swinging blades of the Peruvian _bogas_. And day by day the close companionship of canoe and camp seemed to weld the voyagers into one compact unit. Through hours of blazing sun, when the mercury of the thermometer which Knowlton had hung inside the shady _toldo_ cabin fluctuated well above 100 degrees, the hardy crew forged on. Through drenching rains they still hung doggedly to their work, suspending it only when the water fell in such drowning quantities that they were forced to tie up hastily to shore and seek cover in order to breathe. When sunset neared they picked with unerring eye a spot fit for camping, attacked the bush with whirling machetes, cleared a space, threw up pole frameworks, swiftly thatched them with great palm leaves, and thus created from the jungle two crude but efficient huts--one for themselves and one for their _patrones_. When night had shut down and all hands squatted around the fire in a nightly smoke talk they regaled their employers with wild tales of adventures in bush and town, some of which were not at all polite, but all of which were mightily interesting. And despite all discomforts, fatigue, and the minor incidents and accidents which often lead fellow travelers in the wilderness to bickering and bitterness, no friction developed between the men of the north and the men of the south. Not that the Peruvians were at all obsequious or servile. They were a reckless, lawless, Godless gang, perpetually bearing themselves with the careless insolence which had characterized them at first, blasphemous of speech toward one another--but never toward the North Americans. Disputes arose among them with volcanic suddenness, and more than once knives were half drawn, only to be slipped back under the tongue-lashing of the hawk-nosed _puntero_, José, who damned the disputants completely and promised to cut out the bowels of any man daring to lift his blade clear of its sheath. Five minutes afterward the fire eaters would be on as good terms as ever, shrugging and grinning at their passengers--particularly Tim, who, shaking his head disgustedly, would grumble: "Aw, pickles! Another frog fight gone bust!"
