And with the strange sixth sense of the accustomed woodsman Sam felt, as they travelled, that something was wrong.  The impression did not come to him through any of the accustomed channels.  In fact, it hardly reached his intellect as yet.  Through long years his intuitions had adapted themselves to their environment.  The subtle influences the forest always disengaged found in the delicately attuned fibres of his being that which vibrated in unison with them.  Now this adjustment was in some way disturbed.  To Sam Bolton the forest was different, and this made him uneasy without his knowing why.  From time to time he stopped suddenly, every nerve quivering, his nostrils wide, like some wild thing alert for danger.  And always the other five senses, on which his mind depended, denied the sixth.  Nothing stirred but the creatures of the wilderness.

Yet always the impression persisted.  It was easily put to flight, and yet it always returned.  Twice, while Dick rested in the comfort of tobacco, Sam made long detours back through the woods, looking for something, he knew not what; uneasy, he knew not why.  Always he found the forest empty.  Everything, well ordered, was in its accustomed place.  He returned to the canoe, shaking his head, unable to rid himself of the sensation of something foreign to the established order of things.

At noon the men drew ashore on a little point of rock.  There they boiled tea over a small fire, and ate the last of their pilot’s bread, together with bacon and the cold meat of partridges.  By now the sun was high and the air warm.  Tepid odours breathed from the forest, and the songs of familiar homely birds.  Little heated breezes puffed against the travellers’ cheeks.  In the sun’s rays their garments steamed and their muscles limbered.

Yet even here Sam Bolton was unable to share the relaxation of mind and body his companion so absolutely enjoyed.  Twice he paused, food suspended, his mouth open, to listen intently for a moment, then to finish carrying his hand to his mouth with the groping of vague perplexity.  Once he arose to another of his purposeless circles through the woods.  Dick paid no attention to these things.  In the face of danger his faculties would be as keenly on the stretch as his comrade’s; but now, the question one merely of difficult travel, the responsibility delegated to another, he bothered his head not at all, but like a good lieutenant left everything to his captain, half closed his eyes, and watched the smoke curl from his brier pipe.

When evening fell the little fish-net was stretched below a chute of water, the traps set, snares laid.  As long as these means sufficed for a food supply, the ammunition would be saved.  Wet clothes were hung at a respectful distance from the blaze.

Sam was up and down all night, uncomfortable, indefinitely groping for the influence that unsettled his peace of mind.  The ghost shadows in the pines; the pattering of mysterious feet; the cries, loud and distant, or faint and near; the whisperings, whistlings, sighings, or crashes; all the thousand ethereal essences of day-time noises that go to make up the Night and her silences—­these he knew.  What he did not know, could not understand, was within himself.  What he sought was that thing in Nature which should correspond.
