This is true, and this, perhaps, to the one who considers his action, might have been the way he reasoned.

But he did not reason it, did not reason at all; he acted on impulse.

He could count five objects, and pronounce them by name and number, but he was incapable of reasoning that he would remain in Somo if Nalasu lived, depart from Somo if Nalasu died.

He merely departed from Somo because Nalasu was dead, and the terrible shell-fire passed quickly into the past of his consciousness, while the present became vivid after the way of the present.

Almost on his toes did he tread the wild bushmen's trails, tense with apprehension of the lurking death he know infested such paths, his ears cocked alertly for jungle sounds, his eyes following his ears to discern what made the sounds.
No more doughty nor daring was Columbus, venturing all that he was to the unknown, than was Jerry in venturing this jungle-darkness of black Malaita.
