“I did not think they would attack, for several obvious reasons. The thick fog was one. If they left the bank in their canoes they would get lost in it, as we would be if we attempted to move. Still, I had also judged the jungle of both banks quite impenetrable—and yet eyes were in it, eyes that had seen us. The riverside bushes were certainly very thick; but the undergrowth behind was evidently penetrable. However, during the short lift I had seen no canoes anywhere in the reach—certainly not abreast of the steamer. But what made the idea of attack inconceivable to me was the nature of the noise—of the cries we had heard. They had not the fierce character boding immediate hostile intention. Unexpected, wild, and violent as they had been, they had given me an irresistible impression of sorrow. The glimpse of the steamboat had for some reason filled those savages with unrestrained grief. The danger, if any, I expounded, was from our proximity to a great human passion let loose. Even extreme grief may ultimately vent itself in violence—but more generally takes the form of apathy....

“You should have seen the pilgrims stare! They had no heart to grin, or even to revile me: but I believe they thought me gone mad—with fright, maybe. I delivered a regular lecture. My dear boys, it was no good bothering. Keep a lookout? Well, you may guess I watched the fog for the signs of lifting as a cat watches a mouse; but for anything else our eyes were of no more use to us than if we had been buried miles deep in a heap of cotton-wool. It felt like it, too—choking, warm, stifling. Besides, all I said, though it sounded extravagant, was absolutely true to fact. What we afterwards alluded to as an attack was really an attempt at repulse. The action was very far from being aggressive—it was not even defensive, in the usual sense: it was undertaken under the stress of desperation, and in its essence was purely protective.
