This suspicion was strengthened, a little later on, by the fact that as we approached a certain bend in the river our timoneer edged the canoe in toward the eastern bank, until we were completely plunged in the deep shadow of the vegetation that grew right down to the water's edge, as though he were desirous of escaping observation; at least there was no other reason that I could think of for such a manoeuvre, for by this time the current was running up quite strongly, and under ordinary circumstances it would have been to our advantage to have remained in mid-channel, where the full strength of it would be felt.
