Doctor Dolittle's Post Office
“ They were glad now that the snake had not allowed them to leave the canoe behind. For here, where every step you took you were liable to sink down in the mud up to your waist, Jip and the Doctor would have had hard work to get along at all without it. And, even with it, the going was slow and hard enough. The mangroves spread out long, twisting, crossing arms in every direction to bar your passage—as though they were determined to guard the secrets of this silent, gloomy land where men could not make a home and seldom ever came. ”
