From such a wood, the company emerges into a smoky bottom-land, where shaggy anthracite-colored cattle engage in desultory shoving-matches. They fall in along the course of a rushing river that has vaulted down off the moor. Not far below them, it slows, flattens, and broadens to an estuary. There is the longboat waiting to take Daniel out to Minerva , which is anchored somewhere hereabouts, making ready for the run to Oporto and thence, eventually, to Boston.
