the willows of the brook compass him about;
or the willows of the Nile, as some choose to render it; which would put it out of all doubt that the river horse is intended, if it could be established, it being an inhabitant of that river; and yet the above writer F11 speaks of elephants, when grown old, seeking large thick and shady woods to take up their abode in.
