Some call this the Nile, though many call it Ocean. Those who advocate the Nile point out that it is correctly so called on account of the great length and usefulness of that River, and especially because below the sign is a certain star, shining more brightly than the rest, called Canopus. Canopus is an island washed by the river Nile. (Mary Ward 1960)
