He had bought a large map representing the sea,
Without the least vestige of land:
And the crew were much pleased when they found it to be
A map they could all understand.
What ís the good of Mercatorís North Poles and Equators,
Tropics, Zones, and Meridian Lines?
So the Bellman would cry: and the crew would reply
They are merely conventional signs!
Other maps are such shapes, with their islands and capes!
But we’ve got our brave Captain to thank:
(So the crew would protest) that he has bought us the best
A perfect and absolute blank!
