From "The Rodent Mariners" by Hamish Maclaren:

We know the ports of all the world
All warehouses, all quays,
All islets, coral-ringed and pearled,
The Blue Hesperides;
And men may search until they die,
And men may blow great fleets sky-high –
But rats alone will hold for aye
The Freedom of the Seas!

Cheerily,
Charley Noble
