The Sea-Serpent

Planché

All bones but yours will rattle when I say
I'm the sea-serpent from America.
Mayhap you've heard that I've been round the world;
I guess I'm round it now, Mister, twice curled.
Of all the monsters through the deep that splash,
I'm "number one" to all immortal smash.
When I lie down and would my length unroll,
There ar'n't half room enough 'twixt pole and pole.
In short, I grow so long that I've a notion
I must be measured soon for a new ocean.
