'Tis but a sailor's promise, weather-bound:

"Strike sail, slip cable, here the bark be moored

For once, the awning stretched, the poles assured!

Noontide above; except the wave's crisp dash,

Or buzz of colibri, or tortoise' splash,

The margin's silent: out with every spoil

Made in our tracking, coil by mighty coil,

This serpent of a river to his head

I' the midst! Admire each treasure, as we spread

The bank, to help us tell our history
