He overtook a Crab, who’d paused to gaze

Where stood the Pole. His courteous amaze

Sol’s wrath allays.

Now, even as the Goat was set to guard

The Southern Pole, and visitors retard,

The task of Mr. Crab was just as hard:

The North he barred.

But what’s the use of knock-down argument,

When courtesy will answer your intent?

If with a little tact ’tis wisely blent.
