When one's convinced how things should be
The proper course he can't shun.
His mind made up, he followed it,
Relying on his native wit,
And soon had wandered, bit by bit,
Through all his master's mansion.
"At least," he said: "It's not my fault
If everything's not seen to:
I've gone from garret down to vault,
And glanced into the lean-to.
