Sorry!

I'm sorry that I have not posted the answer of the riddle.
The answer is a chimney.

A Riddle.

Black within red without,
With four corners round about.
I'll post the answer tomorrow.

Last verse

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I-
I took the one less traveled by,
And that has made all the difference.
ROBERT FROST

Next verse.

And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on way,
I doubted if I should ever come back.
