A chimney?

That's what. I mean one o' them big ones you see on factories. We have to scrape 'em and paint 'em just like steeples, and that means climbing up the whole length inside. The climbing's easy enough on bolts and braces, but it's something fierce the air you breathe. Why, I've gone up a two-hundred-and-forty-foot chimney with a five-foot opening at the bottom, and found the soot so thick about half-way up--so thick, sir, that I've been almost stuck in it. Yes, sir, just had to shove my head into an eight-inch hole and bore through black stuff, beds of it. And mind, not a hole for air as big as a pin-head from bottom to top.
