H: What kneading troughs?

D: The mixing vats for the batter. In each one we mix enough batter for a thousand Robots at a time. Next come the vats for livers, brains, etcetera. Then you'll see the bone factory, and after that I'll show you the spinning mill.

H:What spinning mill?

D: The spinning mill for nerves. The spinning mill for veins. The spinning mill where miles and miles of digestive tract are made at once. Then there's the assembly plant where all of this is put together, you know, like automobiles. Each worker is responsible for affixing one part, and then it automatically moves on to a second worker, then to a third, and so on. It's a most fascinating spectacle. Next comes the drying kiln and the stock room where the brand new products are put to work.

H: Good heavens, they have to work immediately?

D: Sorry. They work the same way new furniture works. They get broken in. Somehow they heal up internally or something. Even a lot that's new grows up inside them. You understand, we must leave a bit of room for natural development. And in the meantime the products are refined.

H: How do you mean?
