“Oh, of course, but, you see, we go as Observers.”
“Ah, now, I understand. You mean you don’t buy anything and so you are able to watch everything?”
“No,” she said, “it’s not that. We do buy things. That’s part of it. Most of the girls like to buy little knick-knacks, and anyway it gives them a good chance to do their shopping while they’re there. But while they are there they are observing. Then afterwards they make charts.”
“Charts of what?” I asked.
“Charts of the employes; they’re used to show the brain movement involved.”
“Do you find much?”
“Well,” she said hesitatingly, “the idea is to reduce all the employes to a Curve.”
“To a Curve?” I exclaimed, “an In or an Out.”
“No, no, not exactly that. Didn’t you use Curves when you were at college?”
“Never,” I said.
