I turned over my notes again, as one does in such cases, hoping some overlooked solution will leap from the pages.

"I am certain I can do it," I said.

"When? And how much will it cost?"

"That I can't say. It may be tomorrow—it may be next month. The answer perhaps is filtering now in the next room, or it may be a question of several weeks' experiment."

"Not good enough, Ted."

"You told me it would be a year before you expected results."

"A year before we paid dividends. If you can't begin manufacture, how can you expect to make a profit? Your experiments have eaten a deep hole in our resources, and we are where we were at the beginning. In short, Ted, if you don't tell me you are ready to manufacture before the next three months are up, we'll have to close down."

"We might get one of the Germans over and let him have a look at what I'm doing." I went into the next room and came back with a sample. "Here is the stuff—I make it every day in there. But when it goes through in quantity downstairs, I can't get it."

"What are you doing about it?"

"Analyzing all our raw materials to see if I can trace the probable impurity that is blocking us. The apparatus downstairs has been tested and examined a dozen times. I can find nothing the matter there. I thought, at first, lubricating oil might be leaking into the mixers."
