Well, after a while things quieted down. They had to. The police left after sobering up long enough to give me a serious warning against letting such a thing happen again. Mr. Miller, who had come home to see what all the excitement was, went back to work and Mrs. Miller went back to the house and the reporter and photographer drifted off to file their story, or whatever it is they do. Tommy was jubilant. "Did you hear what she said? It'll make the city papers. I wish we had a thousand kites. Ten thousand. Oh boy, selling is fun. Hilary, when can you make some more of that stuff? And Doris, how many mice do you have?" Those mice! I have always kept my enthusiasm for rodents within bounds, but I must admit they were charming little beasts, with tails as bushy as miniature squirrels. "How many generations?" I asked Doris. "Seventeen. No, eighteen, now. Want to see the genetic charts?" I won't try to explain it as she did to me, but it was quite evident that the new mice were breeding true. Presently we asked Betty Miller to come back down to the barn for a conference. She listened and asked questions. At last she said, "Well, all right, if you promise me they can't get out of their cages. But heaven knows what you'll do when fall comes. They won't live in an unheated barn and you can't bring them into the house." "We'll be out of the mouse business by then," Doris predicted. "Every pet shop in the country will have them and they'll be down to nothing apiece." Doris was right, of course, in spite of our efforts to protect the market. Anyhow that ushered in our cage building phase, and for the next week--with a few interruptions--we built cages, hundreds of them, a good many for breeding, but mostly for shipping. It was rather regrettable that, after the _Courier_ gave us most of the third page, including photographs, we rarely had a day without a few visitors. Many of them wanted to buy mice or kites, but Tommy refused to sell any mice at retail and we soon had to disappoint those who wanted kites. The Supermarket took all we had--except a dozen--and at a dollar fifty each. Tommy's ideas of pricing rather frightened me, but he set the value of the mice at ten dollars a pair and got it without any arguments. Our beautiful stationery arrived, and we had some invoice forms printed up in a hurry--not engraved, for a wonder. It was on Tuesday--following the Thursday--that a lanky young man disentangled himself from his car and strolled into the barn. I looked up from the floor where I was tacking squares of screening onto wooden frames. "Hi," he said. "You're Donald Henderson, right? My name is McCord--Jeff McCord--and I work in the Patent Section at the Commission's downtown office. My boss sent me over here, but if he hadn't, I think I'd have come anyway. What are you doing to get patent protection on Ridge Industries' new developments?"
