And of course everyone knows they really don't, which is why they're acceptable.... ] There are times when I don't know my own strength. Or, at least, the strength of my advice. And the case of Jason Howley was certainly an instance of one of those times. When he came to my office with his gadget, I heard him out, trying to appear both interested and co-operative--which is good business. But I am forced to admit that neither Howley nor his gadget were very impressive. He was a lean, slope-shouldered individual, five-feet-eight or nine--which was shorter than he looked--with straight brown hair combed straight back and blue eyes which were shielded with steel-rimmed glasses. The thick, double-concave lenses indicated a degree of myopia that must have bordered on total blindness without glasses, and acute tunnel vision, even with them. He had a crisp, incisive manner that indicated he was either a man who knew what he was doing or a man who was trying to impress me with a ready-made story. I listened to him and looked at his gadget without giving any more indication than necessary of what I really thought. When he was through, I said: "You understand, Mr. Howley that I'm not a patent lawyer; I specialize in criminal law. Now, I can recommend--" But he cut me off. "I understand that, counselor," he said sharply. "Believe me, I have no illusion whatever that this thing is patentable under the present patent system. Even if it were, this gadget is designed to do something that may or may not be illegal, which would make it hazardous to attempt to patent it, I should think. You don't patent new devices for blowing safes or new drugs for doping horses, do you?" "Probably not," I said dryly, "although, as I say, I'm not qualified to give an opinion on patent law. You say that gadget is designed to cause minute, but significant, changes in the velocities of small, moving objects. Just how does that make it illegal?" He frowned a little. "Well, possibly it wouldn't, except here in Nevada. Specifically, it is designed to influence roulette and dice games."
