"Telephone to Gus at the Club that I can't come up to-day. Also send over to the Grand Pacific for a good lunch for two. Have some beer in it--real Munchner, and in _steins_," I directed, and then I reclined on a long leather lounge, and motioned to the doctor to have a chair. He declined, however, and walked slowly back and forth before me as he talked, keeping his right hand inside his coat, and with the left he occasionally ploughed up his heavy hair, as if to ventilate his brain. "A year ago I gave up theoretical physics for applied physics; I resigned my chair at Heidelberg, and came to this progressive city. I brought with me a working model of the greatest invention of this inventive age. Yet it was then neither perfect in design nor complete in detail. But now I have hit on the plan that makes it practicable and certain of success. I need only a little money to build it, and the world will open its eyes!" "But you must pardon me if instead of opening mine I shut them," I interrupted, seeing the point quickly, and losing no time in dodging. "I have no money to invest in patent rights; but still, you must stay to lunch with me." Just here the doctor seemed to find it necessary to diverge from the orderly course of his lecture as he had prepared it, and interject a few impromptu observations. "Events are difficult to forecast, but the capabilities of a youth are harder to divine. One educates his son in all the fine arts, and he turns out a founder of pig iron. One's nephew is apprenticed to a watchmaker, and in a few years, behold, he is a great barrister. Your uncle educated you thoroughly in the old Hebrew and Chaldee of the rabbis, and, lo! you are now the _ursa major_ of the wheat market. "Just now you are in the centre of the kaleidoscope of success. Slater, Bawker & Co. were there a month ago, but now they are only bits of broken glass in the bottom of the heap! And you? you are really a twisted bit of coloured glass like the rest, but you chance to be thrown to the middle. The mirrors of public opinion multiply your importance half a dozen times, and behold you are reflected into the whole picture. But the kaleidoscope turns, and the pieces of glass are shifted. Other broken chips now at the bottom of the heap will soon be filling the centre! "Permit me to change my figure of speech. You are sweeping back the waves of the sea while the tide is falling, and the wide-mouthed public looks on, and whispers about that your broom makes all the waves obey, and drives them back at will. Just when you begin to believe it yourself the tide may turn, and neither brooms nor all the powers on earth can then sweep it back.
