Rawn had told the truth regarding his resources. He had but one month's salary in his pocket when these final experiments began, and for this money there was just as much need as there ever had been in any other month; for Laura Rawn had quite as much use, at the going scale of living, for one hundred and twenty-five dollars a month now, as she had had for seventy-five dollars a month five years earlier. Yet when Laura Rawn suggested a deferred payment on certain weekly bills, the shopkeepers to whom she had been paying her stipend daily for years demurred sorely. The truth is that the poorest way in the world to establish a credit is to pay bills in cash. Foolishly allow a man to see your cash, and he can see nothing else. Pay him partly in cash, partly in good checks, partly in bad ones, and partly not at all, and he will trust you largely; this being a commercial truth not known of all men, although worth knowing. It may be seen, therefore, that young Halsey's little capital of five hundred dollars was as important as young Halsey's original idea; which latter Mr. Rawn had also appropriated. So now these two bought very considerable bundles of copper wire and other things, and made several machines of this and the other shape, and tried divers experiments which need not be set down here. In all this work young Halsey's manual skill and technical training continually was in quest, John Rawn for the most part standing by and frowning heavily, watching Jacob labor for the earning of Rachel: for Halsey knew this surrender of his idea was the price of Grace. Halsey had little hope of ultimate success in his appliances. Not so Rawn. He had something akin to a feeling of certainty. III Differing thus--yet who shall say they were not partners, after all, since all these things were true regarding them?--they at last emerged from the woodshed in Kelly Row, after many long weeks, whose deeds we need not further chronicle. They carried into the front room of the Rawn house in Kelly Row a small machine, which presently was to do large things; that is to say, to save the self-respect of certain prominent railway men who by this time were convinced that they had been hypnotized to their disadvantage; and also to save the face of John Rawn, although he had not known his face had needed saving.
