"Assuming, as I say, that you are not aware of the encroachment," the attorney went on, "the Invisible Company does not desire to let you invite prosecution, but wishes merely to warn you against attempting to put an infringement of their goods on the market. They have plenty of surplus capital, and are prepared to defend their rights with all of it, if necessary. Should you wish to communicate with me or have your counsel do so, my address is on that card," and, leaving the paper of tacks behind him, Mr. Rook left the office. Without taking the trouble to investigate, Lamb knew instinctively that the lawyer was right, an opinion which later inquiry all too thoroughly corroborated. For three years the Invisible Carpet Tack Company had been supplying precisely the article the Universal Company was then striving to perfect. What there was of that trade they had and would keep, and a sickening realization came to the secretary that it meant a total loss to himself and his friends of practically everything they possessed. The machinery in which their money was invested was special machinery that could be used for no other purpose, and was worth but little more than the price of scrap iron. Every cent that they had invested was gone! His first thought was for David Jasper. As for himself, he was young yet. He could stand the loss of five thousand. He could go back to Dorman's, take his old position and be the more valuable for his ripened experience, and there was always a chance that a minor partnership might await him there after a few more years; but as for Jasper, his day was run, his sun had set. It was a hard task that confronted the secretary, but he must do it. He called up Kriegler's and asked for David Jasper, and when David came to the telephone he told him what had happened. Over and over, carefully and point by point, he had to explain it, for his friend could not believe, since he could not even comprehend, the blow that had fallen upon him. Suddenly, Lamb found there was no answer to a question that he asked. He called anxiously again and again. He could hear only a confused murmur in the 'phone. There were tramping feet and excited voices, and he gathered that the receiver was left dangling, that no one held it, that no one listened to what he said. Hastily putting on his coat and hat, he locked the office and took a car for the North Side.
