Then Dick turned to the others with a gesture which implied that there was no more to be said, and quietly sat down. _Tenax_ was not the brand that Fuller used, and its different properties would have appeared in the tests. The sub-contractor had betrayed himself by the lie, and his accomplice looked at him with disgust. "You've given the thing away," he growled. "Think they don't know what cement is? Now they have you fixed!" There was silence for the next minute while Stuyvesant studied some figures in his pocket-book. Then he wrote upon a leaf, which he tore out and told Dick to give it to Oliva. "Here's a rough statement of your account up to the end of last month, Don Ramon," he said. "You can check it and afterwards hand the pay-clerk a formal bill, brought up to date, but you'll notice I have charged you with a quantity of cement that's missing from our store. Your engagement with Mr. Fuller ends to-day." Oliva spread out his hands with a dramatic gesture. "Senores, this is a scandal, a grand injustice! You understand it will ruin me? It is impossible that I submit." "Very well. We'll put the matter into the hands of the _Justicia_." "It is equal," Oliva declared with passion. "You have me marked as a thief. The port officials give me no more work and my friends talk. At the _Justicia_ all the world hears my defense." "As you like," said Stuyvesant, but the storekeeper turned to Oliva with a contemptuous grin. "I allow you're not such a blamed fool," he remarked. "Take the chance they've given you and get from under before the roof falls in." Oliva pondered for a few moments, his eyes fixed on Stuyvesant's unmoved face, and then shrugged with an air of injured resignation. "It is a grand scandal, but I make my bill." He moved slowly to the door, but paused as he reached it, and gave Dick a quick, malignant glance. Then he went out and the storekeeper asked Stuyvesant: "What are you going to do with me?" "Fire you right now. Go along to the pay-clerk and give him your time. I don't know if that's all we ought to do; but we'll be satisfied if you and your partner get off this camp." "I'll quit," said the storekeeper, who turned to Dick. "You're a smart kid, but we'd have bluffed you all right if the fool had allowed he used the same cement." Then he followed Oliva, and Stuyvesant got up. "That was Oliva's mistake," he remarked. "I saw where you were leading him and you put the questions well. Now, however, you'll have to take on his duties until we get another man." They left the testing-house, and as Bethune and Dick walked up the valley the former said: "It's my opinion that you were imprudent in one respect. You showed the fellows that it was you who found them out. It might have been better if you had, so to speak, divided the responsibility." "They've gone, and that's the most important thing," Dick rejoined.
