Waldron checked him just in time.
"Enough of this," he interrupted sharply. "I admit, I'm not myself, in this rich atmosphere. I know you're feeling it, already, Flint. Come along out of this, where we can regain our aplomb. We've seen enough, for once."
He turned to Herzog.
"For God's sake, man," cried he, "cork that magic bottle of yours, before all the oxygen-genii escape, or you'll have us both under the table! And, see here," he added, pulling out his check-book, while Flint stared in amazed disgust. "Here, take a blank check." He took his fountain pen and scrawled his name on one. "The amount? That's up to you. Now, let us out," he bade, as Herzog stood there regarding the check with entire uncomprehension. "Out, I say, before I get extravagant!"
Herzog, perfectly comprehending the magnates' unusual conduct as due to oxygen-intoxication in its initial stage, made no comment, but walked to the door, spun the combination and flung it open.
"Glad to have had the pleasure of demonstrating the process to you, gentlemen," said he. "If you're convinced it's practicable, I'm at your orders for any larger extension of the work. Have you any other question or suggestion?"
Neither magnate answered. Flint was trying hard to hold his self-control. Waldron, red-faced now and highly stimulated, looked as though he had been drinking even more than usual.
Both passed out of the laboratory with rather unsteady steps. Together they retraced their way to the administration building; and there, safe at last in the private inner office, with the door locked, they sat down and stared at each other with expressions of amazement.
