Enoch did not reply. He stood with bared head while she ran up the steps. Then he reentered the cab and was driven home. But it was not till two weeks later that Enoch sent a note to Diana, asking her to take dinner with him. Even his diary during that period showed no record of his inward flagellations. He did not receive an answer until late in the afternoon. It had been an exceptionally hectic day. Enoch had been summoned before the Senate Committee on appropriations, and with the director of the Reclamation Service had endured a grilling that had had some aspects of the third degree. After some two hours of it the Director had lost his temper. "Gentlemen!" he had cried, "treat me as if I were a common thief, attempting to loot the public funds, if you find satisfaction in it, but at least do not humiliate the Secretary of the Interior in the same manner!" "These people can't humiliate me, Whipple." Enoch had spoken quietly. The blow had struck home and the Senator who was acting as chairman had apologized. Enoch had nodded. "I know! You are in the position of having to appropriate funds for the carrying on of a highly specialized business about which you are utterly ignorant. You are uneasy and you mistake impertinent questioning for keen investigation." "I move we adjourn until to-morrow," a member had said hastily. The motion had carried and Enoch, as though it was already past six o'clock, had started for his office, Whipple accompanying him. "After all this howl over the proposed Paloma Dam," said Whipple, "we may not be able to build it. There's a bunch of Mexicans both this and the other side of the border that have made serious trouble with the preliminary survey, and I have the feeling that there is some power behind that wants to start something." "Is that so?" asked Enoch with interest. "Come in and talk to me a few moments about it." Whipple followed to the Secretary's office. A sealed letter was lying on the desk. Enoch opened it, and read it without ceremony. "Dear Mr. Huntingdon: I find that some old friends are starting for the Grand Canyon this afternoon and they have given me an opportunity to make one of their party. I have been able to arrange my work to Mr. Watkins' satisfaction and so, I'm off. I want to thank you very deeply for the wonderful openings you have made for me and for the very great personal kindness you have shown me. When I return in the winter, I hope I may see you again. "Very sincerely yours, "DIANA ALLEN."
