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."
Enoch folded the note and slipped it into his pocket, then he looked at the waiting Director. "I hope you'll excuse me, Whipple, but this is something to which I must give my personal attention," and without a word further, he put on his hat and walked out of the office. He did not go to his waiting carriage but, leaving the building by another door, he walked quickly to the drug store on the corner and, entering a telephone booth, called the railroad station. The train connecting for the Southwest had left an hour before. Enoch hung up the receiver and walked out to the curb, scowling and striking his walking stick against his trouser leg. Finally he got aboard a trolley.
