"I'd like to, Paul," he answered. "But I can't. I've got to rush in a machine all the way to the Buckeye. Word came in just before lunch. They're in trouble at the dam. There must have been a fault in the under-strata, and too-heavy dynamiting has opened it. In short, what's the good of a good dam when the bottom of the reservoir won't hold water?" Three hours later, returning from the Buckeye, Dick noted that for the first time Paula and Graham had gone riding together alone. * * * * * The Wainwrights and the Coghlans, in two machines, out for a week's trip to the Russian River, rested over for a day at the Big House, and were the cause of Paula's taking out the tally-ho for a picnic into the Los Baños Hills. Starting in the morning, it was impossible for Dick to accompany them, although he left Blake in the thick of dictation to go out and see them off. He assured himself that no detail was amiss in the harnessing and hitching, and reseated the party, insisting on Graham coming forward into the box-seat beside Paula. "Just must have a reserve of man's strength alongside of Paula in case of need," Dick explained. "I've known a brake-rod to carry away on a down grade somewhat to the inconvenience of the passengers. Some of them broke their necks. And now, to reassure you, with Paula at the helm, I'll sing you a song: "What can little Paula do? Why, drive a phaeton and two. Can little Paula do no more? Yes, drive a tally-ho and four." All were in laughter as Paula nodded to the grooms to release the horses' heads, took the feel of the four mouths on her hands, and shortened and slipped the reins to adjustment of four horses into the collars and taut on the traces. In the babel of parting gibes to Dick, none of the guests was aware of aught else than a bright morning, the promise of a happy day, and a genial host bidding them a merry going. But Paula, despite the keen exhilaration that should have arisen with the handling of four such horses, was oppressed by a vague sadness in which, somehow, Dick's being left behind figured. Through Graham's mind Dick's merry face had flashed a regret of conscience that, instead of being seated there beside this one woman, he should be on train and steamer fleeing to the other side of the world. But the merriness died on Dick's face the moment he turned on his heel to enter the house. It was a few minutes later than ten when he finished his dictation and Mr. Blake rose to go. He hesitated, then said a trifle apologetically: "You told me, Mr. Forrest, to remind you of the proofs of your Shorthorn book. They wired their second hurry-up yesterday." "I won't be able to tackle it myself," Dick replied. "Will you please correct the typographical, submit the proofs to Mr. Manson for correction of fact--tell him be sure to verify that pedigree of King of Devon--and ship them off."
