"That settles it," he mused gloomily. "It is seeping through this ghastly honeycomb somewhere, and it's up to us to get busy with the concrete mixers--and to do it quickly. I can't imagine what Braithwaite was thinking of; to drive this tunnel through one of nature's compost heaps, and then to turn a stream of water through it."
The sun was a fiery globe swinging down to the sky-pitched western horizon when the Kentuckian picked his way out of the dripping caverns. There were two added lines in the frown wrinkling between his eyes, and he was still talking to himself in terms of discouragement. At a conservative estimate three months of time and many thousands of dollars must be spent in lining the spillway tunnel with a steel tube, and in plugging the caverns of the hollow tooth with concrete. And in any one of the ninety days the water might find its increasing way through the "compost heap"; whereupon the devastating end would come swiftly.
It was disheartening from every point of view. Ballard knew nothing of the financial condition of the Arcadia Company, but he guessed shrewdly that Mr. Pelham would be reluctant to put money into work that could not be seen and celebrated with the beating of drums. None the less, for the safety of every future land buyer with holdings below the great dam, the work must be done. Otherwise----
The chief engineer's clean-cut face was still wearing the harassed scowl when Bromley, returning with the excursionists, saw it again.
"The grouch is all yours," said the cheerful one, comfortingly, "and you have a good right and title to it. It's been a hard day for you. Is the arm hurting like sin?"
"No; not more than it has to. But something else is. Listen, Bromley." And he briefed the story of the hollow-tooth promontory for the assistant.
"Great ghosts!--worse and more of it!" was Bromley's comment. Then he added: "I've seen a queer thing, too, Breckenridge: the colonel has moved out, vanished, taken to the hills."
"Out of Castle 'Cadia? You're mistaken. There is absolutely nothing doing at the big house: I've been reconnoitring with the glass."
"No, I didn't mean that," was the qualifying rejoinder. "I mean the ranch outfit down in the Park. It's gone. You know the best grazing at this time of the year is along the river: well, you won't find hair, hoof or horn of the colonel's cattle anywhere in the bottom lands--not a sign of them. Also, the ranch itself is deserted and the corrals are all open."
