The Kentuckian left the porch and went to the edge of the mesa cliff to look down upon the flood, rising now by imperceptible gradations as the enlarging area of the reservoir lake demanded more water. The lapping tide was fully half way up the back wall of the dam, which meant that the colonel's power plant at the mouth of the upper canyon must be submerged past using. Yet the lights were on at Castle 'Cadia.

While he was speculating over this new mystery, the head-lamps of an automobile came in sight on the roundabout road below the dam, and presently a huge tonneau car, well filled, rolled noiselessly over the plank bridge and pointed its goblin eyes up the incline leading to the camp mesa. When it came to a stand at the cliff's edge, Ballard saw that it held Mrs. Van Bryck, Bigelow, and one of the Cantrell girls in the tonneau; and that Elsa was sharing the driving-seat with young Blacklock.

"Good evening, Mr. Ballard," said a voice from the shared half of the driving-seat. And then: "We are trying out the new car—isn't it a beauty?—and we decided to make a neighbourly call. Aren't you delighted to see us? Please say you are, anyway. It is the least you can do."

A CRY IN THE NIGHT

The little French office clock—Bromley's testimonial from his enthusiastic and admiring classmates of the École Polytechnique—had chimed the hour of ten; the August moon rose high in a firmament of infinite depths above the deserted bunk shanties and the silent machinery on the camp mesa; the big touring car, long since cooled from its racing climb over the hills of the roundabout road, cast a grotesque and fore-shortened shadow like that of a dwarfed band-wagon on the stone-chip whiteness of the cutting yard; and still the members of the auto party lingered on the porch of the adobe bungalow.

For Ballard, though he was playing the part of the unprepared host, the prolonged stay of the Castle-'Cadians was an unalloyed joy. When he had established Mrs. Van Bryck in the big easy-chair, reminiscent of Engineer Macpherson and his canny skill with carpenter's tools, and had dragged out the blanket-covered divan for Miss Cantrell and Bigelow, he was free. And freedom, at that moment, meant the privilege of sitting a little apart on the porch step with Elsa Craigmiles.

For the first time in weeks the Kentuckian was able to invite his soul and to think and speak in terms of comfortable unembarrassment. The long strain of the industrial battle was off, and Mr. Pelham's triumphal beating of drums had been accomplished without loss of life, and with no more serious consequences than a lamed arm for the man who was best able to keep his own counsel. Having definitely determined to send in his resignation in the morning, and thus to avoid any possible entanglement which might arise when the instability of the great dam's foundations should become generally known, the burden of responsibility was immeasurably lightened. And to cap the ecstatic climax in its sentimental part, Elsa's mood was not mocking; it was sympathetic to a heart-mellowing degree.

One thing only sounded a jarring note in the soothing theme. That was young Blacklock's very palpable anxiety and restlessness. When the collegian had placed the big car, and had stopped its motor and extinguished its lights, he had betaken himself to the desert of stone chips, rambling therein aimlessly, but never, as Ballard observed, wandering out of eye-reach of the great gray wall of masonry, of the growing lake in the crooking elbow of the canyon, and the path-girted hillside of the opposite shore. Blacklock's too ostentatious time-killing was the latest of the small mysteries; and when the Kentuckian came to earth long enough to remark it, he fancied that Jerry was waiting for a cue of some kind—waiting and quite obviously watching.
