"Listen to this infernal thing!" Altamont raged. "'Wielding a gold-plated spade handled with oak from an original rafter of the Congressional Library, at three-fifteen one afternoon last week—' One afternoon last week!" He cursed luridly. "Why couldn't that blasted magazine say what afternoon? I've gone over a lot of twentieth century copies of that magazine; that expression was a regular cliché with them."
Loudons looked over his shoulder at the photostated magazine page.
"Well, we know it was between June thirteen and nineteen, inclusive," he said. "And there's a picture of the university president, complete with gold-plated spade, breaking ground. Call it Wednesday, the sixteenth. Over there's the tip of the shadow of the old Cathedral of Learning, about a hundred yards away. There are so many inexactitudes that one'll probably cancel out another."
"That's so, and it's also pretty futile getting angry at somebody who's been dead two hundred years, but why couldn't they say Wednesday, or Monday, or Saturday, or whatever?" He checked back in the astronomical handbook, and the photostated pages of the old almanac, and looked over his calculations. "All right, here's the angle of the shadow, and the compass-bearing. I had a look, yesterday, when I was taking the local citizenry on that junket. The old baseball diamond at Forbes Field is plainly visible, and I located the ruins of the Cathedral of Learning from that. Here's the above-sea-level altitude of the top of the tower. After you've landed us, go up to this altitude—use the barometric altimeter, not the radar—and hold position."
Loudons leaned forward from the desk to the contraption Altamont had rigged in the nose of the helicopter—one of the telescope-sighted hunting rifles clamped in a vise, with a compass and a spirit-level under it.
"Rifle's pointing downward at the correct angle now?" he asked. "Good. Then all I have to do is hold the helicopter steady, keep it at the right altitude, level, and pointed in the right direction, and watch through the sight while you move the flag around, and direct you by radio. Why wasn't I born quintuplets?"
"Mr. Altamont! Dr. Loudons!" a voice outside the helicopter called. "Are you ready for us, now?"
Altamont went to the open door and looked out. The old Toon Leader, the Reader, Toon Sarge Hughes, his son, and four young men in buckskins with slung rifles, were standing outside.
"I have decided," the Tenant said, "that Mr. Rawson and Sarge Hughes and I would be of more help than an equal number of younger men. We may not be as active, but we know the old ruins better, especially the paths and hiding places of the Scowrers. These four young men you probably met last evening; it will do no harm to introduce them again. Birdy Edwards; Sholto Jiminez; Jefferson Burns; Murdo Olsen."
