THE OLD WAR machine sat in the village square, its impotent guns pointing aimlessly along the dusty street. Shoulder-high weeds grew rankly about it, poking up through the gaps in the two-yard-wide treads; vines crawled over the high, rust-and guano-streaked flanks. A row of tarnished enameled battle honors gleamed dully across the prow, reflecting the late sun.

A group of men lounged near the machine; they were dressed in heavy work clothes and boots; their hands were large and calloused, their faces weather-burned. They passed a jug from hand to hand, drinking deep. It was the end of a long workday and they were relaxed, good-humored.

“Hey, we’re forgetting old Bobby,” one said. He strolled over and sloshed a little of the raw whiskey over the soot-blackened muzzle of the blast cannon slanting sharply down from the forward turret. The other men laughed.

“How’s it going, Bobby?” the man called.

Deep inside the machine there was a soft chirring sound.

“Very well, thank you,” a faint, whispery voice scraped from a grill below the turret.

“You keeping an eye on things, Bobby?” another man called.

“All clear, the answer came: a bird-chirp from a dinosaur.

“Bobby, you ever get tired just setting here?”

“Hell, Bobby don’t get tired,” the man with the jug said. “He’s got a job to do, old Bobby has.”

“Hey, Bobby, what kind o’boy are you?” a plump, lazy-eyed man called.

“I am a good boy,” Bobby replied obediently.

“Sure Bobby’s a good boy.” The man with the jug reached up to pat the age-darkened curve of chromalloy above him. “Bobby’s looking out for us.”

Heads turned at a sound from across the square: the distant whine of a turbocar, approaching along the forest road.

“Huh! Ain’t the day for the mail,” a man said. They stood in silence, watching as a small, dusty cushion-car emerged from deep shadow into the yellow light of the street. It came slowly along to the plaza, swung left, pulled to a stop beside the boardwalk before a corrugated metal store front lettered BLAUVELT PROVISION COMPANY. The canopy popped open and a man stepped down. He was of medium height, dressed in a plain city-type black coverall. He studied the store front, the street, then turned to look across at the men. He came across toward them.

“Which of you men is Blauvelt?” he asked as he came up. His voice was unhurried, cool. His eyes flicked over the men.

A big, youngish man with a square face and sun-bleached hair lifted his chin.

“Right here,” he said. “Who’re you?”

“Crewe is the name. Disposal Officer, War Materiel Commission.” The newcomer looked up at the great machine looming over them. “Bolo Stupendous, Mark XXV,” he said. He glanced at the men’s faces, fixed on Blauvelt. “We had a report that there was a live Bolo out here. I wonder if you realize what you’re playing with?”
