bar were casting suspicious eyes on them.

Sartan fished around in his pocket and produced a small object in the shape of an irregular triangle. Toryl took the electro-analyzer from him, removed the cover and moved his finger around inside. He replaced the cover and slapped the electro-analyzer against the side of the one-armed bandit. When he took his hand away the small object stuck to the machine like a leech.

Okie scratched his head and addressed one of the two men at the bar. "What the hell you suppose they're doin', Sam? What's that gadget for?"

"Search me," replied Sam, a well dressed, stoop-shouldered gent, "but if you want my opinion it doesn't look legal."

"Hey, Nugget!" yelled the barkeep.

Again the little old prospector hustled himself over to the bar.

"Nugget McDermott at your service! What'll it be, Okie?"

"Go on over and get the sheriff. Tell him there's two queer characters here trying to jimmy one of my machines in broad daylight."

The old man's feet kicked up sawdust as he scampered out the door. Okie kept his attention riveted to the two aliens.

Toryl was busy adjusting the electro-analyzer to the best possible position.

"What if it does not respond to this machine?" Sartan wanted to know.

"I do not think the machine contains any type of metal with which we are unfamiliar. We will have a reading in one minute."

The aliens took a step backward and waited.

A sudden noise, like that of a television tube exploding, jolted everyone in the room, including Toryl and Sartan. The blackjack table emptied. Gamblers left their machines. A semi-circle of the curious formed around the two aliens. Okie lit out from behind the bar and elbowed his way through the crowd.

The aliens' concentration was unbroken by the attention they had aroused. With all the single mindedness of religious fanatics they continued to observe the strange mechanical device.

Okie was dumbfounded to find the machine still in one piece and doubly dumbfounded to discover it was behaving in a most unconventional manner. It was emitting a low steady gurgling sound and an occasional sputter or burp. The legs of the machine seemed unsteady. Its body shifted back and forth in herky-jerky motions like an old-fashioned washing machine. The three little Bell Fruit wheels were spinning at the speed of an airplane propellor. Okie thought they might never stop again.

"What the hell are you crazy galoots doing to my machine!" he bellowed.

Before the aliens could answer there was another explosive sound, causing the crowd to jump back several steps. Quarters fell from the mouth of the machine, slowly at first, then at an alarming rate. The coins fell, bounced and rolled all over the floor. The crowd gulped with fascination.

"Holy catfish!" said one of the men, "how long since that blasted thing's paid off?"

"Looks like this is the first time," said one of the others.

"You guys keep quiet!" yelled Okie.

The coins continued to fall for what seemed like a record time. The crowd was spellbound. Okie watched in silent fury.

And the aliens were more confused than they had been when the machine wasn't paying off.

The one-armed bandit finally coughed out its last quarter. The three Bell Fruit wheels came to an abrupt halt, as though an inner spring had snapped. The machine broke down. Certain observers later reported that the poor thing actually looked exhausted.

The sheriff burst in the door with Nugget McDermott close behind.

"Sheriff, I want you to arrest these two tinhorns!" cried Okie.

"Tinhorns??" Sartan's face was creased with bewilderment.

"What's wrong, Okie?" asked the sheriff.

"Take a look for yourself! These two bugged my machine and then broke it down! Look at that money all over the floor!"

Toryl smiled. "We meant no harm, sir—"

"The hell you didn't mean no harm! You were out to rob me!"

"We
