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

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

"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.
