me. The only problem at this point was to get them to move
on after they got their painless dose of sterilizing radiation.

Every tenth "golden boy" was shunted into a small chamber filled with
_orgon_, the instant anaesthetizing gas, and Dr. Sorenson, wearing an
oxygen mask, would catch him as he fell, take his specimen, hand it
through a slot to Dr. Bailey and then drag the unsuspecting victim into
the fresh air where the nurses took over with more wonders to distract
his attention.

This running spot-check on the collected semen samples assured us that
our radiation was effectively destroying the spermatozoa.

I sat at my old place at the base of the ramp, weeding out the
occasional females who tried to sneak in and also checking to see that
we had no repeats.

Our method was simplicity itself. As each native finished our tour an
attendant atomized a faint but very permanent stain of waterproof dye on
the hair of the right shoulder blade. It was hardly noticeable unless
you were looking for it, and that was one of my jobs.

In two days we "toured" 481 males.

A week later the night rains began, and our unwelcomed neighbors
vanished.

Benson had postponed his little lecture deliberately, and now he called
us all together for a fatherly talk which I helped him prepare. He began
abruptly.

"Since nature has been so bountiful in providing us with tala, I don't
intend to proclaim any silly prohibition regarding its consumption. With
a little reflection, however, I hope that all of you can understand that
we must have some control. I am fully aware that many of you arranged
your own private channels for obtaining this liquor, but with the
departure of our tree-climbing friends the easy source has dried up.

"Now, to prevent some of you from breaking your fool necks trying to
climb the trees yourselves, I propose that we place tala in the
commissary as a normal ration to be issued equitably to all--when it is
available. And working together, our clearing parties will, no doubt,
fell enough mango trees to give us all a fair taste."

Benson's unexpected tolerance and remarkable proposal was received with
mixed embarrassment, relief and enthusiasm. He went on, "We have enjoyed
almost two months of rather unrestrained partying, and I'm not going to
rail at you for some of the illicit behaviour that came to my attention.
So far the intimacies which some of you took with the
