ssected for their science, but a
repairman wants to make no sacrifices of any kind for his job. For this
reason, most beacons are built on uninhabited planets. If a beacon _has_
to go on a planet with a culture, it is usually built in some
inaccessible place.

Why this beacon had been built within reach of the local claws, I had
yet to find out. But that would come in time. The first thing to do was
make contact. To make contact, you have to know the local language.

And, for _that_, I had long before worked out a system that was
fool-proof.

I had a pryeye of my own construction. It looked like a piece of rock
about a foot long. Once on the ground, it would never be noticed, though
it was a little disconcerting to see it float by. I located a lizard
town about a thousand kilometers from the pyramid and dropped the eye.
It swished down and landed at night in the bank of the local mud wallow.
This was a favorite spot that drew a good crowd during the day. In the
morning, when the first wallowers arrived, I flipped on the recorder.

After about five of the local days, I had a sea of native conversation
in the memory bank of the machine translator and had tagged a few
expressions. This is fairly easy to do when you have a machine memory to
work with. One of the lizards gargled at another one and the second one
turned around. I tagged this expression with the phrase, "Hey, George!"
and waited my chance to use it. Later the same day, I caught one of them
alone and shouted "Hey, George!" at him. It gurgled out through the
speaker in the local tongue and he turned around.

When you get enough reference phrases like this in the memory bank, the
MT brain takes over and starts filling in the missing pieces. As soon as
the MT could give a running translation of any conversation it heard, I
figured it was time to make a contact.

I found him easily enough. He was the Centaurian version of a
goat-boy--he herded a particularly loathsome form of local life in the
swamps outside the town. I had one of the working eyes dig a cave in an
outcropping of rock and wait for him.

When he passed next day, I whispered into the mike: "Welcome, O
Goat-boy Grandson! This is your grandfather's spirit speaking from
paradise." This fitted in with what I could make out of the local
religion.

Goat-boy stopped as if he'd been shot. Before he could move, I pushed a
switch and a handful of the local cu
