ridge is about four times the man’s height. You always find these things on riverbanks and seacoasts, on the two of the seven continents that lie in the temperate zone—and this one’s going to neighbor our own site. The moundbuilders happen to pick all the really good sites. In fact you could just about pick out the sites that are prime for human development by looking for mounds.” (slide) “And this is one of the builders. Caliban is a character in a play: he was big and ugly. That’s what the probe crew called him. Dinosaur’s what you think, isn’t it? Big, gray dinosaur. He’s about four to five meters long, counting tail—warm-blooded, slithers on his belly. Lizard type. But trying to pin old names on new worlds is a pretty hard game. The geologists always have a better time of it than the biologists. They deny it, but it’s true. Look at that skull shape there, that big bulge over the eyes. Now that brain is pretty large, about three times the size of yours and mine. And its convolutions aren’t at all like yours and mine. It’s got a place in the occipital region, the back, that’s like a hard gray handball, and pitted like an old ship’s hull; and then three lobes come off that, two on a side and one on top, shaped like human lungs, and having a common stem and interconnecting stems at several other places along their length. They’re frilled, those lobes—make you think of pink feathers; and then there’s three of those handball-things in the other end of the skull, right up in that place we call the frontal lobes of a human brain, but not quite as big as the organ behind. Now that’s the brain of this citizen of the new world. And if it didn’t connect onto a spinal cord and have branches, and if microscopy didn’t show structure that could answer to neurons, we’d have wondered. It’s a very big brain. We haven’t mapped it enough to know what the correspondences are. But all it does with that big brain is build ridges. Yes, they dissected one…after they established the behavior as instinct-patterned. You do that to a certain extent by frustrating an animal from a goal; and you watch how it goes about the problem. And if the answer is wired into the brain, if it’s instinct and not rationality, it’s going to tend to repeat its behavior over and over again. And that’s what a caliban does. They’re not aggressive. Actually, there’s a smaller, prettier version—” (slide) “The little green fellow with all the collar frills is called an ariel. A-r-i-e-l. That’s Caliban’s elvish friend. Now he’s about a meter long at maximum, nose to tail, and he runs in and out of caliban burrows completely unmolested. They’re fisheaters, both the calibans and ariels, stomachs full of fish. And they’ll nibble fruits. Or investigate about anything you put out for them. None of the lizards are poisonous. None of them ever offered to bite any of the probe team. You do have to watch out for caliban tails, because that’s two meters length of pretty solid muscle, and they’re not too bright, and they just could break your leg for you if they panicked. The ariels can give you a pretty hard swipe too. You pick them up by the base of the tail and the back of the neck, if so happens you have to pick one up, and you hold on tight, because the report is they’re strong. Why would you want to pick one up? Well, not often, I’d think. But they apparently run in and out of caliban burrows, very pretty folk, as you see, and no one’s ever caught an ariel doing a burrow of its own: all play and no work, the ariels. And the probe team found them in their camp, and walking through their tents, and getting into food if they had a chance. They haven’t got any fear at all. They and the calibans sit on top of the food chain, and they haven’t got any competition. The calibans don’t seem to get anything at all out of the association; it’s not certain whether the ariels get anything out of it but
