hen he was a month and two days out of his clay shell, Etl tried to rear up vertically on his tendrils. He kept toppling over. Maybe he was trying to "walk." But there were no bones in those tendrils and, of course, the strong Earth gravity defeated him.

Lots of times I tried to see what he could do. A real scientist would call this "making tests." I just called it fooling around. I made him climb a stool for his food. He seemed to make a careful survey first, eying each rung; then he drew himself up in one motion.

During one of my rare nights in town—to get a refresher from outlandish stuff in Alice's company—I bought some toys. When I came back to relieve Craig, who had taken care of Etl during my absence, I said: "Etl, here's a rubber ball. Let's play."

He caught it on the second try, in those swift, dextrous tendrils. There was a savagery in the way he did it. I thought of a dog snapping a bumblebee out of the air. Yet my idea that Etl was just an animal had almost vanished by then.

I got into the habit of talking to him the way you do to a pup. Sort of crooning. "Good fella, Etl. Smart. You learn fast, don't you?"

Stuff like that. And I'd coax him to climb up the front of my spacesuit. There were fine, barb-like prongs along the length of his many tentacles; I could feel them pulling in the tough, rubberized fabric, like the claws of a climbing kitten. And he would make a kind of contented chirping that might have had affection in it.

But then there was the time when he bit me. I don't know the reason, unless it was that I had held onto his ball too long. He got my finger, through the glove, with his snaggy, chalk-hued mandibles, while he made a thin hissing noise.

Pretty soon my hand swelled up to twice its size, and I felt sick. Klein had to relieve me in the cage for a while. The bite turned out to be mildly venomous. Before that, I'd had a rash on my arms. An allergy, probably; maybe some substance from those Martian plants had gotten inside my spacesuit and rubbed onto my skin. Who knows? Perhaps Earthly flesh can sense alien life, and reddens to fight it off. And there you have one of the potential disadvantages of contact with unknown worlds.
