even slept inside the cage, clad in my armor. That's devotion to a purpose for you. In a way, it was like living on a little piece of Mars. Often enough I was bored stiff. But plenty did happen. From the start Etl—we began calling the thing that—showed an almost electrically intense curiosity for everything. Some of the habits of its kind were written in its instincts. It basked in strong light, but it liked dark corners, too. At night—when we turned the sun lamps off, that is—it would bury itself in the dusty soil. Protection against nocturnal cold might have been the reason for that. 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
