Evidently there had been three occupants of the craft. But the crash and the fire had almost destroyed their forms. Craig, our biologist, made careful slides of the remains, tagging this as horny epidermis, this as nerve or brain tissue, this as skeletal substance, and this as muscle from a tactile member--the original had been as thin as spaghetti, and dark-blooded. Under the microscope, muscle cells proved to be very long and thin. Nerve cells were large and extremely complex. Yet you could say that Nature, starting from scratch in another place, and working through other and perhaps more numerous millions of years, had arrived at somewhat the same results as it had achieved on Earth. I wonder how an other-world entity, ignorant of humans, would explain a shaving-kit or a lipstick. Probably for like reasons, much of the stuff mashed into that wreck had to remain incomprehensible to us. Wrenches and screwdrivers, however, we could make sense of, even though the grips of those tools were not _hand_-grips. We saw screws and bolts, too. One device we found had been a simple crystal diaphragm with metal details--a radio. There were also queer rifles. Lord knows how many people have wondered what the extraterrestrial equivalents of common human devices would look like. Well, here were some answers. A few of the instruments even had dials with pointers. And the numeral _1_ used on them was a vertical bar, almost like our own. But zero was a plus sign. And they counted by twelves, not tens. But all these parallels with our own culture seemed canceled by the fact that, even when this ship was in its original undamaged state, no man could have gotten inside it. The difficulty was less a matter of human size than of shape and physical behavior. The craft seemed to have been circular, with compartmentation in spiral form, like a chambered nautilus. * * * * * This complete divergence from things we knew sent frost imps racing up and down my spine. And it prompted Blaine to say: "I suppose that emotions, drives, and purposes among off-Earth intelligences must be utterly inconceivable to us." We were assembled in the big trailer that had been brought out for us to live in, while we made a preliminary survey of the wreck. "Only about halfway, Blaine," Miller answered. "Granting that the life-chemistry of those intelligences is the same as ours--the need for food creates the drive of hunger. Awareness of death is balanced by the urge to avoid it. There you have fear and combativeness. And is it so hard to tack on the drives of curiosity, invention, and ambition, especially when you know that these beings made a spaceship? Cast an intelligence in any outward form, anywhere, it ought to come out much the same. Still, there are bound to be wide differences of detail--with wide variations of viewpoint. They could be horrible to us. And most likely it's mutual."
