“Man, we were glad to see each other! Tweel set up a twittering and chirping like a farm in summer and went sailing up and coming down on his beak, and I would have grabbed his hands, only he wouldn’t keep still long enough.
“The other Martians and Leroy just stared, and after a while, Tweel stopped bouncing, and there we were. We couldn’t talk to each other any more than we could before, so after I’d said ‘Tweel’ a couple of times and he’d said ‘Tick,’ we were more or less helpless. However, it was only mid-morning, and it seemed important to learn all we could about Tweel and the city, so I suggested that he guide us around the place if he weren’t busy. I put over the idea by pointing back at the buildings and then at him and us.
“Well, apparently he wasn’t too busy, for he set off with us, leading the way with one of his hundred and fifty-foot nosedives that set Leroy gasping. When we caught up, he said something like ‘one, one, two—two, two, four—no, no—yes, yes—rock—no breet!’ That didn’t seem to mean anything; perhaps he was just letting Leroy know that he could speak English, or perhaps he was merely running over his vocabulary to refresh his memory.
“Anyway, he showed us around. He had a light of sorts in his black pouch, good enough for small rooms, but simply lost in some of the colossal caverns we went through. Nine out of ten buildings meant absolutely nothing to us—just vast empty chambers, full of shadows and rustlings and echoes. I couldn’t imagine their use; they didn’t seem suitable for living quarters, or even for commercial purposes—trade and so forth; they might have been all right as powerhouses, but what could have been the purpose of a whole city full? And where were the remains of the machinery?
“The place was a mystery. Sometimes Tweel would show us through a hall that would have housed an ocean-liner, and he’d seem to swell with pride—and we couldn’t make a damn thing of it! As a display of architectural power, the city was colossal; as anything else it was just nutty!
“But we did see one thing that registered. We came to that same building Leroy and I had entered earlier—the one with the three eyes in it. Well, we were a little shaky about going in there, but Tweel twittered and trilled and kept saying, ‘Yes, yes, yes!’ so we followed him, staring nervously about for the thing that had watched us. However, that hall was just like the others, full of murmurs and slithering noises and shadowy things slipping away into corners. If the three-eyed creature were still there, it must have slunk away with the others.
“Tweel led us along the wall; his light showed a series of little alcoves, and in the first of these we ran into a puzzling thing—a very weird thing. As the light flashed into the alcove, I saw first just an empty space, and then, squatting on the floor, I saw—it! A little creature about as big as a large rat, it was, gray and huddled and evidently startled by our appearance. It had the queerest, most devilish little face!—pointed ears or horns and satanic eyes that seemed to sparkle with a sort of fiendish intelligence.
“Tweel saw it, too, and let out a screech of anger, and the creature rose on two pencil-thin legs and scuttled off with a half-terrified, half defiant squeak. It darted past us into the darkness too quickly even for Tweel, and as it ran, something waved on its body like the fluttering of a cape. Tweel screeched angrily at it and set up a shrill hullabaloo that sounded like genuine rage.
“But the thing was gone, and then I noticed the weirdest of imaginable details. Where it had squatted on the floor was—a book! It had been hunched over a book!
“I took a step forward; sure enough, there was some sort of inscription on the pages—wavy white lines like a seismograph record on black sheets like the material of Tweel’s pouch. Tweel fumed and whistled in wrath, picked up the volume and slammed it into place on a shelf full of others. Leroy and I stared dumbfounded at each other.
“Had the little thing with the fiendish face been reading? Or was it simply eating the pages, getting physical nourishment rather than mental? Or had the whole thing been accidental?
“If the creature were some ratlike pest that destroyed books, Tweel’s rage was understandable, but why should he try to prevent an intelligent being, even though of an alien race, from reading—if it was reading? I don’t know; I did notice that the book was entirely undamaged, nor did I see a damaged book among any that we handled. But I have an odd hunch that if we knew the secret of the little cape-clothed imp, we’d know the mystery of the vast abandoned city and of the decay of Martian culture.
“Well, Tweel quieted down after a while and led us completely around that tremendous hall. It had been a library, I think; at least, there were thousands upon thousands of those queer black-paged volumes printed in wavy lines of white. There were pictures, too, in some; and some of these showed Tweel’s people. That’s a point, of course; it indicated that his race built the city and printed the books. I don’t think the greatest philologist on earth will ever translate one line of those records; they were made by minds too different from ours.
“Tweel could read them, naturally. He twittered off a few lines, and then I took a few of the books, with his permission; he said ‘no, no!’ to some and ‘yes, yes!’ to others. Perhaps he kept
