girls I collected myself, from de country along de Upper Canal."

I repressed my impulse to show my curiosity. It could all be perfectly true—and if it were not the opening night would tell. But it sounded a lot like one of Dworken's taller tales. I had never been able to disprove any one of them, but I found it a little hard to believe that so many improbable things had ever happened to one man. However, I like being entertained, if it doesn't cost me too much, so finally I said,

"I suppose you are going to tell me you ventured out into the interior of Mars, carrying a six weeks' supply of water and oxygen on your back, and visited the Xo theaters on the spot?"

"How did you know? Dat is just what I did," solemnly affirmed my companion. He snorted again, and looked at his glass. It was empty, but he tilted it into his face again in an eloquent gesture. No words were needed: I punched the symbols for shchikh into the drinkboard on my side of the table. Then, after hesitating, I punched the "two in" signal. I must remember, though, that this was my second and last.

His eighth shchikh seemed to instill some animation into Dworken. "I know you feel skepticality—I mean skepticism—after my exploits. You will see tomorrow night dat I speak true."

"Amazing!" I said. "Especially as I just happen to remember that three different expeditions from Earth tried to penetrate more than a hundred kilometers from Behastin, but either they couldn't carry the water and oxygen that far, or they resorted to breathing Mars air, and never came back. And they were Earthmen, not Venusians who are accustomed to two atmospheres of carbon dioxide."

"My vriend, you must not reason: it was so, it always will be so. The brinciple of induction is long exbloded. I did indeed breathe Mars air. Vait! I tell you how."

He took another long swig of shchikh. "Vat your Eart'men did not realize was dat dey cannot acclimate themselves as do we Venusians. You know de character of our planet made adaptability a condition of survival. It is true dat our atmosphere is heavy, but on top of our so-high mountains de air is t'in. We must live everywhere, de space is so few. I first adapted myself on Eart' to live. I was dere a whole year, you vill recollect. Den I go further. Your engineers construct air tanks dat make like de air of mountains, t'in. So, I learn to live in dose tanks. Each day I haf spent one, two, three hours in dem. I get so I can breathe air at one-third the pressure of your already t'in atmosphere. And at one-sixt' the tension of oxygen. No, my vriend, you could not do this. Your lungs burst. But old Dworken, he has done it.

"I take wit' me only some water, for I know de Martians dey not give water. To trade, some miniature kerosene lamps. You know dey got no fuel oil now, only atomics, but dese little lamps dey like for antiques, for sentiment, because their great-grandfathers used dem.

"Well, I walk through Vlahas, and not stop. Too close by the capital. Too much contact with men of odder planets. I walk also through Bhur and Zamat. I come to a small place where dey never see foreigner. Name Tasaaha. Oh, I tell you, ze men of ze odder planets do not know Mars. How delightful, how unsboiled, are ze Martians, once you get away from de people by tourists so sboiled! How wonderful, across the sands to go, free as birds! The so friendly greetings of de Martian men. And de Martian women! Ah!

"Well, in Tasaaha I go to t'eater. Such lovely girls! You shall see. But I saw somet'ing else. That, my friend, you hardly believe!"

Dworken looked down at his empty glass and snorted gently. I took the hint, although for myself I ordered the less lethal Martian azdzani. I was already having difficulty believing parts of his narrative; it would be interesting to see if the rest were any harder.

My companion continued. "They not only have de chorus, which you haf seen on Earth, imported from Mars—and such a chorus! Such girls! But they
