"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 had somet'ing else."
