Had he been a million miles away, I should have known that it was the doctor answering, from his unsurprised and matter-of-fact tone. I imagined I could see the exact expression of his face as he said,—

"After all, then, man is the most perfect animal the Creator could make. From a mechanical standpoint he needs nothing that he has not, and has nothing that he does not need. However you change him, you would make him imperfect. Physiologically he may be much the same on all the planets, but there is room for the widest variations on the intellectual and spiritual side."

"Do not forget that my patriarchal ancestors record that God made man in His own image, upon which there could be no improvement," I put in.

"Yes, but modern scientists would have us believe that your patriarchs would have written a different fable if they had understood the theory of evolution. It appears that man is really a little lower than the angels, by being material and ponderable and visible, but the general image may be the same. Perhaps upon the various planets it may be that the same lines of differences prevail, as between the heathen tribes and the civilized people on earth. There at least we are sure that physiologically no marked difference exists between the lowest savage and the wisest sage."

"Except, perhaps, that the savage may have the best digestion," I added. "Those look as if they had but few troubles and plenty to eat. I see no wrinkles or hard lines. Their forms and features are gracefully rounded. Their eyes are larger and stronger, with a liquid depth suited to this soft and weaker light. None of them wear beards, and very little hair is visible. I must say they do not look at all warlike. If we could only make them understand that we are friendly, I think they would gladly bid us to a feast of freshly-cooked meats and good wines, and ask us, chuckling, for the latest after-dinner stories that are current on Earth."

"Make friendly signs to them, and see how they behave," he suggested.

I slowly waved my hand to them to approach, and extended my arm as if to shake hands. While talking with the doctor I had stood perfectly still, and they had been warily watching me all the time. When I moved and stretched out my arm, they took fright and fled precipitately.

"I have scared them away, as if they were a lot of roe deer!" I exclaimed.

"Then let us hasten preparations while they are gone," he replied. "If you can stand the pressure I have given you, it will be safe to throw off the helmet and suit."

Upon lifting the cover from my head, I caught a draught of fresh cold air that was unspeakably invigorating. I drank it in deep breaths, and felt like skipping about for joy. Kicking off the suit that trammelled me, I put it and the helmet back inside and closed the port-hole. Then the doctor pulled away the bulkhead and breathed the mixed atmosphere, half-Martian from my compartment and half-Earthly from his. He suffered no inconvenience from the sudden half-way step toward a lower density, and presently he emerged into the exhilarating air with me.
