In order to follow the instructions of the doctor I chose the road which followed not the hypotenuse but the two legs of a triangle. Soon I reached the road running along the Green Wall. From beyond the Wall, from the infinite ocean of green there rose toward me an immense wave of roots, branches, flowers, leaves. It rose higher and higher; it seemed as though it would splash over me and that from a man, from the finest and most precise mechanism which I am, I would be transformed into.... But fortunately there was the Green Wall between me and that wild green sea. Oh, how great and divinely limiting is the wisdom of walls and bars! This Green Wall is I think the greatest invention ever conceived. Man ceased to be a wild animal the day he built the first wall; man ceased to be a wild man only on the day when the Green Wall was completed, when by this wall we isolated our machine-like, perfect world from the irrational, ugly world of trees, birds and beasts.... The blunt snout of some unknown beast was to be seen dimly through the glass of the Wall; its yellow eyes kept repeating the same thought which remained incomprehensible to me. We looked into each other's eyes for a long while. Eyes are shafts which lead from the superficial world into a world which is beneath the surface. A thought awoke in me: "what if that yellow-eyed one, sitting there on that absurd dirty heap of leaves, is happier than I, in his life which cannot be calculated in figures!" I waved my hand. The yellow eyes twinkled, moved back and disappeared in the foliage. What a pitiful being! How absurd the idea that he might be happier! Happier than _I_ he may be, but I am an exception, am I not? I am sick. I noticed that I was approaching the dark red walls of the Ancient House and I saw the grown-together lips of the old woman. I ran to her with all speed. "Is she here?" The grown-together lips opened slowly: "Who is 'she'?" "Who? I-330, of course. You remember we came together, she and I, in an aero the other day." "Oh, yes, yes, yes,--yes." Ray-wrinkles around the lips, artful rays radiating from the eyes. They were making their way deeper and deeper into me. "Well, she is here, all right. Came in a while ago." "Here!" I noticed at the feet of the old woman a bush of silver,--bitter wormwood. (The court of the Ancient House, being a part of the museum is carefully kept in its prehistoric state.) A branch of the bush touched the old woman, she caressed that branch; upon her knees lay stripes of sunshine. For a second I myself, the sun, the old woman, the wormwood, those yellow eyes, all seemed to be one; we were firmly united by common veins and one common blood, boisterous, magnificent blood, was running through those veins. I am ashamed now to write down all this, but I promised to be frank to the end of these records: yes, I bent over and kissed that soft, grown-together mouth of the old woman. She wiped it with her hand and laughed.
