Old man looks, hesitates, stops. A great emotion comes over him. Hesitates more, goes inside. Finds it, browses it, looks at diagrams. Suddenly stops browsing.
Old man looks at diagram very intently.
His hands tremble. His lips tremble. His eyes become moist. He trembles all over, drops to the floor, book in his hand, opened at diagram. Man in white hunched over old man, shakes head, places sheet over face.
