Robinetta! Did he still long for her? The more he learnt the feebler that craving became. For that too was dissected, and Pluizer showed him what love really was. Then he felt ashamed, and Doctor Cypher said that he could not as yet express it in numbers, but that he should soon accomplish this. Then things grew darker and darker round little Johannes. He had an obscure feeling of thankfulness that he had not seen Robinetta in the course of that fearful expedition with Pluizer. When he spoke of it to Pluizer he made no reply but a sly laugh; but Johannes understood that this was from no desire to spare him. Those hours which Johannes did not spend in study or work Pluizer took advantage of to show him the life of men. He managed to take him everywhere--into the hospitals where sick people lay in great numbers--long ranks of pale, haggard faces with a dull, suffering expression--and where unearthly silence reigned, broken only by coughing and groaning. And Pluizer showed him how many of them could never leave the place. And when at a fixed hour streams of men and women came pouring into the place to visit their sick relations, Pluizer said: 'You see, they all know that they too must some day find their way into this house and these gloomy rooms, only to be carried out in a black chest.' 'Then how can they ever be so light-hearted?' thought Johannes. And Pluizer took him up to a little attic-room where a dismal twilight reigned, and where the distant tinkle of a piano in a neighbouring house made an incessant dreamy noise. Here they found, among others, one man who lay staring helplessly before him at a narrow sunbeam which slowly crept up the wall. 'He has lain there for seven years,' said Pluizer. 'He was a sailor, and has seen the palms of India, the blue seas of Japan, the forests of Brazil; and now, for seven long years, he has amused himself all day and every day with the sunbeams and the sound of the piano. He will never leave this room again; but it cannot last much longer now.' After this day Johannes had his worst dream; he fancied himself in that little room, listening to the feeble music, in the melancholy half-light, with nothing to look at but the rising and waning sunbeams --never more till the end.
