They went out and up the street, moving among the swarming throng. The men in their black clothes bustled about, laughing and talking so gaily that Johannes could not help wondering. He saw how Pluizer nodded to several, but no one returned the greeting; they all looked in front of them as if they did not even see him.
'They go by and laugh now,' said Pluizer, 'as if they none of them knew me. But that is only make-believe. When I am alone with one of them they cannot pretend not to know me, and then they are not so light-hearted.'
And as they went on Johannes was presently aware of some one following them. When he looked round he saw that the tall pale figure was striding on among the people, with long noiseless steps. He nodded to Johannes.
'Do the people see him too?' asked Johannes of Pluizer.
'Certainly, but they do not choose to know him. Well, I pardon them for their arrogance!'
The crowd and the turmoil produced a sort of bewilderment which made Johannes forget his woes. The narrow streets and the high houses, which cut the blue heavens above into straight strips, the people going up and down them, the shuffling of feet and the clatter of vehicles, ousted the visions and dreams of the night, as a storm dissipates the images in a pool of water. It seemed to him that there was nothing in the world but walls, and windows, and men. He felt as if he too must do the same, and rush and push in the seething, breathless whirl.
Presently they came to a quieter neighbourhood, where a large house stood, with plain grey windows. It looked stern and unkindly. Everything was silent within, and Johannes smelt a mixture of sour, unfamiliar odours, with a damp, cellar-like atmosphere for their background. In a room filled with strange-looking instruments sat a lonely man. He was surrounded by books, and glass and copper objects, all unknown to Johannes. A single ray of sunshine fell into the room above his head, and sparkled on flasks full of bright-coloured liquids. The man was gazing fixedly through a copper tube and did not look up.
As Johannes approached he could hear him murmuring, 'Wistik, Wistik!'
By the man's side, on a long black board, lay something white and furry which Johannes could not see very clearly.
'Good-morning, doctor,' said Pluizer; but the doctor did not move.
