"Forget that you heard it," said Marietta quietly, and as her father entered the room again she passed him and went out into the garden.
But Zorzi did not even try to forget the name of the man whom Beroviero appeared to have chosen for his daughter. He tried instead, to understand why Marietta wished him not to remember that the name was Jacopo Contarini. He glanced sideways at the girl's figure as she disappeared through the door, and he thoughtfully pushed another piece of wood into the fire. Some day, perhaps before long, she would marry this man who had been mentioned, and then Zorzi would be alone with old Beroviero in the laboratory. He set his teeth, and poked the fire with, an iron rod.
It happened now and then that Marietta did not come to the glass-house. Those days were long, and when night came Zorzi felt as if his heart were turning into a hot stone in his breast, and his sight was dull, and he ached from his work and felt scorched by the heat of the furnace. For he was not very strong of limb, though he was quick with his hands and of a very tenacious nature, able to endure pain as well as weariness when he was determined to finish what he had begun. But while Marietta was in the laboratory, nothing could tire him nor hurt him, nor make him wish that the hours were less long. He thought therefore of what must happen to him if Jacopo Contarini took Marietta away from Murano to live in a palace in Venice, and he determined at least to find out what sort of man this might be who was to receive for his own the only woman in the world for whose sake it would be perfect happiness to be burned with slow fire. He did not mean to do Contarini any harm. Perhaps Marietta already loved the man, and was glad she was to marry him. No one could have told what she felt, even from that one flashing look she had given her father. Zorzi did not try to understand her yet; he only loved her, and she was his master's daughter, and if his master found out his secret it would be a very evil day for him. So he poked the fire with his iron rod, and set his teeth, and said nothing, while old Beroviero moved about the room.
"Zorzi," said the master presently, "I meant you to hear what I said to my daughter."
"I heard, sir," answered the young man, rising respectfully, and waiting for more.
"Remember the name you heard," said Beroviero.
If the matter had been any other in the world, Zorzi would have smiled at the master's words, because they bade him do just what Marietta had forbidden. The one said "forget," the other "remember." For the first time in his life Zorzi found it easier to obey his lady's father than herself. He bent his head respectfully.
"I trust you, Zorzi," continued Beroviero, slowly mixing some materials in a little wooden trough on the table. "I trust you, because I must trust some one in order to have a safe means of communicating with Casa Contarini."
Again Zorzi bent his head, but still he said nothing.
"These five years you have worked with me in private," the old man went on, "and I know that you have not told what you have seen me do, though there are many who would pay you good money to know what I have been about."
