But love itself does not argue. At first it is seen far off, like a beautiful bird of rare plumage, among flowers, on a morning in spring; it comes nearer, it is timid, it advances, it recedes, it poises on swiftly beating wings, it soars out of sight, but suddenly it is nearer than before; it changes shapes, and grows vast and terrible, till its flight is like the rushing of the whirlwind; then all is calm again, and in the stillness a sweet voice sings the chant of peace or the melancholy dirge of an endless regret; it is no longer the dove, nor the eagle, nor the storm that leaves ruin in its track—it is everything, it is life, it is the world itself, for ever and time without end, for good or evil, for such happiness as may pass all understanding, if God will, and if not, for undying sorrow.

Zorzi had forgotten his small resentment against Marietta, for not having given him a sign nor sent one word of greeting. He knew only that he loved her with all his heart and would give every hope he had for the pressure of her hand in his and the sound of her answering voice; and he dreaded lest she should pity him, as one pities a hurt creature that one would rather not touch.

It would not be in the hope of seeing her that he might leave the laboratory before long. He felt quite sure that Giovanni would make some further attempt to get possession of the little book that meant fortune to him who should possess it; and Giovanni evidently knew where it was. It would he easy for him to send Zorzi on an errand of importance, as soon as he should be so far recovered as to walk a little. The great glass-houses had dealings with the banks in Venice and with merchants of all countries, and Beroviero had more than once sent Zorzi to Venice on business of moment. Giovanni would come in some morning and declare that he could trust no one but Zorzi to collect certain sums of money in the city, and he would take care that the matter should keep him absent several hours. That would be ample time in which to try the flagstones with a hammer and to turn over the right one. Zorzi had convinced himself that it gave a hollow sound when he tapped it and that Giovanni could find it easily enough.

It was therefore folly to leave the box in its present place any longer, and he cast about in his mind for some safer spot in which to hide it. In the meantime, fearing lest Giovanni might think of sending him out at any moment, he waited till Pasquale had brought him water in the morning, and then raised the stone, as he had done before, took the box out of the earth and hid it in the cool end of the annealing oven, while he replaced the slab. The effort it cost him to move the latter told him plainly enough that his injury had weakened him almost as an illness might have done, but he succeeded in getting the stone into its bed at last. He tapped it with the end of his crutch as he knelt on the floor, and the sound it gave was even more hollow than before. He smiled as he thought how easily Giovanni would find the place, and how grievously disappointed he would be when he realised that it was empty.

It occurred at once to Zorzi that Giovanni's first impression would naturally be that Zorzi had taken the book himself in order to use it during the master's absence; and this thought perplexed him for a time, until he reflected that Giovanni could not accuse him of the deed without accusing himself of having searched for the box, a proceeding which his father would never forgive. Zorzi did not intend to tell the master of his conversation with Giovanni, nor of his suspicions. He would only say that the hiding-place had not seemed safe enough, because the stone gave a hollow sound which even the boys would notice if anything fell upon it.

But for Nella, it would be safest to give the box into Marietta's keeping, since no one could possibly suspect that it could have found its way to her room. At the mere thought, his heart beat fast. It would be a reason for seeing her alone, if he could, and for talking with her. He planned how he would send her a message by Nella, begging that he might speak to her on some urgent business of her father's, and she would come as she had come before; they would talk in the garden, under the plane-tree, where Pasquale and Nella could see them, and he would explain what he wanted. Then he would give her the box. He thought of it with calm delight, as he saw it all in a beautiful vision.

But there was Nella, and there was Pasquale, the former indiscreet, the latter silent but keen-sighted, and quick-witted in spite of his slow and surly ways. Every one knew that the book existed somewhere, and the porter and the serving-woman would guess the truth at once. At present no one but himself knew positively where the thing was. If he carried out his plan, three other persons would possess the knowledge. It was not to be thought of.

He looked about the laboratory. There were the beams and crossbeams, and the box would probably just fit into one of the shadowy interstices between two of the latter. But they were twenty feet from the ground, he had no ladder, and if there had been one at hand he could not have mounted it yet. His eye fell on the big earthen jar, more than half a man's height and as big round as a hogshead, half full of broken glass from the experiments. No one would think of it as a place for hiding anything, and it would not be emptied till it was quite full, several months hence. Besides, no one would dare to empty it without Beroviero's orders, as it contained nothing but fine red glass, which was valuable and only needed melting to be used at once.

It was not an easy matter to take out half the contents, and he was in constant danger of interruption. At night it would have been impossible owing to the presence of the boys. If Pasquale appeared and saw a heap of broken glass on the floor, he would surely suspect something. Zorzi calculated that it would take two hours to remove the fragments with the care necessary to avoid cutting his hands badly, and to put them back again, for the shape of the jar would not admit of his employing even one of the small iron shovels used for filling the crucibles.

With considerable difficulty he moved a large chest, that contained sifted white sand, out of the dark corner in which it stood and placed it diagonally so as to leave a triangular space behind it. To guard against the sound of the broken glass being heard from without, he shut the window, in spite of the heat, and having arranged in the corner one of the sacks used for bringing the cakes of kelp-ashes from Egypt, he began to fill it with the broken glass he brought from the jar in a bucket. When he judged that he had taken out more than half the contents, he took the iron box from the annealing oven. It was hard to carry it under the arm by which he walked with a stick, the other hand being necessary to move the crutch, and as he reached the jar he felt that it was slipping. He bent forward and it fell with a crash, bedding itself in the smashed glass. Zorzi drew a long breath of satisfaction, for the hardest part of the work was done.
