Now, when the prince found that he was not likely to leave his father's kingdom again, he sent for his wife, and bade the messenger tell her that he would await her coming in the town on the banks of the great river. This was the reason why he delayed his journey so long, and narrowly escaped being eaten by the crocodile. During the weeks that followed the prince amused himself as best he could, though he counted the minutes to the arrival of the princess, and when she did come, he at once prepared to start for the court. That very night, however, while he was asleep, the princess noticed something strange in one of the corners of the room. It was a dark patch, and seemed, as she looked, to grow longer and longer, and to be moving slowly towards the cushions on which the prince was lying. She shrank in terror, but, slight as was the noise, the thing heard it, and raised its head to listen. Then she saw it was the long flat head of a serpent, and the recollection of the prophecy rushed into her mind. Without waking her husband, she glided out of bed, and taking up a heavy bowl of milk which stood on a table, laid it on the floor in the path of the serpent-for she knew that no serpent in the world can resist milk. She held her breath as the snake drew near, and watched it throw up its head again as if it was smelling something nice, while its forky tongue darted out greedily. At length its eyes fell upon the milk, and in an instant it was lapping it so fast that it was a wonder the creature did not choke, for it never took its head from the bowl as long as a drop was left in it. After that it dropped on the ground and slept heavily. This was what the princess had been waiting for, and catching up her husband's sword, she severed the snake's head from its body.
The morning after this adventure the prince and princess set out for the king's palace, but found when they reached it, that he was already dead. They gave him a magnificent burial, and then the prince had to examine the new laws which had been made in his absence, and do a great deal of business besides, till he grew quite ill from fatigue, and was obliged to go away to one of his palaces on the banks of the river, in order to rest. Here he soon got better, and began to hunt, and to shoot wild duck with his bow; and wherever he went, his dog, now grown very old, went with him.
One morning the prince and his dog were out as usual, and in chasing their game they drew near the bank of the river. The prince was running at full speed after his dog when he almost fell over something that looked like a log of wood, which was lying in his path. To his surprise a voice spoke to him, and he saw that the thing which he had taken for a branch was really a crocodile.
'You cannot escape from me,' it was saying, when he had gathered his senses again. 'I am your fate, and wherever you go, and whatever you do, you will always find me before you. There is only one means of shaking off my power. If you can dig a pit in the dry sand which will remain full of water, my spell will be broken. If not death will come to you speedily. I give you this one chance. Now go.'
The young man walked sadly away, and when he reached the palace he shut himself into his room, and for the rest of the day refused to see anyone, not even his wife. At sunset, however, as no sound could be heard through the door, the princess grew quite frightened, and made such a noise that the prince was forced to draw back the bolt and let her come in. 'How pale you look,' she cried, 'has anything hurt you? Tell me, I pray you, what is the matter, for perhaps I can help!'
So the prince told her the whole story, and of the impossible task given him by the crocodile.
'How can a sand hole remain full of water?' asked he. 'Of course, it will all run through. The crocodile called it a "chance"; but he might as well have dragged me into the river at once. He said truly that I cannot escape him.'
'Oh, if that is all,' cried the princess, 'I can set you free myself, for my fairy godmother taught me to know the use of plants and in the desert not far from here there grows a little four-leaved herb which will keep the water in the pit for a whole year. I will go in search of it at dawn, and you can begin to dig the hole as soon as you like.
To comfort her husband, the princess had spoken lightly and gaily; but she knew very well she had no light task before her. Still, she was full of courage and energy, and determined that, one way or another, her husband should be saved.
It was still starlight when she left the palace on a snow-white donkey, and rode away from the river straight to the west. For some time she could see nothing before her but a flat waste of sand, which became hotter and hotter as the sun rose higher and higher. Then a dreadful thirst seized her and the donkey, but there was no stream to quench it, and if there had been she would hardly have had time to stop, for she still had far to go, and must be back before evening, or else the crocodile might declare that the prince had not fulfilled his conditions. So she spoke cheering words to her donkey, who brayed in reply, and the two pushed steadily on.
Oh! how glad they both were when they caught sight of a tall rock in the distance. They forgot that they were thirsty, and that the sun was hot; and the ground seemed to fly under their feet, till the donkey stopped of its own accord in the cool shadow. But though the donkey might rest the princess could not, for the plant, as she knew, grew on the very top of the rock, and a wide chasm ran round the foot of it. Luckily she had brought a rope with her, and making a noose at one end, she flung it across with all her might. The first time it slid back slowly into the ditch, and she had to draw it up, and throw it again, but at length the noose caught on something, the princess could not see what, and had to trust her whole weight to this little bridge, which might snap and let her fall deep down among the rocks. And in that case her death was as certain as that of the prince.
But nothing so dreadful happened. The princess got safely to the other side, and then became the worst part of her task. As fast as she put her foot on a ledge of the rock the stone broke away from under her, and left her in the same place as before. Meanwhile the hours were passing, and it was nearly noon.
The heart of the poor princess was filled with despair, but she would not give up the struggle. She looked round till she saw a small stone above her which seemed rather stronger than the rest, and by only poising her foot lightly on those that lay between, she managed by a great effort to reach it. In this way, with torn and bleeding hands, she gained the top; but here such a violent wind was blowing that she was almost blinded with dust, and was obliged to throw herself on the ground, and feel about after the precious herb.
For a few terrible moments she thought that the rock was bare, and that her journey had been to no purpose. Feel where she would, there was nothing but grit and stones, when, suddenly, her fingers touched something soft in a crevice. It was a plant, that was clear; but was it the right one? See she could not, for the wind was blowing more fiercely than ever, so she lay where she was and counted the leaves. One, two, three-yes! yes! there were four! And plucking a leaf she held it safe in her hand while she turned, almost stunned by the wind, to go down the rock.
When once she was safely over the side all became still in a moment, and she slid down the rock so fast that it was only a wonder that she did not land in the chasm. However, by good luck, she stopped quite close to her rope bridge and was soon across it. The donkey brayed joyfully at the sight of her, and set off home at his best speed, never seeming to know that the earth under his feet was nearly as hot as the sun above him.
On the bank of the great river he halted, and the princess rushed up to where the prince was standing by the pit he had digged in the dry sand, with a huge water pot beside it. A little way off the crocodile lay blinking in the sun, with his sharp teeth and whity-yellow jaws wide open.
