"Go very gently, good bull," she said, and the animal gave a little leap in the air and came down as lightly as a feather. Then he began a race to that part of the field where the brothers were, and where they had just caught the splendid butterfly. Europa shouted with delight, and how surprised the brothers were to see their sister mounted on the back of a white bull!

They stood with their mouths wide open, not sure whether to be frightened or not. But the bull played round them as gently as a kitten, and Europa looked down all rosy and laughing, and they were quite envious. Then when he turned to take another gallop round the field, Europa waved her hand and called out "Good-by," as if she was off for a journey, and Cadmus, Phoenix, and Cilix shouted "Good-by" all in one breath. They all thought it such good fun.

And then, what do you think happened? The white bull set off as quickly as before, and ran straight down to the seashore. He scampered across the sand, then he took a big leap and plunged right in among the waves. The white spray rose in a shower all over him and Europa, and the poor child screamed with fright. The brothers ran as fast as they could to the edge of the water, but it was too late.

The white bull swam very fast and was soon far away in the wide blue sea, with only his snowy head and tail showing above the water. Poor Europa was holding on with one hand to the ivory horn and stretching the other back towards her dear brothers.

And there stood Cadmus and Phoenix and Cilix looking after her and crying bitterly, until they could no longer see the white head among the waves that sparkled in the sunshine.

Nothing more could be seen of the white bull, and nothing more of their beautiful sister.

This was a sad tale for the three boys to carry back to their parents. King Agenor loved his little girl Europa more than his kingdom or anything else in the world, and when Cadmus came home crying and told how a white bull had carried off his sister, the King was very angry and full of grief.

"You shall never see my face again," he cried, "unless you bring back my little Europa. Begone, and enter my presence no more till you come leading her by the hand;" and his eyes flashed fire and he looked so terribly angry that the poor boys did not even wait for supper, but stole out of the palace wondering where they should go first.

While they were standing at the gate, the Queen came hurrying after them. "Dear children," she said, "I will come with you."

"Oh no, mother," the boys answered, "it is a dark night, and there is no knowing what troubles we may meet with; the blame is ours, and we had better go alone."
