"Hermes, my dear boy, you like my white cows so well that I am going to let you take care of them. I shall not have much time to take care of cows now, for you know I am learning to play upon the lyre."
Hermes took care of the white cows after that, and on summer days he used to drive them across the blue meadows of the sky.
When the Greeks saw the white clouds running before the wind, they would say:
"It is Hermes driving his cows to pasture."
THE RAINBOW BRIDGE
Hermes was so useful that Juno, the queen of the heavens, thought she must have a messenger, too. So she took Iris, a little sky fairy.
Iris lived up among the clouds, and played with the stars, and romped with the little winds.
