The two sat on the grey moonlit grass with the quiet of the night all about them. The great park was still as a painted picture; only the splash of the fountains and the far-off whistle of the Western express broke the silence, which, at the same time, then deepened.
"What cheer, little sister!" said a voice behind them a golden voice. They turned quick, startled heads, as birds, surprised, might turn. There in the moonlight stood Phoebus, dripping still from the lake, and smiling at them, very gentle, very friendly.
"Oh, it's you!" said Kathleen.
"None other," said Phoebus cheerfully. "Who is your friend, the earth-child?"
"This is Mabel," said Kathleen.
Mabel got up and bowed, hesitated, and held out a hand.
"I am your slave, little lady," said Phoebus, enclosing it in marble fingers. "But I fail to understand how you can see us, and why you do not fear."
Mabel held up the hand that wore the ring.
"Quite sufficient explanation," said Phoebus; "but since you have that, why retain your mottled earthy appearance? Become a statue, and swim with us in the lake."
"I can't swim," said Mabel evasively.
