And her hair was not gold.

It was gray, what little there was of it.

No, she ambled a bit, perhaps, where the grass was short and the ground smooth, then she stood still, closed her eyes, and ran and leaped and swayed and darted--with her arms.
Anybody can do it.
At other times she defied gravitation, a secret accomplishment all her own, which she manifested in this wise.

She would begin to jump, higher and higher, and the higher she jumped the lighter she became, until finally she weighed no more than a thistledown, and the effort of leaping became a pure joy and an exhilaration.

Having attained this perfect state of buoyancy, she would set out upon wonderful journeys, springing lightly as far as it pleased her to spring, soaring gracefully over obstacles, and deriving a delirious pleasure from the sensation.
