t margin of the lake.

As they fell the sun struck full upon them, turning their great pinions
into flashing white and silver.

"Oh!" cried the girl, "but they are beautiful!"

Between the house and the lake there was a ridge of rock higher than
the head of a man, and to this Ainsley and his guests ran for cover. On
hands and knees, like hunters stalking game, they scrambled up the face
of the rock and peered cautiously into the pond. Below them, less than
one hundred yards away, on a tiny promontory, the six white birds stood
motionless. They showed no sign of fear. They could not but know that
beyond the lonely circle of the pond were the haunts of men. From
the farm came the tinkle of a cow-bell, the bark of a dog, and in the
valley, six miles distant, rose faintly upon the stillness of the sunset
hour the rumble of a passing train. But if these sounds carried, the
birds gave no heed. In each drooping head and dragging wing, in the
forward stoop of each white body, weighing heavily on the slim, black
legs, was written utter weariness, abject fatigue. To each even to lower
his bill and sip from the cool waters was a supreme effort. And in their
exhaustion so complete was something humanly helpless and pathetic.

To Ainsley the mysterious visitors made a direct appeal. He felt as
though they had thrown themselves upon his hospitality. That they showed
such confidence that the sanctuary would be kept sacred touched him.
And while his friends spoke eagerly, he remained silent, watching the
drooping, ghost-like figures, his eyes filled with pity.

"I have seen birds like those in Florida," Mortimer was whispering, "but
they were not migratory birds."

"And I've seen white cranes in the Adirondacks," said Lowell, "but never
six at one time."

"They're like no bird I ever saw out of a zoo," declared Elsie Mortimer.
"Maybe they ARE from the Zoo? Maybe they escaped from the Bronx?"

"The Bronx is too near," objected Lowell. "These birds have come a great
distance. They move as though they had been flying for many days."

As though the absurdity of his own thought amused him, Mortimer laughed
softly.

"I'll tell you what they DO look like," he said. "They look like that
bird you see on the Nile, the sacred Ibis, they--"

Something between a gasp and a cry startled him into silence. He found
his host staring wildly, his lips parted, his eyes open wide.

"Where?" demanded Ainsley. "Where did you say?" His voice was
