"Or borrowed an aeroplane. One seems about as possible as the other," grunted Ingred.

"She shall have a photo of the stones at any rate," said Hereward, fingering his camera. "Hurry up and finish, you girls, or the light will be gone!"

"Well, we can't bolt our sandwiches at the rate you do! I wonder you don't choke!"

The old gray stones stood in a circle on the top of the hill, from whence they had possibly seen four thousand summers and winters pass by. Whether their original purpose was temple, astronomical observatory, or both is one of the riddles of antiquarian research, for neolithic man left no record of his doings beyond the weapons buried with him in his barrow. Legend, however, like a busy gossip, had stepped in and supplied points upon which history was silent. Traditions of the neighborhood explained the menhirs as twelve giants turned into stone by the magic powers of good King Arthur, who, in defiance of the claims of the isle of Avalon, was supposed to be buried in a hitherto unexplored chamber of the large green mound that stood near. Sometimes, so the story ran, the giants whispered to one another, and any one who came there alone at daybreak on May morning might glean much useful information regarding the personal appearance of his or her future lover. As it was obviously difficult to reach so out-of-the-way a spot at such a very early hour, the oracles were seldom consulted at the one and only moment when they were supposed to whisper. There were reputed, however, to be other and easier means of gleaning knowledge from them. Ingred, who had been priming herself with local lore, confided details of the occult ceremonial to Quenrede.

"It sounds rather thrillsome!" admitted that damsel doubtfully. "I'd really like to try it, only the boys would tease me to death. You know what they are!"

"They're going over there to photograph the cromlech. You'd have time before they come back."

"Shall I?"

"Go on!"

"Tell me again what to do."

"You let your hair down, and walk bareheaded in and out and in and out round all the circle of stones. Then you put an offering of flowers on that biggest stone—the Giant King, he's called—and throw a pebble into the little pool below. You count the bubbles that come up—one for A, two for B, &c.,—and they'll give you the initial of your future lover. With very great luck, you might see his shadow in the pool, but that does not often happen."
