It did not take our young people long to make the acquaintance of the real Tom Gray, nor to decide he was a fine fellow and one they could admit to their circle without regret.

"He's like a breath of fresh air," thought Grace, and indeed it was disclosed later that he intended to study forestry because he loved the country and the open air, and spent all his vacations camping out and taking long walking trips. But there was nothing of the gypsy in him. He was full of energy and ambition and infused such a wholesome vigor into whatever he did that the young people felt a new enthusiasm in his presence.

"I propose to celebrate the return of the real Tom Gray," announced Mrs. Gray, "by sending my boys and girls off on a sleighing party this afternoon. The big old sleigh holds exactly eight. Reddy, you may drive, since the roads are so familiar to you. You must all be back at six o'clock, for, remember, to-night we decorate the Christmas tree and every girl freshman in Oakdale High School must have a present on it."

Just after lunch, therefore, after a hard morning's work over Mrs. Gray's "surprise," the young people bundled into the big side-seated sleigh, and tucked the buffalo robes tightly around them. The horses snorted in the crisp, dry air; there was a jingle of merry sleigh bells as off they started down the street toward the open country.

Jingle bells, jingle bells,
Jingle all the way.
Oh, what fun 'tis to ride
In a one-horse open sleigh.

they sang as they bowled over the well-beaten track; and Tom Gray breathed a sigh of pure delight.

"Isn't this great!" he exclaimed. "Wouldn't you rather do this than write an essay or study Latin prose composition?"

"Next to riding in an airship and skating, it's the finest thing I know of," answered David.

"Have you ever ridden in an airship?" demanded Tom.

"No, but I intend to," replied the other; for David had never for a moment relinquished his pet scheme, but worked on his experiments whenever he had a spare moment; little dreaming that one day he was to become the talk of the town.
