"And so—you're—you're married!" mumbled Mrs. De Peyster.

Jack was too excited by his happiness to have noticed Mrs. De Peyster's voice had it been a dozen-fold more unlike Matilda's than it was. "Yes!" he cried. "And wouldn't it surprise mother if she knew! Mother, sailing so unsuspiciously along on the Plutonia!" He gave a chortle of delight. "But oh, I say, Matilda," he cried suddenly, "you mustn't write her!"

Mrs. De Peyster did not answer.

"We don't want her to know yet," Jack insisted; "that's one reason we've done the whole thing so quietly." Then he added jocosely: "If you tell, there's a thing I might tell her about you. About—u'm—about you and William. Want me to do that—eh? Better promise not to tell."

"I won't," whispered Mrs. De Peyster.

"It's a bargain, then. But there's something else that would surprise her, too. I'm going to work."

"But not at once," put in Mary de Peyster, née Mary Morgan, in her soft contralto voice, that seemed to effervesce with mischief. "Tell Matilda what you're doing to do."

"I've already told you, Matilda, about my little experiment in the pick-and-shovel line. I decided that I didn't care for that profession. I've saved a few hundred out of my allowance. Monday I'm going to enter the School of Mines at Columbia—am going to study straight through the summer—night and day till the money gives out. By that time I ought to be able to get a job that will support us. And then I'll study hard of nights till I become a real mining engineer!"

"But we've got to live close! Oh, but we've got to live close!" exclaimed Mary joyously, as though living close were one of the chiefest pleasures of life.

"Yes, we've certainly got to live close!" emphasized Jack. "That's why we're here."
