“Which?” queried the boy.

“Which what?” said the doctor.

“Which what you said?”

“I did not say anything, sir.”

“Oh my! what a story!” cried the boy, appealing to Helen. “Didn’t you hear him say I was to be his something son?”

“Adopted son,” said the doctor severely; “and, look here, you must not speak to me in that way.”

“All—” Dexter checked himself again, and he only stared.

“Now, you understand,” said the doctor, after a few minutes’ hesitation; “you are to be here like my son, and you may call me—yes, father, or papa.”

“How rum!” said the boy, showing his white teeth with a remarkable want of reverence. “I say,” he added, turning to Helen; “what am I to call you!”

Helen turned to her father for instructions, her brow wrinkling from amusement and vexation.
