Mr. Meredith had read the newspaper accounts of the arrest of Dick Herbert and the seizure of the gold plate and jewels; he had even taunted his charming daughter with it in a fatherly sort of a way. She was weeping, weeping her heart out over this latest proof of the perfidy and loathsomeness of the man she loved. Incidentally, it may be mentioned here that the astute Mr. Meredith was not aware of any elopement plot—either the first or second.

When a card bearing the name of Mr. Augustus S. F. X. Van Dusen was handed to Mr. Meredith he went wonderingly into the reception-room. There was a pause as the scientist and Mr. Meredith mentally sized each other up; then introductions—and The Thinking Machine came down to business abruptly, as always.

"May I ask, Mr. Meredith," he began, "how many sons you have?"

"One," replied Mr. Meredith, puzzled.

"May I ask his present address?" went on the scientist.

Mr. Meredith studied the belligerent eyes of his caller and wondered what business it was of his, for Mr. Meredith was a belligerent sort of a person himself.

"May I ask," he inquired with pronounced emphasis on the personal pronoun, "why you want to know?"

Hatch rubbed his chin thoughtfully. He was wondering what would happen to him when the cyclone struck.

"It may save him and you a great deal of annoyance if you will give me his address," said The Thinking Machine. "I desire to communicate with him immediately on a matter of the utmost importance—a purely personal matter."

"Personal matter?" repeated Mr. Meredith. "Your abruptness and manner, sir, were not calculated to invite confidence."
