Mrs. Hilbrough returned with her husband, and Millard explained to her that a certain Baron von Pohlsen, a famous archaeologist, was at that time in Mexico studying the remains of Aztec civilization with the view of enriching the pages of his great work on the "Culturgeschichte" of the ancient Americans. He was to return by way of New York, where his money had been remitted to the Bank of Manhadoes, and he had been socially consigned to Mr. Millard by a friend in Dresden. Pohlsen was obliged to observe some economy in traveling, and had asked Millard to find him a good boarding-house. If Mrs. Hilbrough cared to receive the Baron as a guest for a fortnight, Millard would advise him to accept the invitation, and, as far as possible, would relieve Mr. Hilbrough of his share of the burden by taking the Baron about. This would furnish Mrs. Hilbrough with a good excuse for giving a reception to the nobleman, and then, without any appearance of pushing, she could invite people far afield. It was not in the nature of things that a woman in Mrs. Hilbrough's position should refuse to entertain a baron. She saw many incidental advantages in the plan, not the least of which was that Mr. Millard would be a familiar in the house during the Baron's stay. Hilbrough acquiesced with a rueful sense that he should be clumsy enough at entertaining a foreigner and a man of title. Mrs. Hilbrough thanked Millard heartily for his obliging kindness, but what he cared most for was that Miss Callender's serious face shone with pleasure and gratitude. Having accepted another invitation for the evening, Millard took his leave soon after ten o'clock, proposing to come at a later time to help Mrs. Hilbrough--"and Miss Callender, I hope," he added with a bow to Phillida--to make up the list. Having but two blocks to go, he declined, in favor of Miss Callender, the Hilbrough carriage, which stood ready at the door.
