At the same time that Mr. Gordon was exploring the land Mrs. Gordon was in the office of two gallant young civil engineers, exploring the harbor! In fact she was studying a map of the surroundings of the harbor, which these young men had made to aid them in their work of building a jetty from Brant Point to the bell-buoy. As she examined it she found it hard to believe that Nantucket had ever stood next to Boston and Salem, as the third commercial town in the Commonwealth. She sympathized deeply with the people of the years gone by who had been obliged to struggle with such a looking harbor as the map revealed, and said that she should go home to learn more of the "Camels," which she honored more than ever. When they told her that probably three years more than the two that had been given to the work were needed to finish the jetty, and that there was a slight possibility that another one would be needed for the best improvement of the harbor, she thought her interest in the matter could be better kept alive If she should hunt up her old trigonometry and learn that all over again! With this idea she left the young men, whose kindness to her she fully appreciated, and went to find her party. She soon found, on the yacht ready to go back to town, all but Miss Ray; she had chosen to take one of the many carriages which she had noticed were constantly taking passengers back and forth from the town to the Cliff, at the rate of ten cents apiece. Later in the afternoon their attention was arrested by another one of the town-criers,--Tom had learned that there were three in the town,--who was crying out that a meat-auction would be held that night at half-past six o'clock. When they were told that these meat-auctions had been the custom of the town for years, they were anxious to attend one; but another engagement at that hour prevented their so doing, much to Tom's regret.
