the Unitarian Church, saying that they had a very fine clock in their tower; that they had been so unfortunate as to have their bell broken, and wished to know at what price this bell could be procured.  The agents of the Unitarian Church replied that they had a very fine bell in their tower, and would like to know at what price the Old South Society would sell their clock.  The bell weighs one thousand five hundred and seventy-five pounds; the Boston gentlemen offered one dollar a pound for it, and upon finding they could not get it at any price, they asked where it came from; and having ascertained its history, sent to Lisbon to the same foundry and procured that which they now have.”  And she had been told further that this same bell had been removed to the new church on the Back Bay.  With all this pleasant association with the bell of her own church, of course she must pay it a visit.  So at about nine o’clock, after Mr. Gordon and Tom had gone off with two gentlemen for a day’s blue-fishing, she, with Mrs. Gordon and Bessie, started out for their morning’s sight-seeing.  In a half hour’s time they had climbed the stairs to the tower, and were admiring the fine new clock,—­a gift from one of Nantucket’s sons, now living in New York,—­which had been first set in motion two years before, to replace an old one which had told the time for over half a century.  A little farther up they saw the famous bell, and Miss Ray did wish that she could read Spanish so as to translate the inscription which was upon it.  A few steps more brought them into the dome itself.  Here, then, was the place where “Billy” came to sight the steamers; and here was where a watchman stayed every night to watch for fires.  Whenever he saw one, Bessie said his duty was to hang a lantern upon a hook in the direction of the fire and give the alarm.  She said that this had been the custom for years.  As they were all enjoying this finest view which the island affords, Bessie spied the Old Mill in the distance, and as she had that painted on a shell as a souvenir of her Nantucket trip she must surely visit it.  So they were soon wending their way up Orange street, through Lyons to Pleasant, and then up South Mill to the Old Mill itself.  On paying five cents apiece, they were privileged to go to the top and look through the spy-glass, and also see the miller grind some corn.  This old windmill, built in 1746, with its old oaken beams still strong and sound, situated on a hill by itself, was to Bessie the most picturesque thing that she had seen.  She associated this with the oldest house on the island, built in 1686, facing the south, which she had seen the day before.
