Also visited the same day an ancient garrison-house now occupied by Fred. Ayer, who said it was built one hundred and fifty or one hundred and sixty ago by one Emerson, and that several oxen were killed by lightning while it was building. There was also a pear tree nearly as old as the house. It was built of larger and thicker and harder brick than are used nowadays, and on the whole looked more durable and still likely to stand a hundred years. The hard burnt blue-black ends of some of the bricks were so arranged as to checker the outside. He said it was considered the handsomest house in Haverhill when it was built, and people used to come up from town some two miles to see it. He thought that they were the original doors which we saw. There were but few windows, and most of them were about two feet and a half long and a foot or more wide, only to fire out of. The oven originally projected outside. There were two large fireplaces. I walked into one, by stooping slightly, and looked up at the sky. Ayer said jokingly that some said they were so made to shoot wild geese as they flew over. The chains and hooks were suspended from a wooden bar high in the chimney. The timbers were of immense size.

  Fourteen vessels in or to be in the port of Haverhill, laden with coal, lumber, lime, wood, and so forth. Boys go [to] the wharf with their fourpences to buy a bundle of laths to make a hen-house; none elsewhere to be had.

  Saw two or three other garrison-houses. Mrs. Dustin was an Emerson, one of the family for whom I surveyed.

  Measured a buttonwood tree in Haverhill, one of twenty and more set out about 1739 on the banks of the Merrimack. It was thirteen and eight twelfths feet in circumference at three and a half feet from the ground.
