, the settlers built Fort Frye at Beverly.

The form of the fort was triangular, which is rather uncommon in military defenses. But as they were in a hurry, and it saved them one line of curtains, while the block houses at the angles defended the sides just as well as in any other form, it was adopted. The base of the triangle rested on the river, distant only a few paces from the bank, and was about two hundred feet in length. One of the other sides was somewhat longer, so that the work was not a regular triangle. At each corner, was a two story block house, twenty feet square below, and a foot or two more above. The two longer sides were filled in with dwelling houses, some of which were two stories high, and others of a less hight, while a considerable portion were built barrack fashion, with only one roof, pitched inward, so that the rain from it fell within the garrison. The spaces not occupied by buildings were filled in with stout pickets. Broad, substantial gates, near the northern block house, led out through the palisades into the highway and fields, while a smaller one in the curtain on the bank, called the water gate, afforded an opening to the river. A line of palisades, twelve feet high, at the distance of thirty feet, inclosed the whole, and descended to the river.
