The only type of log construction in use in New England in the early days existed in garrison houses built as a protection against the Indians. In every instance the logs were carefully hewed square, to make a close fit against each other, and never notched at the ends, sometimes halved at the corners of the structure, but usually dove-tailed into each other at the ends in medieval military manner. Several of these garrison houses still exist and although afterwards used as dwellings, at first they were built as forts. What happened at the Plymouth Colony after the _Mayflower_ came to anchor? The wind blew very hard for two days and the next day, Saturday, December 23, 1620, as many as could went ashore: "felled and carried timber, to provide themselves stuff for building," and the following Monday "we went on shore, some to fell timber, some to saw, some to rive, and some to carry; so no man rested all that day."[12] Bradford writes "that they builte a forte with good timber" which Isaac de Rasieres described in 1627 as "a large square house, made of thick sawn planks, stayed with oak beams." The oldest existing houses in the Plymouth Colony are built in the same manner and some half dozen or more seventeenth-century plank houses may yet be seen north of Boston. Moreover, when the ship _Fortune_ sailed from Plymouth in the summer of 1621, the larger part of her lading consisted of "clapboards and wainscott," showing clearly that the colonists soon after landing had dug saw pits and produced boards in quantity suitable for the construction of houses and for exportation. [12] _Mourt's Relation_, Boston, 1841. The first settlers in the Massachusetts Bay brought with them mechanics of all kinds, well equipped with tools, and it is altogether probable that these workmen plied their trades on this side of the Atlantic exactly as they had been taught through long centuries of apprenticeship in England. The houses of that early period, still remaining, all resemble similar English structures. Upon arrival, however, the need for shelter was imperative, and all sorts of rude expedients were adopted. Deacon Bartholomew Green, the printer of the _Boston News-Letter_, related that when his father arrived at Boston in 1630, "for lack of housing he was wont to find shelter at night in an empty cask," and during the following winter many of the poorer sort still continued to live in tents through lack of better housing. When Roger Clap arrived at Charlestown in 1630 he "found some Wigwams and one House ... in the meantime before they could build at Boston, they lived many of them in tents and Wigwams."
