The bricks were home made and are smaller than today's standard. The lumber was cut on the premises and hewn no more than necessary. There is no ridge pole, the barked rafters resting against the opposing ones; and plastering of the ceiling on the top floor is simply applied between the beams to what passed for laths, nailed directly to the roof boards with nor furring. We are careful not to jar the ceiling anymore than we can help. And still, although the roof now forms curves for which no equation exists in geometry, and although a marble dropped in one end of the building would probably roll to the other seeking a low spot, and though wondrous systems of leveling are necessary when installing equipment the building is really sound as the day it was built.Colrain mills
