Board, a piece of timber sawed thin, for building, and other purposes.

A cheap and durable composi tion for preserving weather board ing, may be made in the following manner :—Take three-parts of slacked lime, two of wood-ashes, and one of fine sand, or sea-coal ashes. Sift these through a fine , and let them be well mis then add as much lintseed oil as will bring the whole into a consistence fit for working with a painter's brush. At first, the weather-boarding a thin coat of this mixture; and when that is dry, give it a second, as thick as can be conveniently worked. This position is cheaper and more durable than paint : it is also impenetrable to water, and Dot liable to be injured by the action of the weather, or the heat of the sun.
