A one-page broadside dated Boston, January 15, 1752, offering cash premiums to encourage flax production in Massachusetts. Prizes go to the three people who raise the greatest quantities of well-cured and dressed flax, to the best spinners of fine linen thread, and to the weavers of the best linen cloth. It sets out how claims are to be certified and sworn before local officials, and says the Society for Encouraging Industry and Employing the Poor pays the premiums.
