In American land law. A division or parcel of land, on the government survey, comprising one square mile or 640 acres. Each “township” (six miles square) is divided by straight lines into thirty-six sections, and these are again divided into half-sections and quarter-sections. The general and proper acceptation of the terms “section,” “half,” and “quarter section,” as well as their construction by the general land department, denotes the land in the sectional and snbdivisional lines, and not the exact quantity which a perfect admeasurement of an unobstructed surface would declare. Brown v. Hardin, 21 Ark. 327.
