Metes and bounds is a system or method of describing land, real property (in contrast to personal property) or real estate. The system has been used in England for many centuries, and is still used there in the definition of general boundaries. By custom, it was applied in the original Thirteen Colonies that became the United States, and in many other land jurisdictions based on English common law.
Typically the system uses physical features of the local geography, along with directions and distances, to define and describe the boundaries of a parcel of land. The boundaries are described in a running prose style, working around the parcel in sequence, from a point of beginning, returning to the same point; compare with the oral ritual of beating the bounds. It may include references to other adjoining parcels (and their owners), and it, in turn, could also be referred to in later surveys. At the time the description is compiled, it may have been marked on the ground with permanent monuments placed where there were no suitable natural monuments.
A typical description for a small parcel of land would be: "beginning with a corner at the intersection of two stone walls near an apple tree on the north side of Muddy Creek road one mile above the junction of Muddy and Indian Creeks, north for 150 rods to the end of the stone wall bordering the road, then northwest along a line to a large standing rock on the corner of the property now or formerly belonging to John Smith, thence west 150 rods to the corner of a barn near a large oak tree, thence south to Muddy Creek road, thence down the side of the creek road to the starting point."
The sequence begins with an identified corner serving as benchmark. The description then gives distance, direction and various boundary descriptions as if one were walking the bounds pacing off the distance to the next corner where there is a change of direction. Where watercourses form part of the bounds their meander is generally taken as a straight line between the established corners and their monuments.
In many deeds, the direction is described not by azimuth (a clockwise degree measure out of 360 degrees), but instead by bearing (a direction north or south followed by a degree measure out of 90 degrees and another direction west or east). For example, such a bearing might be listed as "N 42°35' W", which means that the bearing is 42°35' counterclockwise, or west of north.
