 system of metes and bounds
Metes and bounds
Metes and bounds is a system or method of describing land, real 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...

. This system describes property lines based on local markers and bounds drawn by humans, often based on topography. A typical, yet simple, description under this system might read "From the point on the north bank of Muddy Creek one mile (1.6 km) above the junction of Muddy and Indian Creeks, north for 400 yards, then northwest to the large standing rock, west to the large oak tree, south to Muddy Creek, then down the center of the creek to the starting point."

Particularly in New England
New England

, this system was supplemented by drawing town
Town
A town is a human settlement larger than a village but smaller than a city. The size a settlement must be in order to be called a "town" varies considerably in different parts of the world, so that, for example, many American "small towns" seem to British people to be no more than villages, while...

 plat
Plat
A plat in the U.S. is a map, drawn to scale, showing the divisions of a piece of land. Other English-speaking countries generally call such documents a cadastral map or plan....

s. The metes-and-bounds system was used to describe a town of a generally rectangular shape, 4 to 6 miles (~6 to 10 km) on a side. Within this boundary, a map or plat was maintained that showed all the individual lots or properties.

There are some difficulties with this system:
  • Irregular shapes for properties make for much more complex descriptions.
  • Over time, these descriptions become problematic as trees die or streams move by erosion.
  • It wasn't useful for the large, newly surveyed tracts of land being opened in the west, which were being sold sight unseen to investors.


In addition this system didn't work until there were already people on the ground to maintain records. In the 1783 Treaty of Paris
Treaty of Paris (1783)

. The early surveying, particularly in Ohio, was performed with more speed than care, with the result that many of the oldest townships and sections vary considerably from their prescribed shape and area. Proceeding westward, accuracy became more of a consideration than rapid sale, and the system was simplified by establishing one major north-south line (principal meridian

    : The standard one quarter subdivisions of a section, half section, quarter section, or quarter-quarter section etc.. The section is divided into quadrants designated by the standard compass settings-NE, NW, SE,SW. The nomenclature of a Aliquot may be something like NW¼SW¼ which can be interpreted, reading right to left, as designating first that the property is in the southwest (SW¼) quadrant (160 acres) of a given section. This quadrant is further divided into quarters designated the same way but now applying to the smaller piece--in this case the NW quadrant of the SW quadrant--40 acres. The technique of dividing each piece of a section into successively smaller quadrants allows almost any square piece of property that aligns with a section to be designated. A designation like W½SW¼ would designate the western half of the SW quadrant--80 acres.

    s and National Forests are a large part of the public domain land today. The original public domain included the lands that were turned over to the Federal Government by the original 13 States and the areas acquired from the native Indian tribes or foreign powers. Much of this original land was sold to residents by the Homestead Act of 1862
  • Public lands: Lands in public ownership, owned and controlled by the Federal government. Sometimes used interchangeably with Public domain.
  • Range (Rng, R): The east west horizontal number of townships between the Initial point and the corner of the property being described. Usually combined with the Township designation to give the equivalent rectangular XY coordinates (in 6 mile units) of the township containing the property. A designation like T2SR5W would be interpreted as the township that is 2 township units south of the reference point and 5 township units west.

    : A one-square-mile block of land, containing about 640 acres--slight adjustments may have to be made because of the earth's curvature. There are 36 sections in a given 6x6 mile township. Section numbers are usually assigned by a starting in the upper right as section 1 and then proceeding to the left for 6 sections. The 7th section is below section 6 and the sections are then numbered going to the right then counting back to the left, etc. There are many variations on the way sections are numbered and a map may be needed to find a given section. Sections are subdivided into four 160 acre parts designated NW, NE, SW, SE for the appropriate compass quadrants. Each quarter section may be further subdivided into fourths designated the same way for each 40 acre piece, and these pieces may be further divided into 4ea. 10 acre parts all designated the same way for successively small pieces. A designation NW¼SW¼NW¼ would be land in the NW quarter section, the SW quarter of this smaller unit and then the NW quarter section of this still smaller piece--a description for a specific square 10 acre plot--see Aliquots.

Also, a reference to the vertical number (6 miles on a side) of townships between the reference point and the property being described. Usually combined with the Range to give the equivalent XY coordinates (in 6 mile units) of the township containing the property. A designation like T2SR5W would be interpreted as the township that is 2 township units south of the reference point and 5 township units west.
  • Witness corner: A marker set on a property line, near a corner. The witness corner is used when it is impossible to place a monument in the exact location of a section, quarter, or sixteenth corner.

Summary of objects and data required to be noted during survey

  1. The precise length of every line run, noting all necessary offsets therefrom, with the reason and mode thereof.
  2. The kind and diameter of all "bearing trees”, with the course and distance of the same from their respective comers; and the precise relative position of witness corners to the true corners.
  3. The kinds of materials (earth or stone) of which mounds are constructed—the fact of their being conditioned according to instructions - with the course and distance of the "pits", from the centre of the mound, where necessity exists for deviating from the general rule.
  4. Trees on line. The name, diameter, and distance on line to all trees which it intersects.
  5. Intersections by line of land objects. The distance at which the line first intersects and then leaves every settler's claim and improvement; prairie; river, creek, or other "bottom"; or swamp, marsh, grove, and wind fall, with the course of the same at both points of intersection; also the distances at which you begin to ascend, arrive at the top, begin to descend, and reach the foot of all remarkable hills and ridges, with their courses, and estimated height, in feet, above the level land of the surrounding country, or above the bottom lands, ravines, or waters near which they are situated.
  6. Intersections by line of water objects. All rivers, creeks, and smaller streams of water which the line crosses; the distance on line at the points of intersection, and their widths on line. In cases of navigable streams, their width will be ascertained between the meander corners, as set forth under the proper head.
  7. The land's surface - whether level, rolling, broken, or hilly.
  8. The soil - whether first, second, or third rate.
  9. Timber - the several kinds of timber and undergrowth, in the order in which they predominate.
  10. Bottom lands - to be described as wet or dry, and if subject to inundation, state to what depth.
  11. Springs of water - whether fresh, saline, or mineral, and the course of the stream flowing from them.
  12. Lakes and ponds - describing their banks and giving their height, and also the depth of water, and whether it be pure or stagnant.
  13. Improvements. Towns and villages; Indian towns and wigwams; houses or cabins; fields, or other improvements; sugar tree groves, sugar camps, mill seats, forges, and factories.
  14. Coal banks or beds; peat or turf grounds; minerals and ores; with particular description of the same as to quality and extent, and all diggings therefore; also salt springs and licks. All reliable information you can obtain respecting these objects, whether they be on your immediate line or not, is to appear in the general description to be given at the end of the notes.
  15. Roads and trails, with their directions, whence and whither.
  16. Rapids, cataracts, cascades, or falls of water, with the height of their fall in feet.
  17. Precipices, caves, sink-holes, ravines, stone quarries, ledges of rocks, with the kind of stone they afford.
  18. Natural curiosities, interesting fossils, petrifactions, organic remains, also all ancient works of art, such as mounds, fortifications, embankments, ditches, or objects of like nature.
  19. The variation of the needle must be noted at all points or places on the lines where there is found any material change of variation, and the position of such points must be perfectly identified in the notes.

Survey design and protocol

The surveying of any regional area is a multi-step process. First, two controlling survey lines are established for some relatively large area: a baseline

, which runs east-west and a principal meridian

, which runs north-south (Fig. 1). These two lines pass through, and intersect at, a location known as an initial point. Next, at a defined distance interval, commonly 24 or 30 miles (48.3 km) depending on the year and location, standard parallels are established parallel to the baseline. The meridian, baseline and standard parallels thus established form a lattice upon which all further surveying is then based. Subsequent work divides the land into survey township

s of roughly 36 square miles (~93 km2) or 6 miles (~9.7 km) on each side. This is done by the establishing of township and range lines, which run parallel to the baseline and principal meridian, respectively, at six mile (10 km) intervals. Lastly, townships are subdivided into 36 sections
Section (United States land surveying)
In U.S. land surveying under the Public Land Survey System , a section is an area nominally one square mile, containing , with 36 sections making up one survey township on a rectangular grid....

 of one square mile (640 acres, ~2.6 km2) and 144 quarter-sections of 0.25 square mile (160 acres, ~0.65 km2) each. (See descriptions and figures illustrating the system). The federal government typically surveys only to the quarter-section level; smaller parcels are usually surveyed later by private surveyors if necessary.

The townships and sections are indexed based on the township's position relative to the initial point and the section's location within the designated township. Township, range, and section are abbreviated as T, R, and S, respectively, and cardinal bearings from the initial point by N, S, E, and W, and each principal meridian has its abbreviation. Thus, for example, S13-T1S-R20E MDM refers to: Section 13, Township 1 South, Range 20 East, Mount Diablo Meridian, or the 13th section in the first township south of the baseline and 20th township east of the principal meridian. The sections within a township are numbered boustrophedon

Starting in the northeast corner, sections in the first row (sections 1-6) are numbered east to west, those in the second row (sections 7-12) are numbered west to east, the direction continuing to alternate with each row, until section 36 is reached in the southeast corner.

NOTE: A U.S. Survey Mile differs from the International Mile by a few millimeters. In areas where measuring by chain was not possible, such as variable elevated terrain or terrain with water obstructions, distance was calculated using triangulation

 of property title in the United States.

The intersection of a township line with a range line is called a township corner, of a section line with another section, township or range line a section corner, and a point halfway between two section corners a quarter corner. At each such corner, a corner monument is established to mark the location of the corner on the ground. This monument is the legally binding mark used for setting property lines; it is the culminating work of the entire survey. As with most surveying specifications, those for the corners have changed over time. In the 19th century, the monuments were commonly a rock pile, a wooden post, or a combination of the two. Trees were also sometimes used when available. In the 20th century, steel pipes with caps, supported by mounds of rock, became required (e.g. Fig. 3). Monuments are always witnessed to by the marking of other nearby natural objects on the ground. These witnesses can be trees, rocks, or trenches dug in the ground; the exact locations of the witness objects, and the markings made on them, are recorded in the surveyor's official field notes. Witness trees are commonly referred to as bearing trees, and they are highly important, not just for their legal purposes, but also for their use by ecologists in the estimation of historic forest

ers to destroy corner monuments if they felt the patenting of the land would threaten their residence on it. For this reason, destruction of corner monuments or their witness objects is a federal offense.

Because the grid is flat and the earth is round, adjustments must be made periodically; not all sections can be one square mile nor can all townships be exactly 36 square miles. These adjustments are done within each township by starting the sectional surveys of the township in the southeast corner and moving progressively toward the northwest corner. The northernmost and westernmost tier of sections—11 in all—are allowed to deviate from one square mile, but the other 25 are not. This method accommodates the curvature effects, and also allows for the correction of errors made during the surveying—which were not uncommon—without overly compromising the rectangular nature of the system.

Understanding property descriptions

The description of a particular ten acre parcel of land under this system might be given as NW1/4 SW1/4 SE1/4 SEC 22 T2S R3E.
The elements of such descriptions are interpreted from right to left, so we are describing a plot of land in the township that is the third east of the Range Line (R3E) and the second south of the base line (T2S).
We are also looking at section 22 in that township (refer to the grid above).
Next that section is divided into quarters (160 acres each), and we should be in the SE quarter section.
That section is divided again in quarters (40 acres) and the description calls for the SW quarter.
Last in this description, it is quartered again (into 10 acre plots), as we want the NW quarter.

So, in language, the example plot is the NW quarter of the SW quarter of the SE quarter of section 22 of the township that is the second south of the base line and the third east of the range line.
Some descriptions will use other references such as S½ to refer to the south half of a quarter section.
As an area became settled a township and county name might replace the range and base line numbers, but they can always be traced backwards.

Some western states have only one base line. (Notice that these states have straight line borders to the north or south.) This means that all the townships in the state are either north or south. (The base line for survey of the Kansas and Nebraska territories was the 40th parallel dividing them.) They also typically have only one principal meridian. (For examples, the Kansas
Kansas
Kansas is a US state located in the Midwestern United States. It is named after the Kansas River which flows through it, which in turn was named after the Kansa Native American tribe, which inhabited the area. The tribe's name is often said to mean "people of the wind" or "people of the south...

). In the Maine variant of the system, the range line is called the "East Line of State"; all ranges are to the west of this line, and are normally written TxRx WELS, or "West from East Line of State".

 to build rail systems, and millions acres to raise the capital needed to build and maintain the future railways.
Ten square miles of land on each side of the proposed rail track were granted for every one mile of completed railway. The U.S. Public Land Survey System was utilized for measurement. Every one-mile railway completed was akin to a section. If the railway ran predominantly east and west, a 10 miles (16.1 km) range of one square mile sections were allotted on each side of the 400 feet (121.9 m) right-of-way. If the railway ran predominantly north and south, a 10 miles (16.1 km) township of one square mile sections were allotted on each side of the 400 feet (121.9 m) right-of-way. The land was granted in alternating sections (one square mile). Each odd numbered section going to the railroad company. Each even numbered section kept by the government. This created a checkerboard pattern along proposed rail way. This was supposed to guarantee that railroad access would increase the value of not only the railroad granted sections, but also the government owned sections in the checkerboard. The system was devised by Senator Stephen A. Douglas

Education

Under the 1785 act, section 16 of each township was set aside for school purposes, and as such was often called the school section. Section 36 was also subsequently added as a school section in western states. The various states and counties ignored, altered or amended this provision in their own ways, but the general (intended) effect was a guarantee that local schools would have an income and that the community schoolhouses would be centrally located for all children. An example of land allotments made specifically for higher education is Ohio's College Township

Urban design

As roads have typically been laid out along section boundaries spaced one mile (1.6 km) apart, growing urban areas have adopted road grids with mile-long "blocks" as their primary street network. Such roads in urban areas are known as arterials

An arterial road, or arterial thoroughfare, is a high-capacity urban road.
