townships governed by it were surveyed in New Mexico and no disposals based upon those surveys were made. The
Commissioner of the General Land Office, by letter dated July 28, 1936, canceled the Navajo Meridian and the
surveys based on it in the State of New Mexico.
NATIONAL RESERVE – A reservation for naval purposes.
NAVIGABILITY, LEGAL CONCEPT OF – The doctrine laid down by the Supreme Court in The Daniel Ball, 10
Wall. 557 (1871), to wit: “Those rivers must be regarded as public navigable rivers in law which are navigable in
fact. And they are navigable in fact when they are used, or are susceptible of being used, in their ordinary condition,
as highways for commerce, over which trade and travel are or may be conducted in the customary modes of trade or
travel on water.”
NAVIGABLE WATERS – Waters which afford a channel for useful commerce or travel. The beds of navigable
bodies of water are not public domain and are not subject to survey and disposal by the United States. Under the
laws of the United States the navigable waters have always been and shall forever remain common highways. This
includes all tidewater streams and other important permanent bodies of water whose natural and normal condition as
the date of the admission of a State into the Union was such as to classify the same as navigable water.
NEAP TIDES – Tides of decreasing range occurring semimonthly as the result of the moon being in quadrature; that is,
when the tidal forces of sun and moon act at right angles to each other on the waters of the earth. Tides during these
periods do not rise as high or fall as low as during the rest of the month. See TIDE.
NEW MEXICO PRINCIPAL MERIDIAN – The principal meridian governing surveys in New Mexico and the
southwestern part of Colorado; it was adopted in 1855.

Germany, a vernier was called a nonius.
NONNATIVE TOWNSITES, ALASKA – The entry of public lands in Alaska for townsite purposes, by such trustee

boundary. The water is the actual (riparian) boundary and the meander line is the representative (nonriparian)
NON RIPARIAN BROKEN BOUNDARY ADJUSTMENT – 1) A mathematical solution for restoring or
determining the position of angle points of record courses by applying a correction to each record course
based proportionately upon the length of the course. 2) The method generally used to mathematically close (balance)
a figure in order to determine area. 3) May be referred to as the “Compass Rule.” See NON RIPARIAN BROKEN
BOUNDARY, BROKEN BOUNDARY ADJUSTMENT, COMPASS RULE and ADJUSTMENT*.
