Texas land survey system
Texas, along with the original thirteen states and several others in the Southwest which were originally deeded with Spanish land grants, does not use the Public Land Survey System. Land grants from the state of Texas to railroad companies were often patented in blocks and sections, and occasionally in units of square miles, officially considered sections.
The Texas Land Survey System is often measured in Spanish Customary Units. The most important of these is the vara, which, while ambiguous in the past, was legally established to be exactly long in June 1919.
The subdivision levels in Texas are as follows:
General subdivisions
- State boundary
- Railroad district
- County
Counties are contained within railroad districts, but township/section, block, and league/labor measurements are not required to follow county boundaries. This is because original measurement lines were drawn before county lines.
Townships and sections (South Texas)
- Township
- Section
Blocks (West Texas)
- Block
- Tract
Tracts, found within blocks, are special categories.
Neither blocks nor tracts obey county lines.
Leagues and labors (North and East Texas)
- League
- Labor
A labor is one million square varas. Therefore, a league is 25 million.
"A league and a labor" was a common first land grant and consisted of a league of land away from the river plus one extra labor of good riparian land. A headright of this much land was granted to "all persons except Africans and their descendants and Indians living in Texas on the day of the declaration of independence." To any single man, 17 years or older, one-third league was granted.
