1868 Warranty Deed Summary:
From Wikipedia, the free encyclopedia: "A chain is
a unit of length; it measures 66 feet or 22 yards or 100 links. There are
10 chains in a furlong, and 80 chains in one statute mile. An acre is the
area of 10 square chains. The use of the chain was once very common
in laying out townships and mapping the U.S. along the train routes in the
19th century. In the U.S. a federal law was passed in 1785 (the Public Land
Survey Ordinance) that all official government surveys must be done with
a Gunter's chain (also referred to as the "surveyor's chain"). Distances
on township plats made by the U.S. General Land Office are shown in chains."
