 A modern example of boustrophedonics is the numbering scheme of sections within survey townships in the United States and Canada.In both countries, survey townships are divided into a 6-by-6 grid of 36 sections.In the U.S. Public Land Survey System, Section 1 of a township is in the northeast corner, and the numbering proceeds boustrophedonically until Section 36 is reached in the southeast corner.
