Tips, hints, clues gratefully accepted. Donna, You will find that the base line for the fifth principal meridian runs through Arkansas just below 35 degrees longitude. For a map see <http://www.blm.gov/cadastral/meridians/meridians.htm>. The base line and the fifth principal meridian cross each other at or close to the intersection of Monroe, Phillips, and Lee Counties, Arkansas. I see that Mr. Pence gave you the Bureau of Land Management URL which will be helpful to you. Phil Holm Phil Holm <pholm@rconnect.com>
