More on Ellicott's Observatory

This is a second excerpt from The Early History of Gadsden County about Ellicott's Observatory, the little known 1799 scientific camp established on the site of Chattahoochee. The story picks up as Ellicott prepared to leave a similar observatory established in neighboring Jackson County at the point where the Chattahoochee River intersected with the Florida-Alabama line:

The work at the Jackson County camp was completed and the surveyors prepared to drop down the Chattahoochee River to its confluence with the flint when they suddenly received alarming news:

One or two days before we left our position on the Chattahocha for the mouth of Flint river, Mr. Burgess, who had lately been one of our deputy agents, and interpreters, and who had agreeably to the Creek custom intermarried with several of their females, who then lived with him, informed me confidentially, that a plan was laid to plunder us on our way to the St. Mary’s, and requested me to write to Col. Hawkins, to join us at the mouth of Flint river immediately, as his influence would effect our safety, if it was in the power of any man to do it.

The “Mr. Burgess” mentioned by Ellicott was James Burgess, a white trader that lived among the Creeks and maintained trading posts and homes at Tomatley in Jackson County and “Burgess’ Town” on the Flint River (present-day Bainbridge, Georgia). Burgess had lived in the area for more than thirty years and his warning to Ellicott and Minor (who was also now on the scene) was delivered at considerable risk to his own life.

Ellicott wrote a letter to Colonel Hawkins on the night of August 22, 1799, requesting that he join the party at the confluence of the Chattahoochee and Flint Rivers and the next day climbed into a canoe with Minor and paddled downstream to the site of present-day Chattahoochee in Gadsden County. A new camp was established and an astronomical observatory constructed from which the two men could conduct the necessary calculations for running the line east to the head of the St. Mary’s River.

The swampy ground at the mouth of the Flint River proved unsuitable for camping, so Ellicott related that the observatory was established on a nearby bluff:

The ground about the mouth of the Flint river not being fit for encamping on, in consequence thereof, we pitched on the nearest commanding eminence, from which with the least labour in falling the timber, the junction of the rivers might be discovered.

Work had been underway at the Chattahoochee observatory for about two weeks and went peacefully enough for Minor to dismiss his military escort. An escort of American soldiers remained. Things seemed to be going well when James Burgess suddenly appeared on the scene:

On the 9th Mr. Burgess paid us a visit. After dinner he took me into the observatory, and asked this question, “Did you write to Col. Hawkins while at the Upper Camp agreeably to my recommendation”? To which he was answered in the affirmative. “You have not”, says he, “written as pointedly as was necessary, or he would have been here before this: you must write to him immediately, and procure support from the Upper Creeks, which may be had, or you will positively be plundered on your way to St. Mary’s; you may think me a fool, but mark the end.”

Benjamin Hawkins reached the camp at Chattahoochee on September 14th, but just three days later the surveyors received another warning, this time from William Perryman, an important Native American leader that lived about fifteen miles upstream in Jackson County:

Early in the morning of the 17th, we received a message from Indian Willy, (a person of property,) who resides on the Chattahocha, a few miles above the mouth of the Flint river, to the following effect: “Gentleman, I have sent my Negro, to inform you that about twenty Indians lay near my place last night, they intend mischief; many more are behind: they say they are Chocktaws; but this is not true. Be on your guard, and remember I have nothing to do with it: my Negro goes at midnight."

The warnings were providential and caused the surveyors to tighten their guard....

Ellicott's Observatory - A Key Moment in Gadsden County, History

The man seen here is Andrew Ellicott, a contemporary and friend of President George Washington and the man assigned to survey the permanent border between the United States and Spanish Florida.

In 1799 he and his men camped on the present-day site of Chattahoochee, where they conducted astronomical observations to help determine the exact location of the boundary.

The story of Ellicott's Observatory is told in one of the chapters in the new book, The Early History of Gadsden County. If you are interested in obtaining a copy, they can be ordered online by clicking here or from the West Gadsden Historical Society at PO Box D, Greensboro, FL 32330-0803 for $25.00 plus $5 shipping and handling.

Here is the first of a series of excerpts from the Ellicott's Observatory chapter that I will be posting over coming days:

(Excerpt from Chapter Five)

Spain lost control of Florida as a result of the French and Indian War, but regained control of its North American colony in 1783 due to its alliance with the fledgling United States during the American Revolution. Even though they had been allies in the war against Great Britain, however, the two countries soon became uneasy neighbors. Settlers in the southern states looked hungrily to Florida and the Gulf Coast. The old European power found itself faced with an unexpectedly rising American power.

The location of the true border between the two countries became a major issue and following extensive negotiations, the United States and Spain signed the Treaty of San Lorenzo in 1795.

Ratified the following year, the document provided that permanent border between Spanish Florida and the territory of the United States would run east along the 31st parallel to the Chattahoochee River. From the point where the line intersected the river, it would turn south down the center of the Chattahoochee to the tip of the point of land at its confluence with the Flint. From there the line would again turn east and run to the headwaters of the St. Mary’s River, thence down that stream to the Atlantic.

This was all well and good, but neither nation knew exactly where the 31st parallel lay and no one had ever explored the St. Mary’s River sufficiently to find its actual head. As a result it was necessary to employ a joint surveying team to mark the border and establish the line once and for all. The United States designated Andrew Ellicott as its Commissioner of Limits. Spain selected James Dunbar, who was eventually replaced by Stephen Minor.

One of the young nation’s most distinguished surveyors, Ellicott was a native of Maryland and had served during the American Revolution as a major in the Maryland militia. His previous work included the 1786 survey of the western border of Pennsylvania and, of particular note, his 1791 project undertaken at the request of President George Washington to establish the limits for the new District of Columbia. He was one of the men responsible for the unique street design of Washington, D.C.

Spain’s original commissioner, James Dunbar, fell ill before the survey project could begin and was replaced by Captain Stephen Minor of Natchez. A native of Pennsylvania, Minor had served in the Spanish army during the American Revolution and was at the captures of Mobile and Pensacola during that war. A planter, official and commander of the Spanish fort in Natchez, Mississippi, he was a leading figure of his time.

Ellicott and Minor began work on the Mobile River in Alabama in 1799, accompanied by a large team of surveyors, contractors and Spanish troops. The soldiers provided protection for the party against the Creeks, a necessity because the two countries were illegally dividing lands that really belonged to someone else, the Creek Nation. A council was convened with leaders of the Upper Creeks at Pensacola to explain that neither country intended to take any of their lands, but instead were engaged in drawing a line to establish the limits of influence agreed to between the two countries. The Lower Creeks and Seminoles were not represented at the council, but the Spanish governor sent emissaries to them to explain the project.

Ellicott and Minor began the survey by conducting astronomical observations on the Mobile River to determine the exact location where the 31st parallel intersected the river. After erecting a stone at the beginning point for the line, the two commissioners proceeded to Pensacola to enjoy the hospitality of the governor there while the actual work party started chopping its way through the wilderness to mark the line as far east as the Chattahoochee River.

Although neither Ellicott nor Minor knew it at the time, the primitive equipment they used cased them to actually miss their mark. The point where they thought the 31st parallel intersected the Mobile River was actually 799 feet off from the true spot. Over the long distance separating the Mobile and Chattahoochee Rivers, this led to considerable error in marking the line. A study by Greg Spies of Troy University has revealed that the Ellicott Line varies from the true border for virtually its entire length.
