Upon the erection of Union county, in 1820, the commissioners of Madison ordered the clerk to notify the board of Union county that they were willing to give them two miles and a half off the north end of this county, the line to be run parallel with Root's line. it seems, however, that the line between Madison and Union counties was not established in a satisfactory manner, for it is found that in May, 1823. Patrick McLene, auditor of Madison county, and the auditor of Union, agreed to order out the surveyors to_ establish the line in dispute between these counties. David Chapman was appointed on the part of Madison county, and the following survey was made May 24, and reported by him June 2, 1823:
"To the Auditor of Madison County—Pursuant to your order, to me directed, I attended with Alexander Robison, deputy surveyor of Union county. We proceeded on the 22d inst. to survey the line between the county of Madison and Franklin, from Delaware where the east line of Union county crosses said line; thence south two and a half miles, and made a corner for Union, set a post from which a beech twenty inches in diameter bears N. 20° E., twenty-two links distant; and an elm six inches in diameter, bears S. 32° W., twenty-five links distant; thence west fifteen miles and 298 poles. First mile tree, a white oak twenty-four inches in diameter; crossed Sager's run at one mile and 315 poles; second mile tree, a small hickory; third mile tree, an elm; crossed Darby at three miles and 80 poles; fourth mile tree, a small white oak; crossed road from Sager's mill to London, at four miles and 50 poles; fifth mile tree, a white oak eighteen inches in diameter; sixth mile, a stake in a prairie; seventh mile tree, blazed a tree; then run and measured north two and a half miles, and found the old Delaware and Madison line at that distance, returned to said blazed tree and continued our line west; eighth mile tree, a large burr oak; ninth mile tree, a small jack oak; tenth mile, a hickory stake; road from Mitchell's to London, at ten miles and 70 poles; eleventh mile tree, a white oak; twelfth mile tree, a white oak; crossed Little Darby, at twelve miles and 136 poles running southeast; thirteenth mile tree, a burr oak twenty inches in diameter; crossed Little Darby at thirteen miles and 156 poles running northeast; fourteenth mile tree, a burr oak; fifteenth mile tree, a burr oak; crossed Treacles creek three times at about 160 poles; set a post in the line of Champaign county line, for the northwest corner of Madison county, from which a burr oak fifteen inches in diameter bears north twelve links, and another burr oak fourteen inches in diameter bears S. 85° E., twenty-one links distant."
The line between Madison and Clark counties was still unsettled. On the records, bearing date of June 11, 1824, is found the following: "Ordered by the commissioners of Madison county, that the commissioners of Clark county be notified that they will order their surveyors to attend at the house of John Williams, on Monday, the 5th of July, at 8 o'clock a. m., to run and establish that part of the line between said counties, which is not yet established agreeable to an act of the Legislature passed January 29, 1821." The reader will bear in mind that upon the erection of Clark county in 1817, a portion of Madison was taken in the formation of said county. The town of South Charleston was, previous to the creation of Clark, within the limits of Madison county, as the following record of the plat will demonstrate: "Surveyed for Conrad Critz, the foregoing platted town in Madison county, Stokes township, described as follows: Columbus street runs north 61° east, crossing Chillicothe street at right angles. Chillicothe street runs south 29° east. Given under my hand this 1st day of November, 1815—John T. Stewart." The names of many early settlers of that vicinity may be found in the judicial records of Madison county, as London was then their seat of justice.
The last survey of any boundary line of Madison county which we find on record is the following: "August 23, 1827, surveyed for Madison county, as follows: Beginning at the northeast corner of Canaan township, in the line between the counties of Franklin and Madison, running with said line south one and a half miles, marked a hackberry, sugar and a hickory, for a corner between said counties; thence east two miles, marked a mulberry and a small beech for a corner between said counties (a beech for a mile tree); thence north four miles, and marked a beech for the northeast corner of Madison county, on the north side of the Post road; a small ash for the first mile tree, a sugar tree for the second, a beech for the third mile. David Chapman, surveyor."
