It would seem that in the survey of this western boundary Governor Miller, through a misconception of his instructions, had caused the line to be run due north, and south, instead of in a direction parallel with that of the east line, as was the evident intention of the treaty of 1817.[313] The effect of this action was to largely curtail the Cherokee frontage on Arkansas River, where the lands were rich and capable of remunerative cultivation, and to extend their frontier on the Upper White River, toward the rough and comparatively valueless region of the Ozark Mountains. It was also admitted by the Secretary of War that the quantity of land within these boundaries was probably less than that to which the Cherokees were entitled.[314] Inquiries were accordingly again made of the several State authorities as to the area of territory acquired by them through the treaties of 1817 and 1819, the replies to which, though partially estimated, aggregated 4,282,216 acres.[315] Directions were therefore given to Agent Duval[316] to propose to the Indians the running of a provisional line, subject to such future alterations as the official returns of the quantity ceded in the States should render necessary and proper. It seems, however, from a report of Agent Duval, that the Cherokees in council had expressed to him a preference to adopt for their western boundary what was known as the "upper" or Governor Miller line, and to run thence down and between the Arkansas and White Rivers for quantity, ignoring the line run under the treaty of 1817 by General Rector, the effect of which would be to give them an extension of territory to the east instead of toward the west. This proposition called forth directions from the Secretary of War to Governor Izard, in the spring of 1825, to open negotiations with the Cherokees upon the subject of an exchange of territory with them for an equal quantity of land lying to the west of Arkansas and Missouri, and for their removal thereto, but that the matter must not be pressed to the point of irritation. If, through the aversion of the Indians to entertain such a proposition, it should be dropped, then, if ±he same should be satisfactory to the citizens of Arkansas, the proposal contained in the report of Agent Duval would meet the views of the Government.[317] The Indians were brought to no definite agreement to either of these propositions. In the meantime their provisional western boundary was established and run, in January and February, 1825.[318] The line began at the upper end of Table Rock Bluff, on the Arkansas River, and ran north 1 mile and 70 chains, crossing Skin Bayou at a distance of 66 chains from the beginning; thence it ran north 53° east 132 miles and 31 chains, to White River, which it struck at a point opposite the mouth of Little North Fork.
