In "A Topographical Description of The Western Territory", p 315, [first published in 1792], Dick's River is described as:
"Dick's River runs through a great body of firft rate land, abounding everywhere with cane, and affords many excellent mill feats. Many mills are already built on this ftream, and will have a plentiful fupply of water in the dryeft feafons. The banks of this river, hear its mouth, are fimilar to the banks of Kentucky. The feveral ftreams and branches of Salt river afford excellent mill feats. Thefe roll themfelves through a great tract of excellent land; but the country from the junction of thefe waters, fome mile above towards the Ohio, which may be about 25 miles, is level and poor, and has abundance of ponds. For a confiderable diftance from the head of this river, the land is of the firft quality, well fituated, and abounds with fine cane. Upon this and Dick's river, the inhabitants are chiefly fettled, it being the fafeft part of the country from the incurfions of the Indians."
[remember "f" = "s" in reading the above quote ] fettled = settled
Mercer County lies to the northwest, and Garrard County to the east. Lincoln county is to the south. Of course, these counties did not exist as part of Kentucky, but as parts of Virginia, when Gilbert Imlay wrote his account of what was considered the "fafeft part of the country".
In 1784, Walker Daniel was instructed to find the "...proper and safe place..." to build a court house and jail for the new "District" of Kentucky. It so happened that Danville was to become this place.
