In 1845, the Missouri legislators hearkened to oft-repeated pleas from Kentucky and surrendered the remains of the pioneer couple.

Their bones lie now in Frankfort, the capital of the once Dark and Bloody Ground, and in 1880 a monument was raised over them.
To us it seems rather that Kentucky itself is Boone's monument; even as those other great corn States, Illinois and Indiana, are Clark's.

There, these two servants unafraid, who sacrificed without measure in the wintry winds of man's ingratitude, are each year memorialized anew; when the earth in summer--the season when the red man slaughtered--lifts up the full grain in the ear, the life giving corn; and when autumn smiles in golden peace over the stubble fields, where the reaping and binding machines have hummed a nation's harvest song.
