The jurisdiction of the State has been ceded to the United States over certain land situate in Florence County, near the city of Florence, known as the "National Cemetery." The United States shall retain such jurisdiction so long as such lands shall be used as a national cemetery and no longer. Such jurisdiction is granted on the express condition that this State shall retain a concurrent jurisdiction with the United States in and over such lands, so far as that civil process in all cases not affecting the real or personal property of the United States and such criminal or other process as shall issue under the authority of this State against any person charged with crime or misdemeanor committed within or without the limits of such lands may be executed thereon in the same way and manner as if no jurisdiction had been so ceded.
