S.C. Code Ann. § 40-41-210: Itinerant horse trading without license unlawful.

It shall be unlawful for any person to follow the business of horse trading in any of the counties of this State by traveling from place to place without first obtaining from the clerk of the court of the county in which they wish to follow their trade a license permitting them to do so.

The license shall specify the name of the applicant, his former residence and shall be for a period of one year from the issuance thereof. But this section shall not be effective in any county until the governing body of such county authorize, by resolution, the collection of such tax, nor shall it apply to livery or sales stable owners who have a permanent residence within the State.

Any person violating the provisions of this section shall be guilty of a misdemeanor and, upon conviction, shall be punished by a fine of not more than one hundred dollars or imprisonment for not more than thirty days for each and every offense.
