Miss. Code Ann. § 49-5-29

Consent of the State of Mississippi is hereby given to the acquisition by the United States by purchase, lease or gift of such land in Mississippi as in the opinion of the federal government and the governor of the state may be needed for the establishment of national migratory bird refuges in this region. The state shall retain a concurrent jurisdiction with the United States in and over such lands, reserving to the state in a ceded territory full civil and criminal jurisdiction concurrently with the federal government in all violations of the state and federal laws so that civil process in all cases and such criminal process as may issue under the authority of the state against a person charged with the commission of any crime, without or within such jurisdiction, may be executed thereon in like manner as before the passage of this section. Power is hereby conferred on Congress to pass such laws as it may deem necessary to the acquisition as herein provided for incorporation in said national migratory bird refuges of such forest covered or cutover lands lying in Mississippi as, in the opinion of the federal government, may be needed. The power is hereby conferred upon Congress to pass such laws and to make or provide for the making of such rules of both civil and criminal nature, and providing punishment for violation thereof, as in its judgment may be necessary for the management, control, or protection of such land as may from time to time be acquired by the United States under the provisions of this section.
