Miss. Code Ann. § 65-1-121

A full, complete, and detailed inventory of all property, other than rights of ways and lands containing road building materials, shall be continued as heretofore prepared and filed by the State Highway Department. All of said properties so reported and inventoried and all other property of every kind or description shall be entered in detail and by items in or upon a card index, or other modern filing system, and thereafter all property which may be purchased or acquired by the commission shall be likewise noted and indexed in such filing system so as to keep a complete record of the identity, cost, purpose, use, and location of said property at all times, so that inventory thereof may easily be made; and when disposed of, a complete record of the disposition thereof shall likewise be made. It shall be the duty of each of the highway commissioners and of the director to make a full report annually of all monies or property that have or has come into his possession or control and to faithfully account therefor.
