1. Whenever a special tax is so ordered, and the county commission states in the order that the petitioners desire that the cost of the improvement be payable in one installment, the clerk of the county commission shall make out a separate special tax bill against each tract of land in the district for the amount so assessable against it. Each of such special tax bills shall be in favor of such road district, shall be numbered, and shall state the date of the order of the county commission pursuant to which the improvement is to be made, and describe the tract of land against which it is issued and state the amount so assessed against such tract of land, and shall be signed by the president or vice president of the district and be attested by the clerk of the county commission.

2. The clerk of the county commission shall procure and keep a suitable record book and record therein an abstract or description of each of said special tax bills, and shall deposit such special tax bills with the county treasurer, and cause notice to be given by one publication in a newspaper published in the county that special tax bills in favor of said road district have been issued pursuant to an order of the county commission, giving the date of such order, and delivered to the county treasurer to whom payment thereof may be made. Each of such special tax bills shall constitute a lien upon the land described therein, for the amount thereof and such interest as may accrue thereon, and all costs in collecting the same, including reasonable attorney’s fee to be fixed by the county commission and taxed as costs in the action brought to enforce payment; which lien will be paramount to all other liens except of the state for general state, county, school and road taxes. Each of such special tax bills as are not paid at the expiration of thirty days after the date of such order, shall thereafter bear interest at the rate of eight percent per annum.

3. The county treasurer shall receive payments of such special tax bills and keep a record of each payment and of the name of the party making same, and shall cancel such special tax bills as they are paid, and shall give such district credit for the amount of each payment to him on a special account kept with said district of payments to him on account of such tax bills, indicating therein the amounts paid as principal of such special tax bills and the amount paid as interest. Whenever any of such tax bills has been cancelled by the county treasurer and is exhibited to the clerk of the county commission, or the county treasurer reports payment of any such special tax bills to the clerk of the county commission, he shall note the payment thereof in said record book.

4. If any such special tax bills be unpaid at the expiration of thirty days after the date of such order, the special road district commissioners may borrow money not exceeding the aggregate amount of such special tax bills as are then unpaid, and at a rate of interest not exceeding eight percent per annum, and as such unpaid special tax bills are paid, shall draw warrants on the county treasurer for the amount of such payments, to pay whatever may be so borrowed, with interest thereon; but neither the road district nor the commissioners shall be obligated to pay whatever may be so borrowed, or interest thereon, except out of the collections of such unpaid special tax bills. Money so borrowed shall be deposited with the county treasurer to the credit of such road district.

5. If any such special tax bills be unpaid at the expiration of six months after the date of such order, the commissioners may, and if any are unpaid at the expiration of twelve months after such date, they shall cause suits to be instituted for foreclosure of the lien thereof. Such suits shall be instituted in the circuit court of the county, by any attorney the commissioners may designate and order the county treasurer to deliver such unpaid special tax bills to. The road district shall be plaintiff in such suits and any or all parties having an interest in the property to be affected thereby may be made defendants. In all such suits, each special tax bill shall be prima facie evidence of a valid lien in favor of the district, and upon the land described therein, for the amount stated therein. In all suits, so instituted, there shall be taxed as costs in favor of the attorney instituting the suit, a reasonable attorney’s fee to be fixed by the court.

6. All money collected on special tax bills and all money the special road district commissioners may so borrow, and all interest that may accrue thereon while on deposit in any county depositary, shall be used, and warrants drawn on the treasurer therefor, for the following purposes only: To pay the cost and expense incurred by the special road district commissioners, as found by the county commission, in the preparation of such plans, specifications, estimate, map and profile, and said list of lands, and a reasonable attorney’s fee, as found by the commission, for such petitioners, and to pay the cost of improving said public road or part of a public road in accordance with the plans and specifications so filed with the clerk of the county commission, and such working, administrative and incidental expenses, not otherwise provided for by law, as may be incurred in making such improvement and in procuring, collecting and paying the cost of such improvement, and the balance, if any, shall be used in paying expenses of maintaining such improvement; but if any money should be borrowed by the special road district commissioners, it shall be repaid, with interest thereon, out of the collections of such special tax bills as were unpaid at the time such money was borrowed.
