Land on which said person had paid on by mistake, shall be sold for the taxes and costs, the payment of which, except for mistake, it had escaped, as follows: The chancery clerk shall notify the tax collector of his release of the land first sold and the collector shall immediately give notice in writing to the person in possession of the land paid on by mistake, if any, or to the owner or person claiming it, that at a meeting of the board of supervisors of the county, to be designated in such notice, he will apply for an order to sell said land because of the foregoing facts. At such meeting, the collector shall report the facts in writing to the board of supervisors, and that he has given notice as above required, and said board shall hear any objection to the proposed sale of such land, and unless there be some valid objection shall order it to be sold. Thereupon the collector shall advertise it as sales of land for taxes are required to be advertised, and shall sell it on some day when it is lawful to sell land under execution in his county, and shall proceed in all respects as required in making sales of land for taxes on the first Monday of April. He shall report the lists of lands so sold to the clerk of the chancery court in the same manner and within the same relative time as provided for sales of land for taxes at the usual time. He shall pay over to the proper officers the taxes collected from sales to individuals as in other cases.
