Conduct of sale.
Upon the day of sale, the county superintendent shall make sales by
beginning at the lowest numbered lot and proceeding regularly to the
highest numbered until they are all sold or offered. No lot shall be sold
for less than its valuation. The sale may continue from day to day. Each
lot shall be sold separately and offered long enough to enable any person
present to bid who so desires.
