One of the advertisements shall be posted in the hundred in which the premises are located, and 1, at least, in each of the hundreds which immediately adjoin the hundred. A like advertisement shall be delivered at least 10 days before the day of sale to the defendant, or left at the defendant’s usual place of abode, if the defendant has a known place of abode in the county; if the defendant does not reside in the county, notice shall be served on the tenant, or if there is no tenant, shall be left at the mansion house or other public place on the premises.

The publishers of the newspapers shall not be paid for such advertising a higher rate than their ordinary charges for transient advertisements.
