1. In cases where a writ of error is prosecuted to this court, and the judgment of the inferior court is affirmed, the interest shall be calculated and levied, from the date of the judgment below until the same is paid, at the same rate that similar judgments bear interest in the courts of the state where such judgment is rendered.

3. The same rule shall be applied to decrees for the payment of money in cases in equity, unless otherwise ordered by this court.

4. In cases in admiralty, damages and interest may be allowed if specially directed by the court.
