When the judgment shall be against the house, building, structure, or fixture and land, or against the same without the land, or against a railroad, or railroad embankment, a special writ of execution shall issue, to make the amount recovered by sale of the property, which shall be described therein; and when both a general and special judgment shall be given, both writs may be issued, either separately or combined in one, or one may be issued after the return of the other for the whole or the residue, as the case may require.
