These are cross writs of error to a judgment of the District Court of Idaho in a condemnation case. The plaintiffs in error are owners of a tract of 120 acres, which was the object of the suit by the United States. The jury rendered a verdict of $6,250.00 for the plaintiffs, and the court added $328.00 as interest at seven per cent., from the date of the issuing of the summons to that of the judgment. The plaintiffs denied the power of the Congress under the Federal Constitution to condemn the land because not taken for a public use. This entitled them to come to this Court under Â§ 238 of the Judicial Code; and so the United States sued out a cross writ of error to question the legality of including in the judgment the interest item.
