In the rulings of the District Court on the pleadings and admission of evidence we find no reversible error. As the plaintiff’s evidence was uncontradicted, the trial judge properly directed a verdict. On the merits we affirm the judgment, bn the authority of Hill v. American Surety Co., 200 U. S. 197, 26 Sup. Ct. 168, 50 L. Ed. 437, and Title Guarantee & Trust Co. v. Crane Co., 219 U. S. 24, 32, 31 Sup. Ct. 140, 55 L. Ed. 72,
