delivered the opinion of the court.

The judgment in this case is affirmed. No disputed questions of law are involved, and our view’s of the facts are so well expressed in the carefully prepared, opinion of the Court of Claims found in Shipmam v. District of Columbia, 18 C. Cl. 291, that we deem it unnecessary to do more than to refer to that opinion for the reasons of our decision. See Appendix.

Affirmed.
