The plans for the wedding of Miss Alvis Constance and Philipp Edmund Mock have been upset by the European war. The wedding was to have taken place on Aug. 22 at Pocantico Hills, N. Y., at the home of Miss Ehrman's sister, Mrs. William Harrison MacAfee, but the date has been changed to an indefinite time owing to Mr. Mock being in Germany.

Mr. Mock, whose home in in New Haven, Conn., has been unable to get out of Germany. His fiancée, while not alarmed, is anxious for some word of his departure from the scene of the war. Mr. Mock was one of the survivors of the ill-fated Titanic, and is a son of the Baroness von Ploetz of Germany.

Miss Ehrman is the daughter of the late Mr. and Mrs. Rudolph Ehrman and is a kinswoman of Gen. Joseph E. Johnston.
