Hatley, Miss Greaves, Dr. Baillie, and Mr. Warren; and Mr. Harley was appointed honorary secretary to the Committee, which at its first meeting elected Mr. John Avery as its chairman. After discussing various alternatives the Committee presented a report to the Council on November 30, 1929, in which it made the following suggestions:— 1. That a public meeting should be held on a convenient date early in the New Year; 2.
