and dining rooms were set up to feed and house the expected influx of seriously ill patients. Due to the threat of crowd contagion and to prevent disturbing patients in the isolation wards, the Exhibition was cancelled that year. In 1920, the Prince of Wales (later Edward VIII) visited the Exhibition, following which the Association moved to incorporate the word "Royal" into its name as the Royal National Agricultural and Industrial Association of Queensland, which over the years has been reduced, unofficially, to the Royal National Association (RNA). In recent years the RNA has registered as its trademark the word "Ekka" (a long-standing colloquial shortening of the word 'Exhibition'). During the interwar years many improvements were made to the exhibition grounds, with various buildings erected or extended during this period. A timber show hall was erected between Gregory Terrace and Water Street and a brick exhibition building, designed by architects Atkinson & Conrad, was constructed in 1923 for Lever Bros of Sydney. In 1922–23, the Ernest Baynes Stand was erected on the site of the 1885 grandstand. Designed by architect Richard Gailey, Junior and constructed by John Hutchinson, the building had two tiers with a seating capacity of 5000 and a total capacity of 7000. It was constructed with a steel frame faced with brick, the larger steel sections being imported from Britain and the smaller sections made in Australia. The foundation stone of the new grandstand was laid by Queensland Governor, Sir Matthew Nathan, in November 1922 and the stand was completed in time for the August 1923 Exhibition, at a cost of . The sub-floor contained a dining room which could accommodate 600 persons at a sitting and a row of ten shops facing the lane at the rear of the structure. A second show ring, intended principally for exhibiting dairy cattle, was established to the north of the Exhibition railway line which transects the Exhibition Grounds and was ready for the show of 1924. Its construction reflected the growing importance of the dairy industry to Queensland where, with Government encouragement, it became Queensland's second largest primary industry and sustained rural Queensland during the depression of the 1930s. By 1925, the RNA Council Stand, located adjacent the Ernest Baynes Stand overlooking the show ring, had been constructed. The Stand was originally two storeys. At some early period the northern end of the building was extended to incorporate an
