Welch, was simple enough to understand, if not to perform. Mention too must be made of Rusholme's Indoor Fireworks which never failed to attract a crowd. Indeed all the experiments were performed and explained with confidence. In the Biology Department Ford's Demonstration Frame of Bees evoked much interest, to which the chorus of chickens provided a musical background. The School Zoo, also, under the direction of Richardson, was a sure attraction. In the Geography Section of the Exhibition typical work of different sections of the School was attractively displayed, together with a full history and plans of the School's adopted ship S.S. "Mountpark". The Meteorological Department displayed its depressing records, and published an hour to hour commentary on the weather during the Exhibition, producing the astounding information that over 10,000 gallons of water had fallen during the period over the area of the cricket square ! A very interesting innovation in this year's Exhibition was the inclusion of a Hobbies Room, where many models of ships and aeroplanes made by boys were displayed, together with a collection of firearms. In addition there were two working model railways, which proved a never ending source of attraction and were invaluable as a means of finding any lost children. In addition to the many exhibits, of which only a few have been mentioned, there were also lectures, demonstrations, and films, given at intervals. The lectures were given by Robinson and Youll on "Liquid Oxygen' and proved so popular that an extra had to be arranged at the end of the second day. Rigg and Weightman gave demonstrations of X-Ray and High Voltage experiments, while Bolton and Moore, J. R., lectured on Colour and Fluorescence. Among the films shown were one on The Phase Contrast Microscope, one on the Vocal Chords, and one on Science in the Orchestra. The Junior School made their contribution to the Exhibition in the form of a room of Junior School Exhibits of Botanical and Natural History specimens, geographical diagrams and meteorological charts, while J.VI demonstrated York's water and sewage system. The share of the C.C.F. too in the Exhibition must not be forgotten. The Signals Section was responsible for maintaining a network of internal communications, of which the visitors were invited to make use, and demonstrated the working of the Signals Telephone Exchange and the Inter-Schools Network transmitter and receiver. Finally the Artillery Section of the C.C.F. marked the close of each session of the Exhibition by the firing of a blank round from a 25 pounder gun, with resounding success. Besides the School exhibits there were on show several pieces of apparatus which are normally outside the usual school activities and which were provided by the courtesy of various outside firms and
