A TEMPERANCE DEMONSTRATION AT THE CRYSTAL PALACE.
Owing to the circumstance that the Handel Festival is always held at the Crystal Palace, the orchestra in the central transept of the Palace of Glass is known as the Handel Orchestra. It can accommodate no fewer than 4,000 persons. The dimensions of the transept, which has a diameter twice as great as that of the dome of St. Paul's Cathedral, can only be realised when it is crowded, as in onr picture, which shows in progress the great temperance fête that is held at the Crystal Palace every year. The organ, which is supplied with air by hydraulic machinery, boasts 4384 pipes, and cost £6,000. The acoustic properties of the building are admirable for large volumes of sound.
