In continuation of this subject it may be worth mentioning, as showing the amount of attention which is now being directed to this important matter, that an experiment was recently made in the neighbourhood of Oxford Street to test the fire-resisting qualities of another new curtain for the stage, said to have been invented by Captain Heath. This experiment took place within a specially built hoarding, within which there was erected a large model of the Drury Lane stage proscenium. Captain Heath explained to the company, invited to witness the experiment, that the curtain was made of asbestos and canvas, and was rolled on a block of wood placed underneath the front part of the stage, where it occupied an otherwise useless space, and in no way interfered with the business of the theatre. The sides of the model were made of iron plates, and the front entirely of wood. When certain catches were released counterbalancing weights came into action, and the curtain was run rapidly up from below. On reaching the top, it pressed tightly and automatically against the back of the proscenium, turning on at the same time a supply of water from a perforated pipe which ran along the whole length of the top of the curtain so as to keep it constantly wet. The arrangement of the switch used for communicating action to the curtain was such as to turn on the water and close the curtain against the sides at will. He also stated that communication with the lever of the switch could be fitted to any part of the theatre. A very severe fire test was employed. The model was first filled with inflammable materials such as shavings and large blocks of wood, over which petroleum was poured. At a given signal the curtain was raised and the fire lighted. The flames at once rose, accompanied with volumes of smoke, none of which, however, found their way to the front of the proscenium. The interior looked like a furnace. But so effectually were the flames shut off that it was possible to sit on the fore part of the stage without feeling the heat, the only thing noticeable being the steam arising from the wet canvas. This, Captain Heath explained, might be obviated by painting the canvas in oils. The fire burned fiercely for half an hour, and the universal opinion of those present was that the curtain was perfectly fireproof, and that its construction was as simple as it was useful for the purpose intended.
