Whilst these sheets are still in the press, yet another theatre dies the apparently natural death of all such structures, that is, by fire. Portugal is this time the scene of the disaster, the sufferer being the Baquet Theatre in Oporto. The calamity was caused by the wings catching fire from a gas-jet, whereby the whole of the stage scenery was almost, immediately afterwards enveloped in flames, the furious progress of which it was found impossible to arrest. Here, then, was a striking instance of a holocaust being caused by the want of such a curtain as has been described; for, had such a thing been available, the stage would have been at once shut off from the auditorium, and even if it had not been found possible to save the structure, the fire, at any rate, would have been localised for a sufficient length of time, to have enabled the authorities to clear the building, and so have prevented the panic and horror which ensued, and the fearful sacrifice of life which humanity now deplores. It is worth while perhaps recording the foregoing, because there can be very little doubt that something of this kind will presently be made compulsory even in England for use in theatres and music halls generally. And it is believed, from the course matters are now taking in the United States, that the use of asbestos in some form or other will be made compulsory there for the shelvings and doors of public libraries and places for the custody of records, for sheathings between wooden floorings and below carpets, for hearthstones, for the linings and doors of elevators or lifts, and for the better preservation of Pullman cars from fire. The premises of the American Watch Case Company, of Toronto, have their floorings protected by an asbestos covering, and I saw an announcement recently in the _Sherbrooke Gazette_ that this covering had saved their premises from destruction by a fire which had occurred there. In connection with this part of the subject it may be added that various attempts have been made for the introduction of asbestos into the manufacture of lace curtains, dresses, &c., but I believe that the principal obstacle in the way of success in this line lies in the fact that in its present state, in the shape of curtains, for instance, it is found to be an obstinate holder of dust. This objection will, no doubt, be presently got rid of; and soon we may hope to have heard the last of those fearful scenes which have at times occurred from the firing of ladies' dresses at the footlights in theatres.
