"I can look back to the nights on a passenger ship when one wax candle afforded all the illumination between two cabins. Hot water was carried to the passengers in jugs; baths were luxuries. Smoke rooms were just being added; libraries were practically unknown. Progress has meant two things- speed and comfort, though with us there has always been the matter of safety first. Out of common experience a hundred devices have come into use that make for safety- inventions apart altogether from life boats, bulkheads and so on. Wireless, wireless direction finders, the fathometer for taking soundings, and smoke and fire detectors."
