I assume that the so-called "fuel savers" mentioned are the chemicals sold for spraying over coal or coke. Several of these preparations were carefully tested on coal fires a number of years ago, on behalf of the Fuel Research Board, and found to have no effect. A similar investigation, made more recently by the United States Bureau of Mines, showed that treatment with certain proprietary products made no difference on tests of commercial boilers.
Is not my hon. Friend aware that one of these products upon analysis proved to be nothing more than common salt, and are there no means of taking action in order to protect the public?
