HC Deb 12 March 1912 vol 35 c962
Mr. FREDERICK WHYTE

asked the President of the Board of Trade what has been the result of the recent experiments in Hertzian wave fog signals made by the French lighthouse authorities?

The PARLIAMENTARY SECRETARY to the BOARD of TRADE (Mr. J. M. Robertson)

I am informed by the Trinity House that they understand that the French Government do not expect to establish the experimental stations until the spring of this year, and that the lightship on which some of the experiments will be made has not yet been built. As I informed by hon. Friend on 29th November last the French lighthouse authorities have undertaken to supply the Trinity House with information as to the progress and results of their experiments.
