the way both to demagnetize shipping so that it would
 
not attract th mines, and also to attract the mines
 
to special magnets so that they could be destroyed. He

of the equator did not attract the magnetic mines.
 
     With regard to submarines, Mr. Churchill stated the
 
Germans were only putting out one a week. The British
 
and French had positively destroyed forty-three since

and over a period of a few months prove that it was
 
mastered.
 
     Before I left Mr. Churchill took me to the other end

maps show the precise location of every merchant ship of
 
British registry throughout the world. Every half-hour
 
the locatlons, are changed to bring them up to date in
 
accordance with the latest, radio bulletins of position.
 
Every convoy is shown, as well as the position of those
 
vessels which are either too speedy, or too slow to be
 
subject to convoy. This War Maps Room is one of the
 
most impressive things I have seen. It is a demonstration
 
                                                  of
