programmes more than double the present projects, including all increases now contemplates.
     The concluding arguments, I regret to say, are based on calculations which can be torn to

     I have received from one of the Canadian authorities a statement of output for 1942,
which I am assured will be realised.
     This Canadian output should be increased fifteen times by the United States, taking into
