I think it is very important that I should have a talk with you as soon as possible on a highly secret matter. I mentioned it to you shortly after you took office but have not urged it since on account of the pressure you have been under.

The Japanese campaign involves therefore two great uncertainties; first, whether Russia will come in though we think that will be all right; and second, when and how S-1 will resolve itself.

Over any such tangled wave of problems the S-1 secret would be dominant and yet we will not know until after that time probably, until after that meeting, whether this is a weapon in our hands or not.

After I had gone through this matter with the President I told him of my condition of health and that my doctors felt that I must take a complete rest and that I thought that that meant leaving the Department finally in a short time.

The President so far has struck me as a man who is trying hard to keep his balance. He certainly has been very receptive to all my efforts in these directions.
