Your telegram S.W.18.  If the United Kingdom asks us directly
we can give an answer. Until then proposal would be regarded as
gratuitous intermeddling in a situation of extraordinary
difficulties. Slater's sudden departure  has undoubtedly given
rise to rumours and suspicions voiced to me by Litvinoff. 
These may well be aggravated by pushing in as Bruce suggests. In
any event, the Prime Minister will be here in person next week.
Bruce probably is unaware of that and I am not at liberty to allow
you to inform him. Matter could certainly be discussed with the
Prime Minister at Washington.
I do not think there is the slightest reason to precipitate
immediate decision which would also be probably resented by
Washington. However, if we get request later from Churchill, we
can consult at Washington both persons chiefly concerned. 
of course, our staff difficulties in Russia are very great indeed
as you very well know but Bruce merely brushes these aside.
I think that Bruce should also communicate with me direct in a
matter of this kind.
I therefore advise extreme caution.
