The Secretary of State to the Ambassador in Italy (Child)
Department has no objection to your making discreet inquiries in this matter from all sources which might be able to give information.
If it should be necessary to approach the Russians directly, it would be preferable to do so through a reliable agent. If a member of the Russian Delegation should desire to see you, you may receive him personally and informally and report whatever he might have to say. Department relies upon your discretion and desires that every effort be made to avoid publicity.
