Command Pro ject 3 . \ Copies Referred To........................ No. of Enclosures I think it unnecessary to put into effect at once the procedure suggested in your letter for specially opening a channel of communications to be employed in the event that issues arise involving the use of atomic weapons. Before we take these steps it seems to me desirable to proceed further with our discussions with the United States Government. Your suggestions relate wholly to the means whereby ' the Washington-Ottawa teletype may be opened for communication on this subject in the event of an emergency arising after the normal hours of operation and to the employment of special rockex tapes for this purpose. I think it may be well to make such tapes available before long and also to institute a system whereby one of two or three named operators at each end may be called upon to open the line whenever it is not in use. I believe, however, that we shall have to supplement these emergency arrangements in order to ensure in extreme circumstances greater celerity in communicating from Washington to Ottawa. It might take as much as two hours under your suggested procedure 2 to J get the line open and to begin the despatch of a message. Could we not work out a simple telephone code which would be held here perhaps by Messrs. Matthews and Ignatieff and myself and at the Ottawa, end by three or four officers of the Department? Such a code could be employed at least to convey the initial warning so that the Ministers concerned in Ottawa could be alerted while the teletype line is being opened and a message transmitted. H.
