Certain major tours of the two northern territories will be found in the preceding section; others are to be found in the context of elections, electioneering, and party politics in series 5 of this catalogue. There is some overlap between the ensuing material and the subsequent section: invitations. Two long series of running files (Liaison Office UA4504/1, becoming UA4525, then Fed 5009/2 and Minister of Transport 133; and PM 60/A-N) are now represented by 410/2-418/3. The heading 'tours' was abandoned in 1960 or 1961 and the series replaced by box files containing 'engagements', 'invitations', etc.

Invitations outside Salisbury (Harare): the replacement for the abandoned 'tours' series and arranged as 419/1-5 and 420/1-6 from two box files, following the headings of the file dividers and the chronological arrangement therein by date of the function - not by the date of the correspondence.
