West German Foreign Minister Heinrich von Brentano hurried into Geneva to take over from Ambassador Wilhelm Grewe at the delegation table to balance the rank of East Germany's Foreign Minister Lothar Bolz.

Before the third session began, May 13, Brentano called on Russian Foreign Minister Andrei Gromyko at the Russian Permanent delegation's 18th century villa near the Palais de Nations for an eighty-minute talk in private.

As they conferred, reporters lay in wait outside the gates; cameramen turned their lenses on the cows and children in the grounds of the villa. Finally Brentano came out but made no statement.

Having heard Brentano's report on the Bonn Government's views on Berlin, Gromyko conferred with East Germany's Foreign Minister Lothar Bolz. Although Herr Bolz - like Brentano - has only the status of adviser at the Conference, the Soviet-backed East German Government scored a major round in East-West politics in general, the Berlin problem in particular: the West accept its presence yet officially refuse to recognize the East German Government.

The East German delegation in this lakeside city of fine villas and hotels somewhat piqued conventionally-minded citizens by accommodating themselves in railcoaches shunted into sidings. Here some delegatio members and aids sleep, eat, wash laundry, Keen-nosed Geneva citizens noted too that the East German delegates run their cars on East German petrol - distinctive for its odour.
