EISENHOWER IN ARGENTINA: Buenos Aires, February 26 – US President Dwight D. Eisenhower arrived in Argentina from Brazil today, continuing his tour of South America. The US is trying to organize a campaign to fight the infiltration of communists in South American states. Brazil has in recent years been distancing itself from the US and as a consequence Washington might be forced to provide it with considerable economic aid. In Buenos Aires, where he received a warm official welcome, Eisenhower gave a speech about the strength of free nations that were able to confront external threats. Nevertheless there were some hostile demonstrations, even attempts to set off bombs, and shouts of «Peron, Peron!» by small groups. STRIKE IN POLAND: Warsaw, February 26 – According to well-informed sources, last Friday the 5,000 workers at a factory in Poznan where train carriages are repaired, stopped work in protest at a reduction in pay. About 30 people were immediately sacked and the next day work resumed as normal. Strikes are legal in Poland but only when all other attempts at negotiation have been exhausted.
