New contract demands were presented to U.S. authorities by leaders of 24,000 workers on strike at American bases in the Philippines. Both sides expressed hopes of ending the six-day-old walkout soon. Rear Adm. Edwin Kohn, commander of U.S. forces in the Philippines, said he hopes a third round of negotiations today will end the deadlock. "Perhaps Good Friday will bring a good message for both our employees and for ourselves," he said. Meanwhile, pickets continued to block entrances to Subic Bay Naval Base and Clark Air Base.
