These two baby giant pandas (escorted by Zoologist John Tee-Van,) arrived safely in San Francisco last week after a hazardous journey by plane from Chungking to Manila, by ship from Manila to Hawaii, through the sub marine-infested Pacific in the first convoy to reach the West Coast since the Japanese attack. Captured last summer in the cool hills of inner China, they are presented to the U.S. by Mme. Chiang Kai-shek in gratitude for the activities of United China Relief. In a new, barless $15,000 home at New York City's Bronx Zoo, the new pandas will be weaned from bamboo shoots to a diet of Pablum, orange juice, milk, honey, raw eggs.
