WASHINGTON--The United States moved on two fronts today to strengthen its defense cooperation with Canada.

President Roosevelt in a special message to Congress revealed he has created an advisory committee to conduct preliminary work on the projected development of power on the St. Lawrence River for defense industries.

Concurrently, it was learned that the U. S. army air corps and the Canadian air force each will got about half of the 300 American pursuit planes and light bombers originally ordered by Sweden. The Swedish government contracted for the planes early in 1939, but shipment was held up under the export licensing control system for fear they might fall into German hands.
