Herbert Hoover actually said...

"I THANK YOU for your kind message sent as you crossed the frontier from the United States to Canada."

"Mrs. Hoover also joins me in thanking you and we both send you our best wishes for a pleasant visit in Canada and a good voyage home."

"we were all grateful for the opportunity of manifesting our sincere appreciation of the spirit in which you came to us."

"the peoples of Great Britain and the United States have been brought even closer together by your visit."
