"We hope that there may be conveyed to you during your visit to our country the equal warmth and good feeling of the people of the United States toward Mexico."

"I want you to feel at home in my house, as I do in yours."

"We hope to repay, in some small part, the hospitality which Mrs. Johnson and I enjoyed last year in Mexico City."

"If ever proof was needed that this was indeed Mexico's policy toward her neighbors, we received it less than a month ago in the floods along the Rio Grande."
