In September of 1923,
Arthur E. Raymo went on a business trip to Michigan, Ontario and New York. He visited other manufacturing plants, presumably to study their procedures and bring back ideas to his own alloy plant in Chattanooga. He rode from city to city by train and, when he had time, he sent home letters to his wife Margaret and family.
Here is one such letter Arthur wrote from
Niagara Falls, New York.
