From the Laboratory / Thomas A. Edison / Orange, NJ / June 21, 1923 / Mr. S.H. Caldwell / 103 Johnson Street / Lynn, Mass. / Dear Mr. Caldwell / There is only one thing which I wish to say in snarer to your letter of June 11th: I believe that combining practical experience with a college education is a fine idea — an idea which will certainly win out. / Yours very truly / [signed: Thos. A. Edison]
