Annotation
[1] AES, DLC-RTL. Lincoln's endorsement is written on a letter from Francis L. Capen, April 25, 1863. In the center of Capen's one-page letter appears his card, inscribed as follows: ``Thousands of lives & millions of dollars may be saved by the application of Science to War. Francis L. Capen. Certified Practical Meteorologist & Expert in Computing the Changes of the Weather.'' The letter requests a favorable reference to the War Department and concludes, ``I will guarantee to furnish Meteorological information that will save many a serious sacrifice.'' Other letters from Capen in the Lincoln Papers demonstrate that he was more of a crank than a scientist.
