Just for Fun Primary Sources

The Library of Congress has primary sources for the lighter moments too.  Witness Old Heidelberg on April Fools’ Day in 1905. http://www.loc.gov/pictures/item/det1994011460/PP/
This story demonstrates how much student pranks and education has changed and how much it remains the same: April the 1st was dreaded by most rural school teachers. The pupils would get inside and bar the teacher out. The teacher, who didn't act on the principle that discretion is the better part of valor, generally got the worst of it. Mr. Douglass soon learned this, and, on April Fool's Day, he would walk to the school, perceive the situation, laughingly announce there would be no school until the morrow, and leave.
          Dr. Samuel B. Lathan, circa October 10, 1940.

Finally, we hope you will enjoy Collecting cards with pictures of events in ballooning history from 1783 to 1883 at the Library of Congress.  See a wonderful blog entitled Pictures to Go: Up in the Air by Kristi Finefield.   http://blogs.loc.gov/picturethis/2015/03/pictures-to-go-up-in-the-air/
