October 18, 1767 — Mason and Dixon complete the surveying of the Line between Maryland and Pennsylvania

Charles Mason, a fellow of the Royal Society and noted astronomer, and his sometime assistant, land surveyor and amateur astronomer, Jeremiah Dixon, were hired by certain wealthy interests in what was then the British colony of America to conclude a number of difficult boundary disputes in the young colonies.

Landing in Philedelphia in 1763, Mason and Dixon spent the next four years painstakingly measuring and fixing the proper boundaries between the various colonies, ceasing their work on October 18, 1867. (A team of their subordinates completed the survey in 1787.)

The lines they laid down, although resurveyed since that time, formed the basic lines of the borders between the colonies (and later the states) of Delaware, Maryland, Pennsylvania and West Virginia. Later, as these states took different sides in the Civil War, the line came to symbolise the political and cultural border between the southern and northern states.

March 18, 1965 — Gene Seski crashes a truckload of bananas in Scranton, Pennsylvania

Gene Seski was an experienced truck driver who, on the 18th of March, 1965, was driving a semi-trailer load of bananas from the piers in New Jersey to the town of Scranton, Pennsylvania. His chosen route was Rt. 307, a long, slow descent that winds for two miles into Scranton. It features a section in which, over the course of a single mile, the road drops 500 feet in elevation.

For reasons unknown, Seski lost control of his vehicle. It was traveling at about 90 miles an hour when this happened, and the combination of the truck’s momentum and the downhill slope ensured that it traveled a considerable distance before it came to rest at the corner of Moosic St and S. Irving Ave. Seski did not survive the crash, and the thirty thousand pounds of bananas were scattered all about the vicinity, many of them smeared to a paste.
