At Treasure Island on the Delaware River in the United States, the First Order of the Arrow ceremony takes place and the Order of the Arrow is founded to honor American Boy Scouts who best exemplify the Scout Oath and Law.

The Delaware River is a major river in the Mid-Atlantic region of the United States and is the longest free-flowing (undammed) river in the Eastern United States. From the meeting of its branches in Hancock, New York, the river flows for 282 miles (454 km) along the borders of New York, Pennsylvania, New Jersey, and Delaware, before emptying into Delaware Bay.

The Order of the Arrow (OA) is the honor society of Scouting America, composed of Scouts and Scouters who best exemplify the Scout Oath and Law in their daily lives as elected by their peers. It was founded as a camp fraternity by E. Urner Goodman, with the assistance of Carroll A. Edson, in 1915. Although it began without national approval, it was eventually admitted as an "Official Experiment" of Scouting America. In 1948, following an extensive review, it became a program of the organization.

July 16 is the 197th day of the year in the Gregorian calendar; 168 days remain until the end of the year.
