In 1932, J. O. Smith, Agricultural Engineer at Delta Branch Experiment Station in Stoneville, MS, attached a small anhydrous ammonia cylinder to a plow in such a manner that the NH3 was released in the soil. The plow, a Georgia Stock, was pulled by a gray mule named Ike. This was the first known use of anhydrous ammonia as a soil-applied crop fertilizer. The crude apparatus and the anhydrous ammonia it applied provided a much needed source of nitrogen for the otherwise rich alluvial soils of the Mississippi Delta.
Agricultural Aviation Began In 1921 When C. R. Neillie Got A Military Plane To Dust Catalpa Trees Near Troy, OH. In 1922 B. R. Coad And C. E. Wollman Began Research At Tallulah, LA To Control Boll Weevils In Cotton. They Developed Equipment Using Venturi Induction, Ram Air Pressure And Hopper Agitation. G. B. Post And Wollman Made The First Commercial Dust Applications In Macon, Ga In 1924. In 1925, 18 Aircraft Treated 60,000 Acres Of Cotton Across The South. In 1928, Delta Air Service Was Organized.
This rocket propulsion test complex was created to flight-certify all first and second stages of the Apollo Saturn V rocket. The first test-firing occurred on April 23, 1966. Subsequent to the Apollo Program, these test stands were modified to support the testing requirements of the Space Shuttle Main Engine. Every astronaut who traveled to the moon aboard Saturn V Rockets and into space aboard the Space Shuttle, did so on rocket stages and engines that were first proven flight-worthy on these test stands.
The Cairo is the sole survivor of the fleet of river gunboats built by the Union during the Civil War with the object of controlling the lower Mississippi River. Designed by Samuel Pook and built by James B. Eads, it saw limited battle and was sunk on the Yazoo River in 1862 by newly developed electronically detonated mines, becoming the first craft ever sunk by this predecessor to torpedo technology. The 175-foot ironclad vessel had 13 guns.

In the early 1900s, Union Station was the hub of passenger railroad traffic in the central United States. It was one of the first stations to serve as a centralized terminal for multiple railroad lines. It originally served 22 rail lines; 13 from the east and nine from the west.
