Inventions that sparked economic advancement 1865-1917

Generally, it was found more economical in the early days of refrigeration to cool the cars with ice or frozen brine which was periodically replenished at icing stations along rail routes. In 1857, the first shipment of refrigerated beef was made from the Chicago stockyards to the East Coast in an ordinary box car packed with ice. 1873 Silo

The first modern silo, a wooden and upright one filled with grain, was invented and built in 1873 by Fred Hatch of McHenry County, Illinois, USA.
