In 1857, a U.S. patent was issued to Ephraim Ball for his mower design, which became the first widely successful of the two-wheeled flexible or hinged bar mowers. This “Ball's Ohio Mower” greatly influenced the change from single driving-wheel machines to those with double drivers. Ball began inventing with a turn-top stove. Then in 1840 he established a foundry for making ploughs. An excerpt on Ephraim Ball from A History of American Manufactures from 1608 to 1860 gives an insight to the development of mechanized agriculture in the farmlands of the United States in the mid-19th century.

On 1 Dec 1866, George Everest died. His name on Mount Everest honours his extraordinary work mapping India. Today's book pick is: The Great Arc: The Dramatic Tale of How India was Mapped and Everest was Named, by John Keay. This captivating story about the Great Trigonometrical Survey of India is steeped in the subcontinent's past, written in an elegant style that brings to life the personalities of the surveyors. Keay covers the science of surveying and the logistics (an army of men, instruments, elephants and horses hauling a half-ton theodolite and braving tiger-infested jungles). Yet George Everest was an irascible martinet, driven by an ego as monumental as Everest. With an eye for intriguing incident and an ear for the telling phrase, one of the finest writers on India vividly resurrects the nineteenth century's most ambitious scientific endeavor.
