It produces enormous quantities of wheat, besides other cereals, of tobacco and temperate fruits. Flour-milling, pork-packing, and distilling are the chief industries. The most extensive coal-deposits in America are in this State; with navigable rivers on its borders, and traversing it Lake Michigan, a great canal, and the largest railway system in the Union, it is admirably situated for commercial development; originally acquired by Britain from the French, who entered it from Canada; it was ceded to the Americans in 1783, and admitted to the Union 1818; education is compulsory, and has a large and wealthy scientific and agricultural university at Urbana. Springfield is the capital; but Chicago is the largest city.
