The principal industry of Hungary is flour-milling. The number of steam-mills, which in 1867 was about 150, rose to 1723 in 1895 and to 1845 in 1905. Between 3,000,000 and 3,200,000 tons of wheat-flour are produced annually. The principal steam-mills are at Budapest; large steam-mills are also established in many towns, while there are a great number of water-mills and some wind-mills. The products of these mills form the principal article of export of Hungary.
