The distribution of the various industries in the different parts of the country did not vary very much from that existing under previous régimes. Broadly speaking, no new development took place, every centre remaining in the situation determined by coal or the presence of raw material. The principal centre of the textile industry remained at Ghent, near the hemp-fields of the Lys; metal-works, glass-works, etc., were still grouped close to the four main coal-fields in the region of Mons, La Louvière (Centre), Charleroi and Liége; the number of men engaged on industrial production before the war had reached 1,500,000, among whom were 153,000 miners, over 149,000 metal workers, and over 129,000 textile workers.
