Lithograph by Denis Dighton, showing a small-scale brick making operation. Between 1801 and 1911, the population of Britain trebled to 45 million. In addition, the proportion of people living in towns increased from 20 to 80 per cent. This rapid urbanisation made huge demands on the brick-making industry; by the middle of the 19th century, 500 million bricks were being produced every year in the London area alone. By 1900 virtually all bricks were machine-made. Printed and published at Rowney & Forster's Lithographic Pres, 51 Rathbone Place, London.
