Cylindrical retorts of an old-fashioned retort plant, now burned down and 

 dismantled. These retorts are arranged in batteries of two and are heated 

 by direct heat underneath. Each retort contains about | of a cord and must 

 be loaded and unloaded by hand. The modern oven is a vast improvement 

 over this old-fashioned method.
