At a quarry in Kajjansi between Kampala and Entebbe I met several children who work full time crushing rocks for a living. The sturdier kids work below ground level, with sledgehammer, wedges and picks to break chunks of rock off the rock face. The chunks are sent up topside where crews of adults and children, often whole families, sit on the ground hammering the big chunks to break off smaller pieces for use in paving and concrete making. There is a compulsory education law in Uganda, but at least 15% of school age children are working full time and are not in school. Even the free public schools require some fees for books and materials and food. Many families cannot afford even these minimal fees. See more pix in the gallery.
