- The poem describes poor children in a classroom, with dirty yellow walls and donated posters. The children's faces are pale and gaunt, like rootless weeds, and their future seems bleak. Though maps and pictures depict a wide world, the children are far removed from nature, opportunity, and hope. Their lives are confined to the foggy slums. The poem asks those in power to open the children's minds by replacing classroom walls with inspiring visions of opportunity.
