This and the next two pictures depict stages in drawing tubes for beads. In the first panel a boy is attaching an iron rod to the end of a hollow gather of glass held by the master. The second picture shows him running the tube out. The third shows the cutting of the now-cooled tube into shorter pieces which are then bundled. Wooden rails hold the tube.
