Let the pupils look the fat over and put it on to melt, watching it
carefully. While it is heating and cooling, discuss the process of
soap-making, the cost of materials, the care necessary in the making of
soap, and the importance of its use. Get ready the other materials, and
a box for moulding the soap, and let the pupils work together. After the
soap has hardened and been cut, have it put away on a shelf to dry.
