THE STORY OF ARTIFICIAL SILK are then twisted into threads and wound on big bobbins. The finest filaments are made by pulling the filament as it comes out. They can now be made as fine as the fila- ments of the silkworm. Before cotton fibres can be used, they must be cleansed from oil, fat, wax and colouring matter. They must be boiled, bleached, dried and teased out. The yarn made from wood alone is a pale cream, while the yarn made from cotton is a bluish- white. The cotton yarn is 25 per cent. stronger than the wood pulp yarn. Wood fibre, we have learned, is a very strongly made substance. The microscope shows that it is made of peculiarly elongated cells—spindle-shaped and pointed at the ends. This sort of cell gives greater strength and tenacity than the structures that have spherical cells. Also, it gives greater density. You could, for instance, pack cartridges together more tightly than bullets. _ Nature designed a specially shaped cell in the making of trees. We have only recently appreciated this fact. There seems to be no limit to the number of new uses 20
