"The bass of the bass-wood is used for making ropes, mats, shoes, hats, and other things. You know, too, how useful the bass matting is in the garden for tying-up purposes and for covering plants in the winter time.

"Do you know what my white collar is made of, Norah?""It is made of linen," she replied.

"Quite right," said Fred, "but what is linen?""Linen comes from the flax plant."
