"Then, besides, painted wood," continued Forester, "cannot be finished off so smoothly, and polished up so highly, as a wood which is black by nature. They have a way of staining wood, however, which is better than painting it."
"How is that done?" asked Marco.
"Why, they make a black stain," said Forester, "which they put upon the wood. This staining soaks in a little way, and blackens the fibres of the wood itself, beneath the surface. This, of course, will not wear off as easily as paint."
"I should not think it would wear off at all," said Marco.
"Yes," replied Forester, "for, if a cane is made of any wood stained black, after a time the wood itself wears away farther than the staining had penetrated. Then the fresh wood will come to view. So that, if you want anything black, it is much better to make it of a wood which is black all the way through.
"Besides," continued Forester, "ebony is a very hard wood, and it will bear knocks and rough usages much better than other kinds of wood which are softer. Once I made a carpenter an ebony wedge, to split his laths with."
"What are laths?" asked Marco.
"Laths are the thin split boards which are nailed upon the sides of a room before the plastering is put on. Sometimes laths are made very narrow, and are nailed on at a little distance from each other, so as to leave a crack between them. Then the plastering, being soft when it is put on, works into the cracks, and thus clings to the wood when it is dry and hard. If plastering was put on to smooth boards, or a smooth wall, it would all fall off again very easily."
"Yes," said Marco; "I have seen the plastering coming up through the cracks in the garret at your house in Vermont."
