"Then I should like a top made of lead," said Marco.
"It would spin very long," said Forester, "if it was well made, though it would require more strength to set it a-going well. But lead would be soft, and thus would easily get bruised and indented. Besides, black would be a prettier color for a top than lead color. A jet black top, well polished, would be very handsome."
"Is black a color?" asked Marco. "I read in a book once that black and white were not colors."
"There are two meanings to the word color," said Forester. "In one sense, black is a color, and in another sense, it is not. For instance, if a lady were to go into a shop, and ask for some morocco shoes for a little child, and they were to show her some black ones, she might say she did not want black ones; she wanted colored ones. In that sense, black would not be a color.
"On the other hand," continued Forester, "she might ask for silk stockings, and if the shopkeeper were to ask her what color she wanted, she might say black. In that sense, black would be a color."
"Which is the right sense?" asked Marco.
"Both are right," said Forester. "When a word is commonly used in two senses, both are correct. The philosophers generally consider black not to be a color; that is, they generally use the word in the first sense."
"Why?" asked Marco.
"For this reason," replied Forester. He was going on to explain the reason, when suddenly Marco's attention was attracted by the sight of a long raft of logs, which was coming down the river. They had been riding at some distance from the river, and out of sight of it, but now it came suddenly into view, just as this raft was passing by. There were two men on the raft.
"See those men on the raft," said Marco. "They are paddling."
