"Big Tiger had never had a map in his hand before, but he pretended to know all about maps and remarked airily: “I can’t read the names on this one because they’re in English.” Christian realized he would have to show his friend how to read a map. “The top is north,” he said. “The little circles are towns and villages. Blue means rivers and lakes, the thin lines are roads and the thick ones railways.” “There’s nothing at all here,” said Big Tiger pointing to one of the many white patches. “That means it’s just desert,” Christian explained. “You have to go into the desert to know what it looks like.”….. “That’s a fine map,” said Big Tiger. “It’s useful to be able to look up beforehand the places we reach later.”….. “Are there bandits about here?” asked Christian. “Perhaps it’s written on the map,” Big Tiger ventured. “Look and see.”…..
