小王子访问的第六颗星球比上一颗要大十倍。这颗星球上面住着一位老先生，他写了一本巨大的书。
“在这里！瞧！来了一位探险家。”老先生看到小王子时喊道。
小王子在桌旁坐下，有点气喘吁吁。他这次旅行有点久。
“你从哪里来的呀？”老先生问小王子。
“这一大本厚厚的是什么书？你在这里干什么？”小王子问道。
“我是地理学家。”老先生说。
“什么是地理学家？”
“地理学家就是一种学者，他知道哪里有海洋，哪里有河流、城市、山脉、沙漠。”
“这太有趣了。”小王子说，“最后在这里终于遇见一个人有真正的专业啦。”他瞥了一眼这位地理学家星球的四周。他还从来没有见过一颗如此雄伟的行星。
“这是美丽的星球。上面有海洋吗？”
“我不知道。”地理学家说。
“啊！”小王子大失所望，“那么，山脉呢？”
“我不知道。”地理学家说。
“那么，有城市、河流、沙漠吗？”
“我知道的不多。”地理学家说。
“可您还是地理学家呢！”
“一点不错，”地理学家说，“但是我不是探险家。我手下一个探险家都没有。地理学家是不去计算城市、河流、山脉、海洋、沙漠的。地理学家很重要，不能到处跑。他不能离开他的办公室。但他可以在办公室里接见探险家。他询问探险家，把他们的回忆记录下来。如果他认为其中有个探险家的回忆是有意思的，那么地理学家就对这个探险家的品德做一番调查。”
“这是为什么呢？”
“因为一个说假话的探险家会给地理书带来灾难性的后果。同样，一个太爱喝酒的探险家也是如此。”
“这又是为什么？”小王子说。
“因为喝醉了酒的人把一个看成两个，那么，地理学家就会把只有一座山的地方写成两座山。”
“我认识一个人，他要是搞探险的话，就很可能是个不好的探险员。”小王子说。
“这是可能的。因此，如果探险家的品德不错，就调查他的发现。”
“去实地考察吗？”
“不。那太复杂了。但是要求探险家提出证据来。例如，假使他发现了一座大山，就要求他带来一些大石头。”
地理学家忽然兴奋地忙乱起来。
“正好，你是从远方来的！你是个探险家！你来给我介绍一下你的星球吧！”
于是，已经打开记事簿的地理学家，削起他的铅笔来。他首先是用铅笔记下探险家的叙述，等到探险家提出了证据以后再用墨水笔记下来。
“怎么样？”地理学家充满期待地询问道。
“啊！我那里，”小王子说道，“没有多大意思，那儿什么都很小。我有三座火山，两座是活的，一座是熄灭了的。但是也很难说它还会不会喷发。”
“这确实难说。”地理学家说道。
“我还有一朵花。”
“我们是不记载花卉的。”地理学家说。
“这是为什么？这朵花是我的星球上最美丽的东西！”
“我们不记录它们，”地理学家说，“因为花卉是短暂的。”
“什么叫短暂？”
“地理学书籍是最严谨的书。”地理学家说道，“这类书是从不会过时。很少会发生一座山变换位置，很少会出现一个海洋干涸的现象。我们记录永恒的东西。”
“但是熄灭的火山也可能会再复苏的。”小王子打断了地理学家，“什么叫短暂？”
“火山是熄灭了的也好，苏醒的也好，这对我们这些人来讲都是一回事。”地理学家说，“对我们来说，重要的是山。山是不会变换位置的。”
“但是，‘短暂’是什么意思？”小王子再三地问道。他一旦提出一个问题是从不放过的。
“意思就是有很快就会消失的危险。”
“我的花是很快就会消失的吗？”
“那当然。”
小王子自言自语地说：“我的花是短暂的，而且她只有四根刺来对抗这个世界！可我还把她独自留在我的星球上！”
这是他第一次产生了后悔，但他又重新振作起来：“您是否能建议我下一站去什么地方看看？”小王子问道。
“地球，”地理学家回答他说，“它很出名……”
于是小王子就走了，他一边走一边想着他的花。
Chapter 15
The sixth planet was ten times larger than the last one. It was inhabited by an old gentleman who wrote voluminous books.
"Oh, look! Here is an explorer!" he exclaimed to himself when he saw the little prince coming.
The little prince sat down on the table and panted a little. He had already traveled so much and so far!
"Where do you come from" the old gentleman said to him.
"What is that big book" said the little prince. "What are you doing""I am a geographer," the old gentleman said to him.
"What is a geographer" asked the little prince.
"A geographer is a scholar who knows the location of all the seas, rivers, towns, mountains, and deserts.""That is very interesting," said the little prince. "Here at last is a man who has a real profession!" And he cast a look around him at the planet of the geographer. It was the most magnificent and stately planet that he had ever seen.
"Your planet is very beautiful," he said. "Has it any oceans""I couldn't tell you," said the geographer.
"Ah!" The little prince was disappointed. "Has it any mountains""I couldn't tell you," said the geographer.
"And towns, and rivers, and deserts""I couldn't tell you that, either.""But you are a geographer!"
"Exactly," the geographer said. "But I am not an explorer. I haven’t a single explorer on my planet. It is not the geographer who goes out to count the towns, the rivers, the mountains, the seas, the oceans, and the deserts. The geographer is much too important to go loafing about. He does not leave his desk. But he receives the explorers in his study. He asks them questions, and he notes down what they recall of their travels. And if the recollections of any one among them seem interesting to him, the geographer orders an inquiry into that explorer’s moral character.""Why is that"
"Because an explorer who told lies would bring disaster on the books of the geographer. So would an explorer who drank too much.""Why is that" asked the little prince.
"Because intoxicated men see double. Then the geographer would note down two mountains in a place where there was only one.""I know some one," said the little prince, "who would make a bad explorer.""That is possible. Then, when the moral character of the explorer is shown to be good, an inquiry is ordered into his discovery.""One goes to see it"
"No. That would be too complicated. But one requires the explorer to furnish proofs. For example, if the discovery in question is that of a large mountain, one requires that large stones be brought back from it."The geographer was suddenly stirred to excitement.
"But you— you come from far away! You are an explorer! You shall describe your planet to me!"And, having opened his big register, the geographer sharpened his pencil. The recitals of explorers are put down first in pencil. One waits until the explorer has furnished proofs, before putting them down in ink.
"Well" said the geographer expectantly.
"Oh, where I live," said the little prince, "it is not very interesting. It is all so small. I have three volcanoes. Two volcanoes are active and the other is extinct. But one never knows.""One never knows," said the geographer.
"I have also a flower."
"We do not record flowers," said the geographer.
"Why is that The flower is the most beautiful thing on my planet!""We do not record them," said the geographer, "because they are ephemeral.""What does that mean— ‘ephemeral'""Geographies," said the geographer, "are the books which, of all books, are most concerned with matters of consequence. They never become old-fashioned. It is very rarely that a mountain changes its position. It is very rarely that an ocean empties itself of its waters. We write of eternal things.""But extinct volcanoes may come to life again," the little prince interrupted. "What does that mean— ‘ephemeral'""Whether volcanoes are extinct or alive, it comes to the same thing for us," said the geographer. "The thing that matters to us is the mountain. It does not change.""But what does that mean— ‘ephemeral'" repeated the little prince, who never in his life had let go of a question, once he had asked it.
"It means, ‘which is in danger of speedy disappearance.'""Is my flower in danger of speedy disappearance""Certainly it is."
"My flower is ephemeral," the little prince said to himself, "and she has only four thorns to defend herself against the world. And I have left her on my planet, all alone!"That was his first moment of regret. But he took courage once more.
"What place would you advise me to visit now" he asked.
"The planet Earth," replied the geographer. "It has a good reputation."And the little prince went away, thinking of his flower.
