As each day passed I would learn, in our talk, something about the little prince's planet, his departure from it, his journey. The information would come very slowly, as it might chance to fall from his thoughts. It was in this way that I heard, on the third day, about the catastrophe of the baobabs. This time, once more, I had the sheep to thank for it. For the little prince asked me abruptly-- as if seized by a grave doubt-- "It is true, isn't it, that sheep eat little bushes?" "Yes, that is true." "Ah! I am glad!" I did not understand why it was so important that sheep should eat little bushes. But the little prince added: "Then it follows that they also eat baobabs?" I pointed out to the little prince that baobabs were not little bushes, but, on the contrary, trees as big as castles; and that even if he took a whole herd of elephants away with him, the herd would not eat up one single baobab. The idea of the herd of elephants made the little prince laugh. "We would have to put them one on top of the other," he said. But he made a wise comment: "Before they grow so big, the baobabs start out by being little." "That is strictly correct," I said. "But why do you want the sheep to eat the little baobabs?" He answered me at once, "Oh, come, come!", as if he were speaking of something that was self-evident. And I was obliged to make a great mental effort to solve this problem, without any assistance. Indeed, as I learned, there were on the planet where the little prince lived-- as on all planets-- good plants and bad plants. In consequence, there were good seeds from good plants, and bad seeds from bad plants. But seeds are invisible. They sleep deep in the heart of the earth's darkness, until some one among them is seized with the desire to awaken. Then this little seed will stretch itself and begin-- timidly at first-- to push a charming little sprig inoffensively upward toward the sun. If it is only a sprout of radish or the sprig of a rose-bush, one would let it grow wherever it might wish. But when it is a bad plant, one must destroy it as soon as possible, the very first instant that one recognizes it. Now there were some terrible seeds on the planet that was the home of the little prince; and these were the seeds of the baobab. The soil of that planet was infested with them. A baobab is something you will never, never be able to get rid of if you attend to it too late. It spreads over the entire planet. It bores clear through it with its roots. And if the planet is too small, and the baobabs are too many, they split it in pieces...
