Read the excerpt from chapter 8 of The Travels of Marco Polo and study the map.[This] is an island lying about 1,000 miles south of Socotra. The people are Saracens who worship Mahomet. They have four sheikhs—that is to say, four elders—who exercise authority over the whole island. You must know that this island is one of the biggest and best in the whole world. It is said to measure about 4,000 miles in circumference. The people live by trade and industry. More elephants are bred here than in any other province; and I assure you that not so many elephant tusks are sold in all the rest of the world put together as in this island and that of Zanzibar.
