In this map of Lower Egypt you will see named the Gulf of Suez, which is the end of the Red Sea. Up the Red Sea come ships from Aden and the Indian Ocean. Here, on the other hand, is the Mediterranean, through which we shall pass to the Atlantic Ocean. And here is Suez, and the Isthmus of Suez, with the line of the Suez Canal. All that is shown yellow is barren, waterless desert, but the parts tinted with green are fertile and cultivated. As you see from the map, the isthmus is about 100 miles across. Remember that the voyage from Bombay to Britain is some 7,000 miles long--3,500 miles as far as the Canal and 3,500 miles beyond the Canal. Between the Eastern Ocean and the Western Ocean is only the Isthmus of Suez, but this used to compel men to take their ships far south through rough seas, round the Cape of Good Hope. [Sidenote: 34. The Overland Route through the Desert.] Let us, therefore, cross into Egypt, and ask what it is that has made possible this great change in the route of commerce and empire. Before the Canal was cut, but when already steam had been applied to the moving of ships, there were a few years in which passengers and letters were taken by one ship from Bombay to the Isthmus of Suez, and then on by another ship from the other side of the Isthmus to Britain. They were carried across the desert on the backs of camels. Here we have a picture of the thirsty desert. See the bones of a camel which has fallen by the way; the flesh has been picked off by vultures, and the sun and air have dried what remained to cinders. The camel is often called “The Ship of the Desert,” and this camel must have broken down just as ships are sometimes wrecked. [Sidenote: 35. Cairo--The Citadel.] [Sidenote: 36.
