Geography
a description of the earth's surface. The position of the earth in the universe and its relation to the other heavenly bodies fall within the province of astronomy. The make-up of the earth and its history before it became fit for the habitation of man belong to geology. The study of the surface, particularly the study of the earth as a home, constitutes the subject of geography. Indeed, Arnold Guyot, the eminent geographer, named his monumental work Earth and Man.
The ancients were acquainted with but a small portion of the earth's surface. To Strabo, a learned Greek, resident in Rome, we owe a geographical work in seventeen books, virtually a geographical cyclopedia, in which the world's knowledge of geography at the time of the birth of Christ is given in systematic form. In Strabo's geography the size and shape of the earth are given correctly, but the land mass is confined to the Mediterranean countries and southern Asia as far as the mouth of the Ganges. Around this territory, which on maps has somewhat the form of an oval about twice as long as it is wide, lay the all encircling ocean into which not only the Mediterranean and the Red Sea, but the Caspian as well, are represented as opening. What to the ancients seemed vast regions of this single small land mass are denoted on maps of that time as inhabited by Hyperboreans and other little known or imaginary people beyond the pale of civilization.
The enlargement of geographical knowledge has been brought about in various ways. One of the earliest, most persistent, and effective motives is the search for wealth, the love of gainful trade. Far back in the mythological age the Greek Jason and his companions are reputed to have sailed eastward in search of the Golden Fleece. The Phoenicians are known to have visited Cornwall in search of tin, and are believed to have bartered for amber on the shores of the Baltic. Motives of conquest and commercial supremacy led Alexander to penetrate the plains of the Indus. The invention of the compass converted boatmen into sailors. Commercial enterprise led to the discovery of the New World and to the circumnavigation of the globe. Missionaries and merchants share in the honor of contributing to geographical knowledge. The mixed love of adventure, desire for gold, and thirst for glory that led Cortez, Pizarro, and De Soto, shaded off in later times into the spirit of scientific discovery that animated Mungo Park, Cook, Speke, Livingstone, Stanley, Humboldt, and Lewis and Clark. The history of Arctic discovery is a chapter in itself.
The body of geographical knowledge is now so great that it is divided into several subjects. At least four distinct branches are recognized:
1. Mathematical geography. This division includes the form, size, position, and motions of the earth, as well as the entire subject of map, globe, and chart making.
2. Physical geography. Under this head are included land, water, and air. Land masses, bodies of water, currents, winds, moisture, temperature, and, in general, the working of physical forces belong here.
3. Political geography. This is the ordinary geography of the school, dealing with countries, nations, and the industries by means of which man makes a living.
4. Commercial geography. The study of this branch includes not only the production of articles of commerce, but routes of travel and the trade of the world.
