What to do about nudes, if anything, is always more or less of a ticklish problem. No matter how 20th-century we are or wish to be, some of us have inherited enough from the Mauve Decade, or have been surrounded by the traditions of Victorianism to such an extent, that the very word, Nude, is often veiled in whispers even if the object itself is veiled in nothing more than the atmosphere.
As for maps and their makers, Ries has many thoughts:
The first matters to be charted were direction and distance and these are still essential to every map. If you hear of that better place you can keep going until you get there if you but travel in the right direction. (p. 12)
Having north at the top of the map, we are used to the shapes of countries in this position. It would be the same world if we turned it upside down and had the south at the top, but try it once and you will see how unfamiliar and confusing it looks so. Yet the world is so upside down in most particulars right now, that perhaps it would be more true to print the maps that way after all. (p. 12)
In the jungles of Bengal they have a custom of breaking a branch from the wayside, and when it wilts it is considered that a krosh has been traveled. They do not realize that this varies with the season the type of tree from which the branch is taken, the speed of the walker or his idea of wilting! (p. 13)
One long-established concern publishing maps is in touch with all foreign governments through a branch office in Washington which contacts all the embassies. They consider a man in their cartography department an apprentice for the first three or four years of service which will give you a clue to the difficulty and importance of this type of work.

III. THE HUMAN SIDE OF MAP MAKING
Once upon a time the nations of the world knew little or nothing of one another: The hazards of travel in an uncharted world prevented people from going far afield. What lay beyond the horizon? Who dwelt there? These questions were answered by silence or by mythical imaginings. But necessity and curiosity joined hands and impelled discovery of these unknown places. Which way to a better land? How far to more fertile ground? These questions were answered by a map.
The first matters to be charted were direction and distance and these are still essential to every map. If you hear of that better place you can keep going until you get there if you but travel in the right direction.
To get this sense of direction you must start from somewhere. Today maps have the true north at the top. This was not always so. The religious movements of the Middle Ages developed special reverence for the East. Paradise itself was represented on the maps and was supposed to be in the Garden of Eden, in the East. But Paradise was Heaven, and Heaven was above, so the East was at the top of the map and there it remained until the compass came along and displaced Paradise by pointing north itself.
Having north at the top of the map, we are used to the shapes of countries in this position. It would be the same world if we turned it upside down and had the south at the top, but try it once and you will see how unfamiliar and confusing it looks so. Yet the world is so upside down in most particulars right now, that perhaps it would be more true to print the maps that way after all.
A map is not earth size, of course, so that distances must be represented to a scale. Otherwise your map is too vague to have much use. It is harder to do this than to get direction because a knowledge of mathematics is needed both to measure distance on the ground and still more to show it on a map. In some parts of India a unit of measurement, the krosh, is given as “two statutory miles, more or less.” In the jungles of Bengal they have a custom of breaking a branch from the wayside, and when it wilts it is considered that a krosh has been traveled. They do not realize that this varies with the season the type of tree from which the branch is taken, the speed of the walker or his idea of wilting! Obviously mapmaking could not advance far until some facts of mathematics and astronomy could be applied. The best early maps came from Egypt, Babylon, China and Greece where these abilities first flourished.
The absence of such knowledge in most of Europe during the middle ages led the monks who made the maps never to leave any blank space on a map. To do so was an open confession of ignorance. They filled up all vacant areas with elaborate decorations-sometimes of fantastic creatures, or of legendary tales. Through the 18th century maps were decorative rather than practical, truly works of art, and are even now collectors’ items of rich beauty. Perhaps as an alibi to conceal their lack of accurate data, the idea was allowed to get around that accurate observations would be of value to trade rivals or enemies.
Of course, there were always some serious geographers who tried to promote accuracy in maps. Ptolemy, a famous Egyptian astronomer of the 2nd century, was first to draw the equator upon a globe and measure off the lines of latitude and longitude. Such lines, he explained, would locate any place on the map better than any amount of description. He also pointed out that a flat sheet of papyrus or paper would not fit around a sphere and that flat maps would involve too much distortion to be accurate. For a long time he pondered, “How can I show a map of the globe on a flat surface without too much distortion?” And then he had an idea. He took a cone and fitted a piece of papyrus around it tightly. It went on without any bulges, and when he took it off, it could be flattened out. He placed the cone, which was hollow, over the globe as far as the equator and drew his lines upon it. Then he took another cone going from the South Pole to the equator, and so invented the conical projection for flat maps. Ptolemy’s contributions to map-making were of great importance, but during the centuries new discoveries were made which were not on his maps. Moreover they had some inaccuracies of their own due to the unreliability of his sources, although his scientific methods were correct.
Mercator, a Flemish mathematician in the 16th century recognized the troubles with the earlier maps and decided to make something that would combine their advantages and remove their faults. Where Ptolemy used a conical projection, Mercator devised one based on a cylinder, and this solved the problems he had set himself.
The difficulties of making a map increase when we try to show on a flat surface the variations in height such as hills or mountains, yet their importance is too great to overlook. Mountains are not only a distinguishing physical characteristic of a region, but they affect rainfall and climate; they are the sources of rivers; they influence the amount of timber or the agricultural conditions; they serve as political boundaries and in many other ways. At first glance it would seem that the best way to show these would be on an actual model. However, models are costly to produce and cumbersome to handle, as they cannot be rolled, bound, folded or otherwise carried around conveniently. Most important, however, there has to be a different scale used for horizontal and vertical distances, else a relief model of the globe without such a difference would show little more in the way of relief inequalities than the skin of an orange. For example, Mount Everest is only 1/2000 of the earth’s diameter. On an 18-inch globe, it is estimated, it would be represented by less than 1/100 of an inch. Thus the highest mountain in the world wouldn’t even show!
A map combines the qualities of a picture and a book. Elevations of mountains or depths in water are depicted by forms of shading. A town is indicated by a dot, a road or river by a line. Codes of color can be employed, and other conventions are customary. The mapmaker must exercise some choice in the matter of naming places. He has to decide whether to use an American form of a foreign town or its native name, or one recently changed as an expression of national self-determination. Koln or Cologne; Dublin or Baile Atha Cliath? Praha or Prague; Munchen or Munich? This grows even more complex if the alphabet used by the natives is not related to a European one. There seems to be quite an assortment of spellings for the names of places in Persia (itself called Iran), China, India and other oriental lands. Maps should, of course, be clear and uncrowded, and the mapmaker should decide at the outset which kinds of things he must emphasize.
Of course, since Mercator’s Atlas appeared in 1585, mapmaking has grown continuously more scientific and accurate. The modern era of discovery and exploration does not consist in the vague adventuring by land and by sea which in a large measure constituted discovery up to the time of Captain Cook-and in some parts of the world long after that time. Today’s cartographers have precision instruments and theoretical knowledge far beyond any then in use. Mapping by airplane, for instance, is one of the newest and most popular methods giving access to hitherto inaccessible places. Telegraph, cable, radio, weather bureau and countless similar services have simplified the work of mapmakers and at the same time have given them far greater responsibilities. There is so much less excuse for them to be other than strictly reliable.
The modern mapmaker is an expert and his results go to experts whereas the early seafarer was more of a rough and ready adventurer who took a long chance hoping for gain, and did not care too much if he lost. By the old methods and equipment much of the world was discovered by accident. Desire for trade and wealth, missionary zeal, piracy, or sheer adventurousness were the usual reasons for exploration. In those times an explorer would ask for a little money to find a land that one could see and profit by. Today explorers like Roy Chapman Andrews require a quarter of a million dollars to explore a portion of the Gobi desert for knowledge of a world buried millions of years ago; not for financial profit in any way but for study of rocks and skeletons to reveal the beginnings of life on earth. It has been pointed out that while Columbus spent only about $2,000 to discover America, Byrd needed over $1,000,000 to enter the Antarctic. He spent nearly $200,000 merely to make a 17-hour trip over the North Polar Sea by air. Few modern explorers are able to take a large scientific staff into the field under a cost of $100,000.
When explorers have mapped the surface of the earth, will the job of mapmaker be finished? By no means. The whole idea has expanded and will continue to do so, for map making means many things to many people. Alexander von Humboldt, for instance, was puzzled by the fact that London was farther north than New York and yet was warmer in winter, while other places in the same latitudes varied in temperature. He began to plot new lines on the map running through places having the same temperatures, just as each line of latitude runs through all places of like distance from the equator. The temperature lines ran zigzag all over the map. He called them isotherms, and today no student of geography can do without his isothermic map. He followed this up with many other queries about the climate, and from his extended travels in South America and elsewhere he remembered certain facts. The height above sea level counts in climate, he knew from some of his own exciting mountain climbs. Mountains affect the rainfall too, he recalled. In his marvelous book, “Cosmos,” the science of physical geography was born, and Humboldt showed us a new way to look at ourselves and our earth.
Following the work of Humboldt and others, Joseph Henry gave us the daily weather map with its high and low-pressure regions and other data. Again, four-fifths of the earth is under water and this is a great field for investigators. Years ago, Lieutenant Maury of the U.S. Navy devoted his life to describing and mapping the sea – its currents, winds, temperatures, depths and many other qualities. Through him, the father of oceanography, navigators can take advantage of the most favorable winds and currents and many other benefits. Other types of explorers, like William Beebe, map the land of the fish, the actual depth and bottom of the sea, while Auguste Piccard did the opposite and soared 10 miles into the stratosphere. John Milne investigated the inside of the earth-the causes of earthquakes, and improved the seismograph which gives warning of impending disasters of this kind. And so today we still live in an age of discovery, and the vague notions of far-off countries give way to the most precise records. Accurate measurements of distances, heights, weather conditions, geological conditions; productive regions of the earth-its oil, minerals, wheat and other economic resources; plant life, animal life, human distribution, wealth maps, health maps-all these open fields of interest, work and achievement.
A basic necessity for compiling up-to-date maps is the collection and analysis of geographic and economic data. Several hundred thousand maps, charts, geographical reports, statistical records, post office guides, survey and exploration reports, historical notes and handbooks from all parts of the world are available for intensive study and research carried on by cartographers. All this research, traveling, surveying, compiling and drawing are essential to the production of the modern map. And today changing conditions make other maps of vital importance. One long-established concern publishing maps is in touch with all foreign governments through a branch office in Washington which contacts all the embassies. They consider a man in their cartography department an apprentice for the first three or four years of service which will give you a clue to the difficulty and importance of this type of work. New or old, maps and mapmaking are powerfully fascinating, bringing the world of war and work, peace and plenty, romance and reality, before our very eyes in a glowing panorama of adventure.
