Dotting these regions are the geographic North and South Poles, the geomagnetic poles, the principal magnetic dip poles where free awing magnetized needles point straight down or up, and clusters of minor magnetic poles. Best known, of course, are the North and South Poles, the ends of the imaginary axis on which the earth spins, the National Geographic Society says. The geomagnetic north and south poles represent the terminals of a line running through a hypothetical magnet near the earth's center. The axis is tilted about 12 degrees from that of the geographic poles. The north geomagnetic pole is near Thule, Greenland, and the south is in Antarctica, 791 miles from the South Pole. The geographical and- geomagnetic poles are fixed points. The actual magnetic poles, however, wan der about according to changes in the earth's magnetic field. They seem to drift about the Canadian Arctic and the South Pacific near Antarctica without any known pattern of move ment. These poles are not even directly op posite each other. Ten years ago, the magnetic north pole was on the northwest edge of Prince of Wales Is land in the Canadian Arctic. Since then, the pole has advanced northward across 60-mile-wide Barrow Strait to southern Bathurst Is land. . The magnetic poles exist because the earth itself is a huge magnet surrounded by a mag netic field. The field is made up of invisible lines of force running roughly north and south. These lines can be pictured as billions of little wires, arching outward at the Equator but bending back to the earth's surface in both hemispheres. Some lines loop far above the earth in equatorial regions and enter the earth near the poles. The areas where these lines enter or leave the earth vertically are the magnetic, or dip, poles. Thus the magnetic field is vertical, and free-swinging magnetic needles point down or up. This explains why an ordinary compass is useless in polar regions. Because the earth's magetism Is irregular, the lines of force do not strike the earth's surface at a single point. So there are clusters of minor magnetic poles. Curiously, the north magnetic pole's cluster forms an ellipse; the south'! a circle. About 100 permanent observatories around the world, many temporary stations, and spe cifically equipped airplanes constantly meas ure the earth's magnetic fields. Using the data gathered, scientists known as magneticians periodically bring world charts up to date. Navigators use the charts to determine how far from true north their compasses vary at different locations. Hidden deposits of mag netic material, such as iron ore, also may af fect a compass. The earth's magnetism varies in the course of time. In the middle latitudes, electrical cur rents high in the atmosphere cause changes of about one-fifth a degree between morning and afternoon. Forces deep within the earth cause changes in compass direction which may amount to 30 degrees or more over two or three centuries. Ask Andy Aardvark Has No Relatives Andy sends a complete, 20 volume set of the World Book Encyclopedia to Patty Jen kins, 15, of Washington, III., for her question: ARE THERE AARDVARKS IN CAPTIVITY? This fellow was discovered by the Dutch who settled South Africa and he was like no ani mal they had ever seen. The scientists thought that he was related to the anteater of South America, but they have since changed their minds. They now agree with the Dutch settlers. The aardvark is like no other animal in the world. The Dutch settlers of South Africa gave this unique animal its name which means earth-pig. True, he burrows in the earth sometimes faster than a person can dig him out. True, he has some pig-like features. His coarse, thick skin is covered with short bristles, he has a long- pig-type snout and he grunts. But here the likeness ends. The aardvark may be 6-feel long and a long tapering tail makes up about a third of this length. He stands on short, stubby legs and his spine arches up in a high hump. His head is crowned with a pair of mule type ears and his eyes are capped with dropping lids. He lives on a diet of ants and ter mites and in character the aardvark is one of the shyest of all animals. It is not easy to keep the strange fellow in captivity. The termites on which he feeds build nests of hardened mud five or six feet high and these busy builders are plentiful in the wilds of Africa. It is not easy to supply a captive aard vark with his natural food. What's more, he is a fast and skillful burrower. Unless he is trapped in a very sturdy home, the aardvark soon digs his way out of captivity. But these needs have been met and many aardvarks have been kept in captivity. How ever, the early Dutch settlers of South Africa soon found that their strange native animal was a disappointing zoo member. They could capture him and meet his food and housing needs. But the aardvark refused to go on display. First, the aardvark tended to keep out of sight. What's more, he avoided the daylight. In the wild state he spends the day dozing underground and comes out to do his foraging after dark. Zoologists classify the aard vark in an order all his own. Andy awards each day a full net of tha World Book Encyclopedia for the flrat queitlon ha lelecta to answer. When a gecond ques tion la answered a large world globe or atlas Is awarded. Ques Uons are accepted from teenage or less-than-teen-age readers. They should be addressed to the Register-Guard, 97ft High St., Eugene. Andy prefers that questions be written on postcards, rather than In letter form. However, the South African aardvark is not quite unique for he has a close cousin in Northeast Africa. They are classified as two species of the same family and the same or derand they have no other relatives in the world. e Andy sends a Hammond's Library World Atlas to Jimmy J,a Barbera,, JO, of Brook field, Wis., for his question: WHERE IS MICRONESIA? The name of this place means the Little Islands but there is far more water in it than land. Micronesia is a vast area of the Pacific Ocean stretching east ward from the Philippines. There are more than 2,500 little islands separated by these dreamy, tropical waters. The Marshall! and the Marianas, the Gilberts and the Carolines are clusters of Micronesian Islands. Wake Island is one of tha lone isles of Micronesia. In the whole of Micronesia there is about 1,400 square miles of dry land. The islands would fit into about one fiftieth part of the state of Wisconsin. Some are low coral islands, some are humps of old volcanoes and most of them have less than half a square mile of land. Weather Extremes In Bahia Felix, Chile, rain falls an average of 325 days a year. But Iquique, Chile, farther north, once went 14 years with out any rain at all, To Your Good Health Milk Diet Termed Inferior By DH. JOSEPH G. MOLNER Dear Dr. Molner: I am on a milk diet. Raw milk is rather hard to get, so instead of the pasteurized variety, would you recommend buttermilk from a dairy? MRS. E. M. Pasteurization was adopted because it prevents so many diseases, such as undulant fever, tuberculosis and typhoid fever. These and others have been traced to milk that became con taminated, either because of disease in cattle, or some other source. Pasteurization doesn't change the nutritional value of milk. It simply destroys germs. Raw milk is dangerous. Don't take a chance. I don't suppose I can quibble with people who insist on trying a milk diet. It is not as good as balanced one of elements which milk alone cannot provide. Drink buttermilk if you pre fer. But it also requires pasteur ization. Dear Doctor: Is it all right to drink milk with your meal? Someone tells me that one should drink only water with the meal, and milk after wards. Is this true? MRS. E. D., JR, "Someone." T rpprAt in av U trying to foist off on you an old Wives' tale. There's nn rrauin why you shouldn't drink milk wun your meals. Dear Dr. Molner: What causes my ears to ring? I am not bothered with wax R.R. There are several causes other than wax. I've had so many in quiries on the subject that I ve rounded things up in a booklet called "Ear Noises: Their Causes and Cures." To receive -a copy, send ten cents in coin for print ing and handling costs, and a stamped, self-addressed enve lope. Just write to me in care of this newspaper and ask for "Ear Noises. Dear Dr. Molner: Would eating half a grapefruit after each meal aggravate ar thritis? B.D.R. No. Dear Dr. Molner: What is the average weight for a girl, barely 11, who is 4 feet 9Vt inches tall and weighs 89 pounds. She doesn't look too heavy or fat except for a tum my or spare tire. She has never lost her baby tummy. Should she diet? MRS. M.T. She's slightly above average in height and weight for her age. Part of her "tummy" may be poor posture. She undoubt edly will "streamline" at puber ty. Does she get plenty of ex ercise? I'd doubt if any reducing is necessary. About 2,000 calories a day are normal for a child of her age and size.
