Gold endures, it never tarnishes or rusts, and the gold dug up thousands of years ago is still circulating. Mrs. Allen surmises that if all the gold ever mined were put into a single cube it would fit into a baseball diamond 90 feet square. She traces the history of gold from the Stone Age, through all the major gold rushes. amiliar as it is, gold has had an exotic past in every country of the world. The largest nugget ever found was in Australia, on a muddy road, and weighed 200 pounds and was literally worth its weight in- $4,200,000. Today, at the largest gold mine in the States, one tone of ore has to be blasted, crushed and processed to get three tenths of an ounce of gold, an amount ""no larger than the tip of your little finger."" This mine's lowest level is 5,200 feet down ad has a temperature of 113Â° Fahrenheit.) Mrs. Allen's subject has a natural allure; after a hundred pages you get tchy fingers.
