Now came the division of the 20,000 acres. A line was drawn across the middle; a coin was tossed up to decide which of the two should have the first choice, and fortune favoured the "snobs," who selected the northern half, called by the natives Burra Burra. To the southern part the "nobs" gave the name of "Princess Royal". The companies soon began operations; but though the two districts appeared on the surface to be of almost equal promise, yet, on being laid open, the Princess Royal was soon found to be in reality poor, while the Burra Burra mines provided fortunes for each of the fortunate "snobs". During the three years after their discovery they yielded copper to the value of L700,000. Miners were brought from England, and a town of about 5,000 inhabitants rapidly sprang into existence. The houses of the Cornish miners were of a peculiar kind. A creek runs through the district, with high precipitous banks of solid rock; into the face of these cliffs the miners cut large chambers to serve for dwellings; holes bored through the rock, and emerging upon the surface of the ground above, formed the chimneys, which were capped by small beer barrels instead of chimney-pots. The fronts of the houses were of weatherboard, in which doors were left; and for two miles along each side of the stream these primitive dwellings looked out upon the almost dry bed of the creek, which formed the main street of the village. Here the miners dwelt for years, until the waters rose one night into a foaming flood, which destroyed the houses and swept away several of their inhabitants. In 1845 Burra Burra was a lonely moor; in 1850 it was bustling with men, and noisy with the sounds of engines, pumps and forges. Acres of land were covered with the company's warehouses and offices, and the handsome residences of its officers; behind these there rose great mounds of blue, green, and dark-red ores of copper, worth enormous sums of money. Along the roads eight hundred teams, each consisting of eight bullocks, passed constantly to and fro, whilst scores of ships were employed in conveying the ore to England. From this great activity the whole community could not but derive the utmost benefit, and for a time South Australia had every prospect of taking the foremost place among the colonies.
