There is a vast difference between the way in which the precious metal is now extracted and the primitive methods which were considered perfect in the earlier part of the century. The miner of fifty years ago never dreamt of machinery, costly and magnificent, capable of crushing thousands of tons of quartz per week. He 'dollied,' or ground, his little bits of rock by means of a contrivance resembling a pestle and mortar, and it was only the very richest stone that repaid him for his labour. In fact, there was very little crushing in those days, quartz not being easily found sufficiently rich to make such work a paying concern, and it was therefore alluvial gold which was chiefly sought for. The gold-seeker having decided on the place where he was to make his first venture, provided himself with a shovel and pick and started for the 'diggings.' Gold-mining was then carried on all over California, and he had his choice of many camps. [Illustration: The Hand-cradle Method of extracting Gold.] But what a wild and lawless place was California in those days! Here in these gold-fields were gathered together thousands of the greatest desperadoes that the earth could boast of, and thousands of needy, if harmless, adventurers from every country in the world. Fortunately with them were mixed thousands of honest hard-working men, of every condition in life, from the peer to the peasant, men who had been doing well, or fairly well, at their professions, or in their business offices at home, but for whom the attractions of this El Dorado had proved too powerful. Gold is perhaps the most widely and universally sought product of the earth's crust. In the very earliest writings which have come down to us gold is mentioned as an object of men's search, and as a commodity of extreme value for purposes of adornment and as a medium of exchange. The importance which it possessed in ancient times has certainly not lessened in our day. Without the enormous supplies of gold produced at about the time when the steam-engine was being brought into practical use it is difficult to imagine how our commerce could have attained its present proportions; and but for the rush of immigrants to the gold-fields in the beginning of the second half of this century Australia might have remained a mere convict settlement, California have become but a granary and vineyard, and the Transvaal an asylum of the Boers who were discontented with the Cape government.
