It was important to keep the discovery as quiet as possible. Searching along the dry channel Sutter and Marshall found more of the gold flakes. In some places the yellow scales were very plentiful, and seemed to promise that large quantities of the valuable mineral could be found near at hand. It was impossible, however, to keep the news from the workmen who had helped in finding the flakes. Before long the news spread, and in March, 1848, two newspapers of California mentioned the discovery on the south fork of the American River.

The country was so sparsely settled, and life so primitive, that no great excitement was caused by this news for some months. But in May a Mormon, coming from the settlement of Coloma to San Francisco, walked down the main street waving a bottle filled with gold-dust and shouting "Gold! Gold! Gold from the American River!"

His words, and the sight of the glittering bottle, caused tremendous excitement in San Francisco, and in the twinkling of an eye men took possession of sailboats, sloops, launches, any kind of craft, and started up the Sacramento River. Those who could not get boats to take the quicker course hurried off on horses or mules, in wagons or on foot. It was like a fairy tale. The seaport town of San Francisco, which had been well filled, was practically deserted overnight. Shopkeepers closed their stores, families hurried from their houses, and every class of people pushed toward the American River. The roads that led thither, which had usually been almost as empty as the prairies, were now filled with a wildly rushing throng. A man who had crossed the Strait of Carquines in April was the only passenger on the ferry, but when he returned two weeks later he found two hundred wagons trying to drive on board the ferry-boat.

Business on the coast came to a standstill. The newspapers that had been started stopped publication. The churches closed, and all the town officers deserted their posts. As soon as a ship touched the coast and the crew heard of the finding of gold they deserted, and the captain and mates, seeing themselves without a crew, usually dashed after the others. Empty vessels lay at the docks. A large ship belonging to the Hudson's Bay Company, which had put into San Francisco harbor, was in charge of the captain's wife, every one else having left for the gold fields. Prices in all the country from San Francisco to Los Angeles jumped prodigiously. If men were to stay at their work they demanded and received twice their former wages. Shovels and spades sold for ten dollars apiece. They, and a few other mining implements, were the only things still manufactured. The cry of gold had turned men's heads like the magic wand of some fairy.

Inland California presented a strange sight. The roads that ran from San Francisco to Sutter's Fort had formerly lain between prosperous farm lands, but now the crops were going to waste, the houses were empty, and the cattle free to wander through fields of grain. Along the American River, on the other hand, hills and valleys were filled with sheltering tents, and huts built of brush and rocks thrown together in a hurry. Men could not stop for comfort, but worked all day on the river bank. There were almost as many ways of searching for the gold as there were men. Some tried to wash the sand and gravel in pans; some used closely woven Indian baskets; some used what were called cradles. The cradle was a basket six or eight feet long, mounted on rockers, and open at one end; at the other end was a coarse screen sieve. Cleats were nailed across the bottom of the cradle. One workman would dig the gravel from the river bank, another carry it to the sieve, a third pour water over it, and a fourth rock the cradle The screen separated the stones from the gravel, the water washed away the earth and carried the heavier soil out of the cradle, thus leaving the black sand filled with the gold. This was later carried to a pan and dried in the sun. The sand could then be blown away, and the gold would be left.

Men knew that fortunes were to be found here. On a creek a few miles below Coloma, seventeen thousand dollars' worth of gold was taken from a ditch three hundred feet long, four wide, and two deep. Another small channel had yielded no less than twelve thousand dollars. Many men already had bags and bottles that held thousands of dollars' worth of the precious mineral. One man, who had been able to get fifty Indians to work for him as washers, obtained sixteen thousand dollars from a small creek in five weeks' time.

All this quickly changed the character of upper California. Every man wanted to be a miner, and no longer a cattleman or farmer, as before. It looked as though the towns would shrivel up, because of the tremendously high wages demanded by the men who were needed there. Cooks in San Francisco were paid three hundred dollars a month, and all kinds of mechanics secured wages of fifteen or twenty dollars a day. The forts found it impossible to keep soldiers on duty. As soon as men were paid off they rushed to the American River. Sailors deserted as fast as they could, and the American war-ships that came to anchor off Monterey did not dare to allow a single man to land. Threats of punishment or offers of reward had no influence over the sailors. They all felt certain they could make fortunes in a month at the gold fields.

Soon men began to wonder whether they could not duplicate in other places the discovery that Marshall had made on Sutter's land. Wherever there was a river or stream explorers began to dig. They were well rewarded. Rich placers of gold were found along the course of almost all the streams that flowed to the Feather and San Joaquin Rivers. Along the course of the Stanislaus and Toulumne Rivers was another field for mining. By midsummer of 1848 settlers in southern California were pouring north in thousands, and by October at least ten thousand men were washing and screening the soil of river banks.
