They then wanted to gather the gold, and Marshall threatened to shoot them if they attempted it; but these men had sense enough to know that if "placer"-gold existed at Coloma, it would also be found farther down-stream, and they gradually "prospected" until they reached Mormon Island, fifteen miles below, where they discovered one of the richest placers on earth.

These men revealed the fact to some other Mormons who were employed by Captain Sutter at a grist-mill he was building still lower down the American Fork, and six miles above his fort.

All of them struck for higher wages, to which Sutter yielded, until they asked ten dollars a day, which he refused, and the two mills on which he had spent so much money were never built, and fell into decay.
In my opinion, when the Mormons were driven from Nauvoo, Illinois, in 1844, they cast about for a land where they would not be disturbed again, and fixed on California.

In the year 1845 a ship, the Brooklyn, sailed from New York for California, with a colony of Mormons, of which Sam Brannan was the leader, and we found them there on our arrival in January, 1847.

When General Kearney, at Fort Leavenworth, was collecting volunteers early in 1846, for the Mexican War, he, through the instrumentality of Captain James Allen, brother to our quartermaster, General Robert Allen, raised the battalion of Mormons at Kanesville, Iowa, now Council Bluffs, on the express understanding that it would facilitate their migration to California.
