In 1845 Juan Manso and Andrés Pico leased the Mission at a rental of $1120, the affairs having been fairly well administered by Padre Orday after its return to the control of the friars. A year later it was sold by Pio Pico, under the order of the assembly, for $14,000, to Eulogio Célis, whose title was afterwards confirmed by the courts. Orday remained as pastor until May, 1847, and was San Fernando's last minister under the Franciscans.
In 1847 San Fernando again heard the alarm of war. Frémont and his battalion reached here in January, and remained until the signing of the treaty of Cahuenga, which closed all serious hostilities against the United States in its conquest of California.
Connected with the Mission of San Fernando is the first discovery of California gold. Eight years before the great days of '49 Francisco Lopez, the mayordomo of the Mission, was in the canyon of San Feliciano, which is about eight miles westerly from the present town of Newhall, and according to Don Abel Stearns, "with a companion, while in search of some stray horses, about midday stopped under some trees and tied their horses to feed. While resting in the shade, Lopez with his sheath knife dug up some wild onions, and in the dirt discovered a piece of gold. Searching further, he found more. On his return to town he showed these pieces to his friends, who at once declared there must be a placer of gold there."
Then the rush began. As soon as the people in Los Angeles and Santa Barbara heard of it, they flocked to the new "gold fields" in hundreds. And the first California gold dust ever coined at the government mint at Philadelphia came from these mines. It was taken around Cape Horn in a sailing-vessel by Alfred Robinson, the translator of Boscana's Indians of California, and consisted of 18.34 ounces, and made $344.75, or over $19 to the ounce.
Davis says that in the first two years after the discovery not less than from $80,000 to $100,000 was gathered. Don Antonio Coronel, with three Indian laborers, in 1842, took out $600 worth of dust in two months.
Water being scarce, the methods of washing the gravel were both crude and wasteful. And it is interesting to note that the first gold "pans" were bateas, or bowl-shaped Indian baskets.
The church at San Fernando is in a completely ruined condition. It stands southwest to northeast. The entrance is at the southwest end and the altar at the northeast. There is also a side entrance at the east, with a half-circular arch, sloping into a larger arch inside, with a flat top and rounded upper corners. The thickness of the walls allows the working out of various styles in these outer and inner arches that is curious and interesting. They reveal the individuality of the builder, and as they are all structural and pleasing, they afford a wonderful example of variety in adapting the arch to its necessary functions.
