This author states (Vol. 1, p. 489) that a vein of gold-bearing 

 quartz was worked near the Mission of San Fernando by M. Baric 

 in 1843. 



According to De Mofras, the gold of the San Francisquito Rancho 

 was fii*st explored by M. Charles Baric. He gives its distance in 

 Ihe mountains as six leagues to the northward of the Mission of 

 San Fernando, and fifteen leagues from Los Angeles. He further 

 states : "This vein has an extent of six leagues, following the direc- 

 tion of the ravine where it is situated. The gold is found near the 

 surface of the soil, and some pieces weighed two or three drachms." 

 This description would lead one to the opinion that the deposit was 

 a placer one and not a vein, although he uses the word filon.
