San Diego County is coming TO the front
rapidly as a mining regiOn. The great
gold resources OF it's eastern desert por-
tion are being rapidly prospected and ex-
plotted, and a number OF new desert mines
will be heard OF soon. Much interest Is
being taken in an extensive deposit or
kaolin OF unusual fineness and value near
El Cajon. Samples have been taken 10
Japan and pronounced equal 10 any in the
world. and similar judgment has been
pronounced by Eastern manufacturers OF
fine pottery. II is expected that Japan
will furnish the principal market Mines
