rne first thing TO do is 10 ex anime the
gravel and bouliers Of the mountain
streams and note carefully the structure,
character of the gravel sash. This will
reveal the geological formations that are
intersected by the streams. Try the sand

up the stream until the geological zone ~
found that has produced the quartz or
other mineral bearing rock. Then follow
the supposed mineral bearing zone on ,s
line. and make especially careful exam.

difference III the opposite walls Of the
the vein. Then follow il on the line Of

where the best ores are seen, 40 as TO de-
termine the position vi ,he best ore chutes
before making any location on the LODI.
The first work should consist Ut shallow

small trench along the line Of outcrop is
preferable. II the surface is stationery

the requirements of the laws OF the I'm
