rprising how
often this mode of occurrence will be found to obtain. But I cannot too
strongly caution the prospector not to trust to theory but to prove his
lode and his metal by following it down on the underlie. "Stick to your
gold" is an excellent motto. As a general thing it is only when the
lode has been proved by an underlie shaft to water level and explored by
driving on its course for a reasonable distance that one need begin to
think of vertical shafts and the scientific laying out of the mine.
A first prospecting shaft need not usually be more than 5 ft. by 3 ft.
or even 5 ft. by 2 ft. 6 in., particularly in dry country. One may often
see in hard country stupid fellows wasting time, labour, and explosives
in sinking huge excavations as much as 10 ft. by 8 ft. in solid rock,
sometimes following down 6 inches of quartz.
When your shaft is sunk a few feet, you should begin to log up the top
for at least 3 ft. or 4 ft., so as to get a tip for your "mullock"
and lode stuff. This is done by getting a number of logs, say 6 inches
diameter, lay one 7 ft. log on each side of your shaft, cut two notches
in it 6 ft. apart opposite the ends of the shaft, lay across it a 5 ft.
log similarly notched, so making a frame like a large Oxford picture
frame. Continue this by piling one set above another till the desired
height is attained, and on the top construct a rough platform and erect
your windlass. If you have an iron handle and axle I need not tell
you how to set up a windlass, but where timber is scarce you may put
together the winding appliance described in the chapter headed "Rules of
Thumb."
If you have "struck it rich" you will have the pleasure of seeing your
primitive windlass grow to a "whip," a "whim," and eventually to a
big powerful engine, with its huge drum and Eiffel tower-like "poppet
heads," or "derrick," with their great spindle pulley wheels revolving
at dizzy speed high in air.
"How shall I know if I have payable gold so as to save time and trouble
in sinking?" says the novice. Truly it is a most important part of the
prospector's art, whether he be searching for alluvial or reef gold,
stream or lode tin, copper, or other valuable metal.
I presume you know gold when you see it?
If you don't, and the doubtful particle is coarse enough, take a needle
and stick the point into the questionable specimen. If gold the steel
point will readily prick it; if pyrites or yellow mica the point will
glan
