GRASS VALLEY, December :, 1851.
DEAR SIR: You ask my opinion of the Grass Valley
Quartz Mining Co.'s Mil Claims &c formerly Known az
A. Collins Co Is Model Mill have bsd charge Of the
mill, engineer since the mill was started fsome x
months and can confidently say this m csnable of
crushing more rock than mil in thu Valley This mill
has ten stamps but owing TO their Size the peculiar
construction OF its batteries will crush rosks with
onethrd less hands and half the power than other mills in
this town that have eighteen stamps
Our average for several weeks past has been
tons day, (of twenty hours per stamp this
has been that crashes easier than the yield
the mines Still have hesitation in saying crush
thirty tons per day with the rock properly PREPARED nom
any vein In this vicinity The comp have extensive
Ing from these hills during the past weeks and
yield from the former has been about hundred
dollars per ton, fem the latter about sixty The best
yield have had during this time has been two hundred
and forty taken out Of the
stamps besides three hundred dollars taken
out the batteries the tables reached
the smagam&tors. TLs would be five and half pounds
amslgam per stamp whcn would yield hundred dollars
per pound of gold The from these hllsis mostly
