and clear skies has at last come, and the
miners are improving it with great en-
ergy. More companies are washingnow
than at any other time for several months.
Water is everywhere abundant, and will
continue so, in places where the supply
is never permanent, to much later
period than usual. There has not been
much cleaning up done so far, as our
fine weather is but few days old; but
the following yields are full of promise.
SAN JUAN HILL-The last run of
the Bloomer Company yielded sl,927.
These claims are filled with very large
boulders, which have to be blasted and
the fragments hoisted out by derrick.
The Ohio Company cleaned up this
week 81 200; and the Knickerbocker
Company, from dirt fifty or sixty feet
above the bedrock, realized $500. Lowe
& Co. raised shaft from their tunnel
and found dirt which prospects over an
ounce to the pan! Such a prospect is
unprecedented in these diggings, and
goes far to confirm the opinion that there
is lead of great richness running
through the hill. Persons reading this
who are not familiar with the nature of
the mines hereabouts, must bear in
mind that the rich yields for which
North San Juan is famoas have mostly
been made by washing immense quanti-
ties of dirt which, usually, when pros
pected with pan, does not yield more
than the color. If we e,er get to wash
ing through rich lead, there will be
yields on this hill that will astonish the
whole State. An interest in the Brit
annia claims belonging to the estate of
Michael Craddock was sold lately for
$3.50. A very large amount of water
is now used on this hill. When the hy-
draulic process was first introduced there
was seldom a larger head than from
twelve to twenty inches used in any
claim. Now single company, the Sail
OF Boys, employ two hundred inches,
and several others from one hundred and
twenty or thirty to one hundred and fif-
ty inches. Such streams as these di-
vided between two pipes and having
pressure of from one hundred to one
hundred and fifty feet, dash with tre-
mendous force against the banks of earth,
the hardest Of which must yield to their
influence.
JUNCTION BLUFF.-The Palmer
claims lately yielded s7Oo, from run
made on first opening. The McKeeby
ground is still giving out The propri-
etors this week got prospects of $40 to
the pan.
SwEETLAND.-A single item from
this place: The Kentucky Company
have cleaned up $500.
MoNTEzUMA.-The keystone Com
pany, from one weeks work of two
men, realized ST 400.
MANzANITA HILL-Wateri in abund-
ance. Snow FIVE inches deep at this
date April l1th. The different COM
panies are all in successful operation.
The New York Go. cleaned up last week
eleven hundred dollars, after. run of
nine days and a half-clearing about
twenty dollars per day above expenses.
The same company are running now
night and day, the object being to pro-
tect their sluices. from robbery. Another
consideration is, that water is furnished
for night work much cheaper than the
ordinary rates. These claims are now
valued at S. 900 share, and are cheap
at that. Vanita recently sold his inter
est on Dutch Hill for 50 900 cash. This
is considered a good trade from the fact
that the ground is nearly worked out.
The New York Company had stolen from
their tunnel lately two tanks Of quick
silver. Some of the San Juan slight
o hand gentry are around.

BRANDY CITY.-This fourishing
mining locality is situated on the north
bank of the North Yuba, in Sierra
county, about six miles from Campton-
vile and fourteen from San Juan. The
