was noiseless shattering of the huge
pile, The column parted, slowly at
first, the sections following one another
with increasing rapidity and crushing
the pedestal into nothingness. Where
the shaft had stood a fleecy cloud hid
the water, as If the great white
column had in a twinkle resolved into
dust, Around the edges came the bub-
ling yellow, the encircling waves car
rying the discoloration to a white radi-
I us. Only a moment the white cloud
hung over the spot and the magnificent
vision was thing OF the past.
In the opinion of Contractor Rudolph
Amman, as well as Of those who looked
on, the explosion yesterday was
greater success than the one that de-
stroyed the first Shag Rock, and when
soundlngs are taken this morning it is
expected that a depth of fully thirty
feet will be found The provisions of
the contract with the government re-
quire that a depth Of at least thirty
feet of low water shall exist where the
rocks stood. In the case of Shag Rock
No, l, which portruded its head ten feet
above the surface, the nine tons of
nitro-gelatine cleared away the rock to
depth of over twenty feet below the
surface at the beginning, it is conf
IDENTIFY believed that the required depth
has been attained by the explosion of
the ten tons of nitro gelatine.
In order to remove the 1900 cubic
yards Of matter which was composed
of hard sand stone, mixed with quartz
and having sub~strata of basalt, it was
necessary to place 1870 charges of nitro
gelatine in position, and to these 300
fuses We're connected by Electrical En-
glneer Frank Broili and his assistant,
G. B. Blanchard The explosive Is sew
en- or eight times as powerful as black
powder and Is insoluble. 1t was low
cred to the top of the rock in bags and
placed systematically In crevices over
the summit the fine weather of the last
few days aiding materially in the diff
cult work. The last charge was put
into position at o'clock Tuesday night
and all the charges were given double
cap. Yesterday morng the final work
of the electrical engineers was accomp-
lished, Contractor AXman having deter
mined the previous evening the explo-
noon or early in the afternoon. Less
publicity had been given to the event
than to the previous one, but hundreds
OF people had secured points of vantage
for the sight and waited patiently until
the explosion took place.
The tug Lottie removed the mast and
lighter from over the rock early in the
afternoon, the cable connecting with
the nitro-gelatine being attached to the
lighter. Five minutes before the explo-
sive was ignited the Lottie blew long
blast Of her wistle, another blast was
blown four minutes later and sixty sec
geyser was sent skyward. The charges
were fired by a small dynamo on the
lighter operated by four men.
Following the descent of the column
of water, small boats made haste to
reach the dscolored water in quest of
fish. Many rock cod, perch, sardines
and fish of other varieties We're picked
up, perhaps the finest specimen being a
sea bass.
AS soon as contractor Amman ia as
sured of sufficient depth of water over
the rock he will begin operations on
Arch Rock, the most notable of the re-
naming obstacles in the bay. While
only $500 cubic yards of Shag Rock No.
l and 5000 cubic yards of Shag Rock
No. have to be removed there are
$4,000 cubic yards of Arch Rock which
will be removed in order to give a
depth over the rock of thirty feet at
low water.-San Francisco Chronicle.
