w naL tney Will md at the end or
the five-foot tunnel yet to be carved
is not known. Pneumatic hammers
cannot be brought to play in the
nianhole because OF the vibrations
they would set up.~
End IN CrawIway
The rescue shaft, engineers figure.
will terminate In the eighty-foot
cavern which Collins reported he had
discovered at the end Of his narrow
cawlway just before he was trapped
This would enable workmen to ap-
proach Collins feet and free them
from the boulder IL he is still pin
ioned by 1t without climbing over
his body as they would have had to
do, had the followed his own course
through the treacherous mouth of
Sand Cave.
The narrowness Of the bore pre-
vents more than one man at time
working. workmen expect to strike
within ten feet OF Collins. The COM
munique issued at 1916 haid:
Hard Limestone
Progress favorable but necessar.
lily somewhat slow, as rock encoun-
tered in drifting manhole from the
base Of the lateral heading into the
anticipated cavern Is very hard lime
stone approximately five feet thick.
''It is still believed that when
this hole Is made a close estimate
on the lime element can de made.
I'VE will be within ten feet OF
Collins. What obstacles may be en-
countered in this avenupe no one
can tell. but the nature of this
should be known before dark.
Progress through the manhole is
now one-man job, with hand tools
as pneumatic hammers cannot be
used on account of vibration.
Last sound tests made between
the cave-in in the original tunnel and
the facing of the tunnel verified
former tests much more nearer than
before"
Timbering Finished
At 10 a. m. today timbering OF the
shaft was finished and the pick and
shovel crews returned to the bottom.
Timbering operations had taken
more time than was expected.
At 1890 the bucket brought up
the first load of sandy-like material.
causing observers at the head of the
shaft to believe the crews at the
bottom had struck the anticipated
layer Of sandy material lying be-
tween them and the cavern.
The dry character OF this material
corresponded with the nature of the
rock geologlsts had expected to sur
round Collins prison.
Rapid progress was made duripg
the night. and Brig. Gen. A. e. Ke-
hoe. State adjutant general, said
early today, and the lateral shaft
branching from the base of the res
cue pit now extends thirteen feet
toward the cavern.
The lateral digging is being done
at an angle which will bring the
shaft to an end about six feet lower
than originally estimated.
The Official communique issued at
s o'clock reads:
"The progress in the lateral tun-
mel last night was very encouraging
and at distance of twelve feet from
the main shaft an attempt is being
made to break through the limestone
roof and drift vertically into the ave,
nue. tcavern), existence OF which was
determined from the core drill log.
Much trouble was encountered in
the last Ave feet of heading and falls
we're numerous. but 1t has been well
timbered and Is considered safe.
1T is felt that the most serious
obstacles have been surmounted
and that II Is now only question
of cubic yards and time until Col
Inns Ia reached"
