Cruiser Maryland Remains In
Harbor Until Needed To Tow
Submarine Again ~
(From Saturday Advertiser,)


No ship, dredge or scow was an
ahored near the grave Of the F-4 last
night. After the last line holding her
had parted, the cruiser Maryland re-
turned to the naval dock; the tender
Alert is anchored east Of the channel
near the shore, and the ldredge Gay
ord and remaining scow were brought
in. The Maryland left her anchorage
lbcut two clock yesterday afternoon,
The three submarines left the naval
ilip to make place for her to enter,
returning later. N-..I%A.
Today will be devoted to working on
he new cables, each of which will have
ninety feet of two and one-half inch
chain in the center. This Is expected
to endure chatting, which has broken
line after line. ,.- ~ .
Air Compressor Requisitioned Asse,
An engine and air compressor will
80 brought from Pearl Harbor and
placed on the Gaylord. The air will
be used to try to force water out OF
the submarine.
hIf the openings in the hull are low,
we should be able to reduce her weight
considerably by forcing out water,
said Lieut.. Comdr. J. A, Furer, naval
constructor. eve would have an air
cushion at the top and maintain pres
sure in excess of that of the water
at the submarines depth. If the open
ings are high in her hull, we will have
little success, for the air and not the
water would escape from the hull. We
cannot know what will be the result
Of the plan until we try it out. ~ ~
Lieutenant Commander Furer was
asked what would be the next plan If
this failed. He said he could make no
prediction. -f4 'z@...,
Scows Can Raise Craft n5.,. IN
He believes, however, that his seows
are able to raise the submarine, and
that they have raised her some thirty
feet in all. w." ~ I'm. ".
''I have worked out displacement
curves of the scows, /" he said. There
are marks on each corner. When we
had the weight Of the submarine, these
marks showed that she was bearing
about 275 tons more weight than be-
fore we started. / consider that con.
elusive proof that the submarine was
clear of the floor, Dragging the F-4
over the bottom would be out Of the
question. Whatever gain we have made
)r will make win be when she is clear.
\ 17,000-pound anchor holds the Mary
and; certainly a 260-ton anchor, such
as the submarine really is, would hold
anything. Her keels would drag over
the sand and bite in as an anchor does
We have had her of the bottom,
Tomorrow is set as the earliest prob
lble date for the completion of one of
the new lines. Dragging is expected
to begin at once thereafter. -, IN.
Maryland Remains Inside r. A.
The Maryland will remain within the
harbor until she is needed again for
towing the submarine. Finishing the
lines, placing them about the F-4,
transferring them TO the seows, pre-
pairing the mir compressor and engine
and sending the divers down to affix
hose to the salvage valve will have
to be done before the cruiser can be
Of use again.
With the exceptions of having the
submarine buoyed, marking her loca-
ton, and of having salvage equipment
that was not possessed when the F-4
was lost, operations have fallen back
o where they began. Experience has
been valuable, however, and all are
qualified better to handle the work
than they were. They have learned
what can be done and what cannot be
done; they have learned how to guard
| against different mishaps. g.s-r1.
The Alert is nearer shore than she
has been since the submarine was lost.
She went out in the afternoon Of March
%, and since that time has been an.
'hOred almost two niles from shore.
Useless Material Removed
A boom was removed from the dTedge
Gaylord yesterday, under the direction
If Fred Buss. He had it placed when
he naval officers expected to use the
living bell, which has been discarded,
making the boom useless. Other work
IN the dredge, such as removing use.
'ess material, also was being done yes,
| terday. ,.. s,
The line that broke at nine O clock
Thursday night was the weakest of
the four. 1t was thought to have part.
d before, but it was found still TO be
asst when strain was put upon il.
No one will hazard guess as to
when the submarine will be lifted, He
5 hardy, indeed, who win predict from
me dav to another. 1t appears, how.
ever, that success will come only after
weeks, perhaps longer, of efforts, at
'endcd probably by disappOintments as
great as those that have gone before.
No one knows what new problems may
be met: but it is believed that the
worst have been solved.
