CONsTANTINoPLE, November I'll
The destruction a few days ago of a
British submarine of the cruiser"
class was due largely to the fact that
on captured French submarine. the
Turquoise, were found certain secret
instructions concerning the operations
of the allied submarine fleet in the Sea
of Marmora. These documents, be-
sides naming the Marmora coast
points where supplies could be OBJ
tanned by the allied submarines. also
threw light on the movements of
these vessels. In pursuance of the in
formation thus obtained, the German
submarine U. B. IA waylaid the Brit
ish undersea Cruiser" and sent
torpedo into her side. Twenty-four
men were drowned. while the crafts
three officers and another five of the
crew, most of them wounded, were
made prisoners.
That the allied submarines in the
Marmora were being supplied with
necessities in the lake itself had been
tiles for some time. 1t had been i'm
possible. however, to obtain accu-
rate information. Since it was felt
that an end had to be put to this

ment declared the entire Marmora
coast CLOSED zone," into which no
ship of any sort could venture with
out special permit and representa-
tive of the Ottoman marine depart
ment aboard. Nevertheless. a large
number of Greeks, in some cases also
Turks. ventured into the forbidden
waters. Heavy sentences of penal
lservitude. in some instances terms of
eight years. were imposed upon them.
Notwithstanding this the traffic con-
tinued until quite recently.
Use Coal as Fuel.
! The papers found on the Turquoise
show also that the newer and larger
types Of British submarines use coal as
fuel. In the list of bases" in the Mar
mora sea are several places where coal
could be obtained. Turkish patrol
boats had reported that they had seen
submarines from whose tunnels coal
smoke issued. At the time this was not
| believed. 1t has been learned since
, then that the principles of locomotion,
above and below the surface. remain
the same, with the difference that the
su brnarine SO obtaining its power must,
while in the zone of the enemy. re-
plenish its electric storage batteries
at night, when nothing but sparks from
the funnel could reveal it's presence.
| In connection with the efforts of the
Turkish authorities to restrict mill
| tary activity on the Sea of Marmora, a
rather amusing incident occurred last
July. The officers of a certain German
submarine were in the habit of dining
at one of Pera's best hotels. So did the
officers Of an English submarine on at
| least one occasion. At that time the
Turkish government, as 1t does even
today. permitted the subjects of hos
tile governments to move freely about
Constantinople. Dining one day at this

marine was given by the waiter let
ter which bore his full name and ad-
| dress. The waiter said that on the
previous evening the letter had been
| left by party of five, one of whom
seemed to be an American.
Greetings From British.
The letter contained greetings from
the officers of the British submarine
to the officers of the German subma-
rine. 1t was couched In friendly terms,
showing further that the sponsors OF
| the letter were of sportive turn of
mind. They would meet some day.

Whether the waiter was right in his
assertion that an American had been
in the party is hard to say. At any
| rate. the Turkish government began to
keep close watch on the United States

Kabatash. Turkish motor boats pa

| while at the jetty, which the crew and
visitors of the Scorpion had to use, po-
lice officials inquired closely into the
purpose of every trip to or from the
vessel. A little later the Turkish gov
ernment, on the plea that the moorings
of the Scorpion were no longer safe,
| insisted that the vessel take new
station in the Golden Horn, beyond
the new and old bridges, at e. point
