JUNE 12.] THE NEW ZEALAND GAZETTE. 1809

There is also a patrol vessel off White Stone at which
vessels passing that point will be required to stop upon
signal.
Variation.—10° W.

III. DELAWARE RIVER.

Net A 41 closes the channel of the Delaware River at Fort
Delaware.

Vessels desiring to pass in either direction must obtain
permission from the patrol-boats, which will be stationed
as follows :—

For incoming vessels, in the channel below Reedy Island.
For outgoing vessels, in the channel off New Castle.

Vessels approaching the patrol-boats must slow or stop
until identified, and must show their colours and the Inter-
national Code letters designating the name.

At night the signal to stop will be a red star fired by the
patrol-boat.

When the channel is clear for passage the station-ship off
Fort Delaware will show by day the signal T X B, and at
night a white light over a red light. This must not be taken
as a signal to proceed unless permission has first been given
by the patrol-boat.

Vessels must not steam at a speed greater than five knots
while passing between the patrol-boat stations as given above,
and while in the defensive sea area must steer an accurate
course well on New Castle range.

Masters of all vessels outward bound must, before sailing,
report to the District Intelligence Officer, Building No. 7,
Navy Yard, Philadelphia, for final instructions and permission
to proceed.

When reporting masters must bring with them all secret
or confidential publications for the purpose of checking the
list of the same.

They will be given a special recognition signal, which must
be flown from the time of getting under way until outside of
Delaware Bay.

IV. CHESAPEAKE BAY.

All defensive nets in Lower Chesapeake Bay have been
removed.

PANAMA.

PANAMA CANAL. — MIRAFLORES APPROACH. — BEACONS TEM-
PORARILY DISCONTINUED. — GAS-BUOY ESTABLISHED.

On account of dredging operations beacons 9 and 11, in
the approach to Miraflores Locks, have been temporarily
discontinued.

A gas-buoy with pyramidal superstructure, painted black,
showing an occulting white light every 2 seconds—thus, light
1 second, eclipse 1 second—will be maintained to mark the
edge of the navigable channel.

The channel will be permanently marked when dredging
operations are completed.

GAS-BUOY ESTABLISHED.

On 11th February, 1919, a gas-buoy was established to
mark the edge of the navigable channel in the southern ap-
proach to the Miraflores Locks. The gas-buoy is moored in
36 ft. at mean low water at the intersection of the range
formed by beacons 5 and 7 in line and the prolongation of
the centre line, west wing wall, Miraflores Locks.

CAUTION.—Mariners are cautioned to give this buoy a
berth of at least 75 ft. at low water or when the ranges west-
ward cannot be seen. Owing to the rise and fall of the tide
and the current produced by the tide, spilling of the lower
chamber, and the opening of the gates at Miraflores Locks,
the moorings of this buoy were made of sufficient length to
overcome these conditions.

RIO DE JANEIRO.—NATIONAL OBSERVATORY.—RADIO
TIME-SIGNALS.

In the radio time-signals sent out by the National Obser-
vatory of Rio de Janeiro at 11 h. and 21 h. legal time, by
means of the Governador Radio Station (call letters SOH)
will be observed the following conventions :—

At 10 h. 55 m. is made three times the signal of call
(— . — . —) followed by the words “Signaes horarios Rio
de Janeiro,” and directly afterwards, three times, the signal
of attention (. — — . .).

At 10 h. 55 m. 55 s. begins a series of preliminary signals
consisting of the letter O of the Morse alphabet—that is,
consisting of groups of three dashes—these signals, entirely
technical, will terminate at 10 h. 56 m. 50 s. ; they are de-
sign ed for the special use of the observatory, and may, how-
ever, be omitted.

At 10 h. 57 m. will begin the time-signals, which will last
exactly three minutes and will be as follows :—

1. From 10 h. 57 m. 00 s. to 10 h. 57 m. 50 s. signals of
   warning consisting of a series of the letter X (— . . —). Three long dashes, each of a second’s duration, will terminate
   the minute.

2. From 10 h. 58 m. 00 s. to 10 h. 58 m. 50 s. time-signals
   made by dash and point, the points corresponding with the
   exact tens of the seconds. Three long dashes will terminate
   the minute.

3. From 10 h. 59 m. 00 s. to 10 h. 59 m. 50 s. time-signals,
   made by two dashes and one point, the points coinciding
   with the exact tens of the second. Three long dashes ter-
   minate the minute, as with the former.

In case an accident should disturb or prevent the emission
of the signals at 11 h. and 21 h., these will be repeated a half
hour later from 27 m. to 30 m., being joined to the call the
word “Correccao.”

At 20 h. 55 m. will be made the time-signals corresponding
to 21 h., following the same rule.

These signals will be in complete agreement with the rules
of the international convention which met in Paris in the
year 1912.

CHILE.

VALPARAISO RADIO STATION.—WEATHER INFORMATION
SENT DAILY.

From 15th January the Valparaiso Radio Station will
transmit once a day with the same wave-length as that by
which the hour is given, which is 1,100 meters, the meteorologic
conditions of certain points of the coast and of the island
Juan Fernandez.

In order that these signals may be received without diffi-
culty by all vessels they will be transmitted very slowly.

The hour of transmission will be 12 h. 00 m., local mean
time of the meridian 60° W., corresponding with the meteoro-
logical conditions of 10 h. 00 m. of the stations indicated,
hour of the same meridian.

The stations of the coast will be designated in the bulletin
respectively with alphabetical letters, generally the first of its
name, as follows : V, Valparaiso ; T, Talcahuano ; C, Corral ;
J, Juan Fernandez ; M, Mocha ; G, Guafo ; R, Raper.

The signal will be sent, beginning with the letters O. M. C.
(Officina Meteorologica de Chile). Following will be given the
barometric pressure in millimeters, but suppressing the figure
of the hundreds—thus, to indicate a pressure of 753 milli-
imeters the figure 7 will be suppressed and the number trans-
mitted will be 53.

In continuation of this number 53 comes another figure
which indicates the direction of the wind, from 1 to 8, cor-
responding to—1 to north, 2 to north-east, 3 to east, 4 to
south-east, 5 to south, 6 to south-west, 7 to west, 8 to north-
west.

Lastly comes another figure which indicates the force of
the wind according to the Beaufort scale ; but when strengths
greater than 8 are to be indicated they will be given in words,
nine, ten, eleven, and twelve.

In case of it not being possible to communicate the me-
teorologic conditions of any of the stations the word “no ”
will precede the distinctive letter of that station ; and if only
a part of the information is given, for the omitted part will
be substituted the letter X.

If the weather is not good in the ports indicated by the
bulletin there will be added in ordinary language some of
the words : Temporal (gale), neblina (fog or mist), lluvia
(rain), sol (sun).

To assist understanding the foregoing an example of the
bulletin is given, as follows : O.M.C. V5534, T5921, C5172,
M5765, &c., which signifies “ Valparaiso, barometric pressure
755 mm., wind from east, strength 4 ; Talcahuano, baro-
metric pressure 759 mm., wind from north-east, strength 1 ;
Corral, barometric pressure 751 mm., wind from west,
strength 2 ; Mocha, barometric pressure 757 mm., wind from
south-west, strength 5.”
