this drifter, inward-bound traffic may proceed to pass through
the gateway.
To indicate that the gateway is clear for outward-bound
vessels, the drifter will display by day a black shape and by
night two horizontal white lights.
During fog three long blasts on the steam whistle, repeated
at intervals of five minutes, will indicate that the gateway is
clear for outward-bound traffic.
Vessels making Mounts Bay in foggy weather should be
careful to sound the regulation fog-signal and to proceed
with great caution when within a depth of 25 fathoms at all
states of the tide.
When the gateway is clear for inward-bound traffic, no
outward-bound vessel may approach within half a mile of
the gateway; and when the signals indicate that outward-
bound traffic may pass through the gateway, no inward-
bound vessel may approach within half a mile of the gateway.
During the hours of darkness, all vessels entering or leaving
Penzance Bay must exhibit their side-lights.
Before attempting to leave Penzance Bay, outward-bound
vessels must obtain instructions as to the route to be followed.

PANAMA CANAL.

CAPTAINS OF THE PORTS.

1. The Captains of the Ports, under the Marine Superin-
   tendent, are charged with the general supervision and enforce-
   ment of the rules and regulations relating to the navigation
   of the Canal, terminal ports, and waters adjacent thereto,
   and with the enforcement of harbour regulations. They are
   charged with the berthing and mooring of vessels, inspection
   and admeasurement of vessels, supervision of pilots, despatch
   and transit of vessels through the Canal, and they shall
   generally regulate the movement and berthing of all shipping
   and floating equipment in so far as it relates to the safe and
   expeditious navigation of vessels through the channels and
   terminal ports of the Canal. In all cases of regulation of
   the movement of shipping and floating equipment pertaining
   to the Panama Canal or Panama Railroad Company, the con-
   venience and requirement of the work on which it is engaged
   will have full consideration, and will not be interfered with
   except for reasons affecting the safety of the navigation of
   the Canal, for which the Marine Superintendent is responsible
   to the Governor.
2. The Captains of the Ports shall use every facility under
   their control to expedite shipping and to assist the various
   departments and divisions in rendering service to shipping,
   and shall, as far as possible, so co-ordinate the work of the
   Canal as a servant of commerce that steamship masters,
   agents, and representatives of shipping may make their needs
   known to the Captains of the Ports, and may feel that, as
   far as practicable, they may deal with a single office rather
   than with a number of separate heads of departments.
3. When a request for services or work in connection with
   shipping or shipping interests is received from a Captain of
   the Port by a responsible official of any department or divi-
   sion, or branch of either, it will be considered as sufficient
   authority to provide the services or to proceed with the work.
4. The Captains of the Ports are charged with the entrance
   and clearance of all vessels that enter and clear the terminal
   ports of the Canal Zone, and will deny the entrance or de-
   parture of vessels until all laws and regulations concerning
   quarantine, Customs, immigration, and navigation are com-
   plied with, and until all tolls and other dues are paid. They
   shall be supplied with all necessary information and documents
   by the various departments and divisions of the Panama Canal
   and Panama Railroad Company, in order that these entrances
   and clearances may be accomplished expeditiously.
5. The Captains of the Ports shall prepare and keep cor-
   rected to date all information in regard to vessels entering
   Canal Zone waters, including names, nationalities, line or
   company, measurements, tonnage, character of cargo, time
   of arrival and departure, port of departure and destination,
   and all other information in relation thereto which may be
   of interest.
6. The Captains of the Ports shall be prepared, as far as
   possible, to keep all other departments informed on matters
   of interest to them in relation to shipping, and to furnish
   shipping with full information in relation to Canal affairs.
7. The Captains of the Ports shall furnish tugs for towage
   through the Canal, handling vessels, and shifting berths, as
   may be necessary, and shall be prepared to furnish tugs,
   barges, lighters, and other floating equipment for the use of
   vessels in the terminal ports, or for other departments, in any
   part of the Canal Zone waters.
8. The Captains of the Ports shall each keep on hand,
   corrected to date, a set of charts, a light list, sailing directions,
   and such other data as are usually kept in the United States
   branch hydrographic offices, and shall be prepared to give
   information to masters and others in relation to the navigation
   of Canal waters and the usual steamship routes. They shall
   keep standard time of the 75th meridian, corrected to date,
   and shall furnish chronometer comparisons when requested.
9. The Captains of the Ports shall assist in protection
   against fire in the harbours and on the wharves and all
   buildings along the waterfronts.
10. Through the pilots, tug-masters, and others, the Cap-
    tains of the Ports shall carefully note all accidents, collisions,
    or damages to vessels, floating equipment, wharves, aids to
    navigation, &c., which may be the cause of complaint or
    result in liability for damages, and shall be prepared to give
    evidence or recommend adjustment, as the case may warrant.
11. Vessels in Canal Zone waters should address all in-
    quiries regarding these rules, tolls, other charges, supplies,
    and similar matters to the Captain of the nearest port.
