276 SOCIETY NAVAL ARCHITECTS AND MARINE ENGINEERS. 



The Conference makes the following recommendations : 



As Regards Safety of Navigation: 



The Government of the United States and the Directors of the Suez Canal Company 

 should be asked to publish at Colon, at Panama, and at Suez notices giving every four hours 

 the barometric pressure with the necessary corrections for temperature and the height above 



the level of the sea. 



2. 



The attention of the Governments which have adopted the regulations for preventing col- 

 lisions at sea should be drawn to the necessity of revising these rules and in particular as 

 regards — 



1. Lights on sailing vessels; 



2. Signals to indicate the course of a ship in fog; 



3. Regulations relating to war vessels navigating without lights ; 



4. Navigation in the vicinity of war vessels; 



5. Regulations relating to submarines; 



6. The adaptation of lights and sound signals to the dimensions and speed of modem 



vessels. 



3. 



The Administrations concerned should continue to take steps to insure that the power of 

 lights and sound signals employed on board vessels shall comply fully with the requirements 

 of the international regulations for preventing collisions at sea. 



4. 



In view of the diversity of practice and of the opinion in the different countries, the 

 question of the adoption of a uniform system of helm orders should be considered at the same 

 time as the revision of the regulations for preventing collisions at sea. 



In districts where fog is frequent every lightship on an important outside station should 

 be furnished with a submarine bell. 



6. 



Every large vessel defined by Article 2 of this Convention should be furnished with 

 searchlights for use in rescue work and other urgent cases. 



7. 

 Binoculars should not be provided for lookout men. 



8. 



The tests in use for visual acuity and color perception for officers and lookout men 



should be made sreneral. 



9. 



The question of rendering harbor and tide signals uniform should be considered by the 

 different Governments.
