HYDROGRAPHICAL SURVEYING [chap. xxi. 



SECTION VIII. 

 SIGNALLING ANGLES BETWEEN SHIPS ENGAGED. 



When signalling a series of angles between ships, some simple 

 method must be adopted that i.s not liable to confuse signal- 

 men, and that will reduce the risk of mistakes. 



It should be an invariable rule that all figures, bearings, and 

 the essential data, should be repeated from the receiving ship 

 until they are known to have been correctly received. 



It is necessary to distinguish the beacons by prearranged one- 

 syllable names. 



A signal would read in order thus (the bearings being always 

 magnetic unless otherwise stated, and the time quoted being 

 that in use aboard all the ships, such as G.M.T. or local mean 

 time) :
