teen white stars flies in the bows of the boat

 stroyer flotilla is a swallow-tail pennant of 

 plain white bordered above and below with

 of peace a submarine warning flag is flown on

 the same design.

84. The battle efficiency pennant is one of 

 the most coveted trophies of the American 

 navy. There is one for each class of ships, 

 such as battleships, destroyers, and submarines. 

 The ship of a given class which, during the 

 preceding year, has shown by her practice and 

 performance the ability to hit most often and 

 quickest, to steam the farthest with the least 

 expenditure of fuel, water, etc., to run longest 

 without breakdown, and which otherwise gives 

 evidence that she might be expected to give a 

 better account of herself in a battle than any 

 other vessel of her class, is awarded the privi- 

 lege of flying- the battle efficiency pennant dur- 

 ing the ensuing year. There is the keenest 

 rivalry between the competing vessels of a 

 class, and this little red triangular flag with 

 the black disk is prized next to victory in bat- 

 tle itself. 



85. This flag is flown by vessels engaged in 

 convoy duty. When ships are engaged in ma- 

 neuvers or are maneuvering in compound for- 

 mation, this pennant is an indication to the 

 other vessels of the division to take bearing 

 and distance from the ship bearing it. 



86. Hospital ships fly the Red Cross flag, and 

 under international law they are immune from 

 attack, unless it can be shown that the ship 

 flying it fails to respect all of the provisions 

 of the international compact made at Geneva. 



87. This is the flag under which the marine 

 corps moves quartermaster's supplies for its 

 men. 



88. The interrogatory flag is used in signal- 

 ing when one ship wants to make a signal in 

 the interrogatory form or to announce that it 

 does not understand a signal. 



89. The preparatory flag is displayed with 

 a signal in order that preparations may be 

 made to execute the signal itself uniformly and 

 simultaneously. When the signal alone is 

 hauled down, the ships having made ready, 

 execute the signal. It is also hoisted when 

 the ceremony of hoisting the colors in the 

 morning and taking it in at sunset is the next 

 thing on the program. It is raised five min- 

 utes before the ceremony begins. Upon being 

 hauled down by the flagship, all ships execute 

 the colors ceremony simultaneously. 



90. This flag is displayed either to counter- 

 mand the last signal made or the one then be- 

 ing shown. 



91. This pennant has two uses. Its first use 

 is in answering a call for a semaphore or wig- 

 wag message, being hoisted half way when the 

 ship is ready to receive the message, and all 

 the way when the message has been completely- 

 received. It is then hauled down. Used thus, 

 it might be said to be the "Aye, aye, sir" flag 

 of the navy. Its other use is as a decimal or 

 divisional flag in flags indicating numerals and 

 quantities. 



92. This is the "No" flag of the navy. It 

 is used to negative a request, or to say "No" 

 to a question. 



93. The brigade pennant of the United 

 States Alarine Corps has a swallow-tailed blue 

 field, with the number of the brigade and the 

 initials of the corps in gold. 



94. When a ship asks permission of the 

 flagship to do this or that, the force com- 

 mander hoists this flag with the number dis- 

 tinguishing the vessel making the request, as a 

 sign that it has been granted. 



95. The yellow flag, as is well known, is 

 the one which proclaims that there is conta- 

 gious disease aboard. 



96. This flag has two uses. Hoisted at the 

 main mast, it means that the vessel displaying 

 it is engaged on dispatch duty. It is always 

 carried in a roll at the fore mast of vessels in 

 formation, so that it can be displayed, or 

 "broken out," as the sailors say, instantly, to 

 indicate an accident or derangement on board 

 that vessel and to warn other ships to keep 

 clear. Hoisted half way, clear of the smoke- 

 stack, it indicates a man overboard. 



97. The church pennant is always displayed 

 when divine services on board are in progress. 



98. The cornet flag, displayed at the yard 

 arm. calls all vessels present to receive a sema- 

 phore or wig-wag message. Displayed at the 

 fore mast, it is notice to all officers and men 

 to come on board at once. 



99. The guidon of the United States Marine 

 Corps has a blue field, is gold fringed, and 

 bears in gold on the field the initials of the 

 corps. 



100. This flag, displayed with 101, 102, 103, 

 104, 105. 106. 107, 108, no, and in. indicates 

 that they represent in value the numerals given 

 below them. If those flags are not displayed
