It may be convenient to state here that many instances could 

 be given in the writer's experience of the accuracy that it is 

 possible to obtain by the methods we have so far employed, 

 as manifested by the subsequent close agreement of the beacon 

 triangulation when connected with the shore objects. A 

 replot is not necessary, though some alteration in the provisional 

 bearing may be expected. The soundings dependent upon the 

 sextant angles to the beacons that may have already been in 

 progress are not affected thereby.

CONNECTION OF THE FLOATING TRIANGULATION WITH 



THE SHORE OBJECTS AND DISPOSITION OF THE 



SHIPS ENGAGED. 



See Figs. III. and IV. 



With conspicuous elevated shore objects this may be done 

 during daytime dependent upon the weather. Any disposi- 

 tion of the ships that may be contemplated near the extremes 

 of the triangulation should be so arranged that the ships 

 are intervisible at the greatest distance possible.
