(b) Moveable object , single observation .—When the two named stations 
have telegraphed “Found ” the telegraph operator at the directing fort will 
dictate the moment of observation by calling to the observer “ Noiv” at 
the same time pressing on his telegraph apparatus. 
The operator of the other station thus warned, either by the tinkling of 
his apparatus, or by the mark made upon the morse fillet, will also call to his 
observer “Now . 33 
Finally, having taken the angles and telegraphed them, the signal “ Lone 33 
will be given as before. 
(c) Moveable object , successive observations. —These observations are to 
be made at intervals of one minute, and the process of making each observa¬ 
tion will be the same as that laid down in ( b ). 
The directing fort is to give the signal “ Well 33 after each observation, and 
operations are to be brought to a close as before by the signal “ Lone , 33 
which will in ordinary cases be made after the completion of five observations. 
8. All telegraphic communications exchanged during the measurement 
of distances will be made in general by the wires 1 and 2, the whole line being 
in the circuit. 
9. Keeping the journal.—Every fort is to record in its journal everything 
relative to the measurement of distances. 
Eor fixed objects, the recorded moment of observation is to be that at 
which the first angle is telegraphed. If the object be moveable, the signal 
“ Now 33 gives the moment of observation. 
In cases of successive observation, it will be sufficient to record the 
moments of the first and last observations, with their corresponding distances. 
10. Each station should have all measured distances plotted upon their 
chart. 
11. Examples of measurements of the distances of various objects.
