MINUTES OF PROCEEDINGS OF 
No. 5 places angle finder on I/’s, works short telescope and sees that 
No. 2 reads the tens correctly; replaces finder when the No. 5 at the 
outer gun no longer wants it. 
Outer Gun . 
No. 1 keeps his gun well to the rear , so that it may, on the word 
“ Forward,” come up to the right position without reversing. 
Posts himself square with the wheels of the pivot gun. 
At the word “Forward” the gun is brought up between him and the 
pivot gun, the wheels being thus square with those of the pivot gun. 
No. 1 does not aid in unlimbering, he lays his gun, hut immediately 
cedes his place to the No. 1 of the pivot gun. 
He then sees that the roller is correctly worked, and that the Nos. 
5 check the readings (from the tens) of the Nos. 3. 
3 uses roller. 
2, 4, 5, as at pivot gun. 
To find the range of a moving object. 
A moving object is one that can move, whether at the moment sta¬ 
tionary or not; it includes men, horses/guns and wagons. 
In finding the range of troops, right and left will mean our own right 
and left, and will he irrespective of the front of the enemy. 
In this case No. 1 of the pivot gun does not quit his gun. Both Nos. 
1 lay their guns on the designated object, following it with the traversing 
screws. As the chief point is to he quite certain that both guns are 
trained on the same object, either of tbje Nos. 1 will describe to the 
other anything peculiar in the man or gun layed on, as— 
“ The horse has two white stockings and is switching its tail; the man 
is an officer and has a paper in his hand.” Or— 
“ The gun has just fired, the men are running it up, and the man on 
the left has his arm stretched out.” 
Both Nos. 1 follow the moving object, calling “on” every two seconds; 
when both together call “on,” the officer calls “Halt,” the operation is 
then concluded as with a stationary object. 
The distance found is that of the object at the moment halt is called. 
If the guns are inverted at drill, and the right instrument is found to 
be on the left, and the left on the right, then the word “ change finders ” 
should be given, and the Nos. 5 should change the instruments. 
Care of the Instrument. 
The screws of the case, or of the tangent screw handle, may always be 
loosened or tightened without affecting the setting of the instrument. 
After a day’s work the twist should be taken out of the tape. 
The hasp securing the lid of the box should be turned during travelling 
or firing. 
If a drop of rain gets on the eye-piece, the cap can be screwed off and 
the moisture removed. 
Description of the various Parts of the Range-Finder. 
This description being given solely with a view to effect any repairs 
that may become necessary in the range-finder, the reader is supposed 
to have in his possession a set of the instruments.
