CHAPTER IX. 
The Examination oe Range Reports. 
In the preparation of a range report the very greatest care should 
be taken that the fullest and most accurate information is recorded, 
and too much attention to accuracy of observation cannot be paid by 
the range party. For it is by a careful study of the range report 
that we get a vast amount of information regarding the laying and 
setting of fuzes of the battery and are able to deduce the mean errors 
of our guns and the average variation in the ranging of the projectiles 
and the burning of the fuzes. 
Let us take the most important point first, viz., tbe checking of the 
laying of the battery by the results actually obtained and recorded by 
the range party. 
The annexed example is taken from a battery practice report of 
1890, and is an excellent example of the value of this kind of analysis.
