N.B .—These would be the corrections for the high flank section, half such would be given for the centre 
section. 
This table of corrections is only roughly calculated from the range 
table given on p. 34 of the hand-book for the 15-pr. B.L. gun, 1896 ; 
but, in conclusion, it may be useful to compare the result of using it 
with the practice at 1500 yards described above where no corrections 
were supposed to be given and which proved so ineffective and in¬ 
accurate.

| These would satisfy C. O. 
and he would have every prospect of making good practice. 
The prospect would be still better, if each gun had its own correc¬ 
tion. The six shots would then give the following ranges:— 1500 
yards; 1598 yards; 1547 yards; 1545 yards; 1543 yards; and 1512 yards, 
with the result, that the range would be found within four yards. 
Say all this is not practical. Perhaps not; but, if the difficulty is 
not met, I fail to see how we are ever to rely on laying with clinometer 
from covered positions as a useful method. I wonder if those who 
advocate it have fully considered this difficulty.
