THE VALUE OF A HIGH SITE FOR COAST ARTILLERY. 
227 
In addition the high site possesses the three following most im¬ 
portant advantages. 
(1) More extended view; greater facilities for observation of the 
objective and observation of fire. 
(2) Less liability for deck hits to glance. 
(3) Greater immunity from hostile fire. 
VII. The Case of Q.F. Guns. 
All considerations combine to make it imperative to place Q.F. 
guns on a high site whenever it is possible.

We have seen that other things being equal the gun with the 
flatter trajectory is more benefited by the higher site. Q.F. guns as we 
know them to-day, have very flat trajectories, and future improvements 
will tend to make them flatter. 
We have seen that when a range is unknown, an error in estima¬ 
tion is minimised by tangent elevation and a high site: the natural 
objective of the Q.F. gun, the torpedo boat, moves so quickly, and may 
appear so suddenly, that no method is known by which its quickly 
changing range can be measured and communicated. 
We have seen that the more an objective approaches to a horizontal 
target, the greater is the advantage of the high site. The torpedo boat 
presents but a narrow ribbon of freeboard, that may often be almost 
buried in the trough of the waves. 
We are told that shots that strike a deck at less than ]0°, are 
almost sure to glance ; the values of co and S in Table VII. show how 
site affects the trajectory of the Q.F. guns. 
In the confusion of a night attack Q.F. guns on either side of a 
narrow channel might fire into each other, if means were not provided
