COAST DEFENCE AGAINST TORPEDO-BOAT ATTACK . 
Ignorance as ^ ev ^ ent khat knowledge of siting electric

given facilities for taking up the question, it is not 
likely to grow fast. The Navy, who have constant practice, have 
learnt to site their lights as high as they can be conveniently worked. 
There are few fortresses in which they cannot be placed higher than 
on board ship.

the power of the guns relieving the wandering beams of the custody 
of any boat that they found and permitting it to search for others. 
It is somewhat doubtful if fighting lights would confer much advan¬ 
tage if no high ground is available for either guns or lights, for they 
would then be liable to blind some of the guns, but repeated trial 
during manoeuvres would discover some sites where they could be used 
with advantage to the defence. 
Yery often parachute fire-balls, or something of that 
nature, would be extremely useful to give a general 
view over water areas, but here again a difficulty for Garrison 
Artillery crops up. Laboratories are no longer at their command and 
unfortunately c fire-working ’ is no longer a part of their training, so 
that the adaptation of artillery materiel to fighting requirements as 
they arise is practically impossible. The genius of modern Garrison 
Artillery finds its grave in requisitions on departments. Even the 
well tried and clever inventions of past artillerymen are being lost to 
modern use ; they are unattainable if not in some store schedule.
