should be obtained under any circumstances, with our present service 
ammunition. It is satisfactory to contemplate the possibility, under 
any circumstances, of striking a column of infantry in anything like 
1194 places at nearly a mile range, in firing fifteen rounds. 
Looking at the exact character of the action, it may be noticed that 
every single effective shell bursts within five yards of a target, and 
nearly all burst through one of the targets on to those behind it. Judging 
from many results, this is the most effective action of the segment shell, 
but of course it can only be employed on columns.

with time and percussion fuzes—and these are not fuzes made in the 
Laboratory, but the genuine article, fresh from Elswick. In this, 
although ten shells burst and one breaks up within 60 yds. of the front 
of the targets, the effect is comparatively small, being very nearly the 
same effect as is produced on the front target by nine shrapnel bursting 
* A better result was obtained with segment shells fired with time and percussion fuzes on 
another day, but it happened that the chief effect was due to four shells bursting by percussion fuzes 
through the second row on to the third and fourth rows {vide Pig. 3), the first two rows having

tiit few scores on thein; and this being so, the result bears out rather than contradicts the 
principle laid down—viz. that the action of the segment shell requires a percussion fuze to develope 
it to advantage.
