both bars; drove the ends of the bars 5*-in. across 
the mouth of embrasure; knocked down the four 
top bars and cracked the masonry. Indent 3‘1-in. 
Hit the bar which formed the top of the mouth of the 
embrasure at its extreme end, just over the wood 
backing, which it crushed in, made a small indent, 
and brought down six more bars. The target was 
now so destroyed that the firing was discontinued, 
and the 120-pr. shunt gun was laid on the old 10-in.
