Major-Gen. Sir H. Jones, Royal Engineers, and
the other members of the Defence Commission. at-
tended by Col. Peters, Royal Artillery, and Col.
Wright, Royal Engineers, went on Monday in the
steam tender Vivid, W. H. Allen master, round
Plymouth Sound, for the purpose of examining the
fortifications. They landed at Bovisand Point and
on the Breakwater. The Vivid then swept round
Cawsand Bay, continuing some time under the new
battery at Picklecombe Point, Mount Edgcumbe,
and proceeded towards Hamoaze, until near Eastern
King; Point, where she waited an hour, for the
purpose of surveying the fortifications there. She
then went up the Hamoaie as far as Saltash. The
fort or battery at Bovisand was erected about ten
years since half way up the steep part of Staddon
Heights. After its erection it was discovered that
in case of attack an enemy's balls flying over the
artillerymen would strike against the hill and,
rebounding, cause probably more destruction than
if the fort was hit point blank. With-a view to
remedy this defect a wall has been carried up
behind. The batteries are built of and faced
with granite, which it is feared when struck will
prove very detrimental to the men at the guns.
Some experienced engineers consider that instead
of being on any part of the hill this battery should
have been level with .the sea—a raking shot being
much more effective against shipping than one
dropped from a height. It is understood that the
military authorities have long contemplated the
utility of erecting batteries on the breakwater, and
it is stated that they intend the erection to be in-
side the present structure. It is to be hoped that
the authorities will contemplate the possibility of
erecting the proposed battery outside the break-
water, where the water space is comparatively of
no use, rather than encroach on the anchorage
ground in the Sound, where every square inch is
of so much value.
The screw gun vessel Pioneer, 6, Commander H.
Reilly, was taken out of dock on Monday, and will
probably leave Plymouth soon for her station on
the West Coast of Africa.
