There is a battery mounting three twenty-four pounders
on the Island of Dalkey, whose highest point is crowned
by a martello tower that differs from any I recollect to
have seen elsewhere. The entrance to the tower is at the
very top of the building, while the doors of most others
stand no more than twelve or fourteen feet from the
ground. Dalkey Island is uninhabited, save by the military stationed in the batteries.
The engraving which accompanies this article also exhibits a view of part of Dalkey common, which extends
from the village of the same name on the west, and the Government quarries on the south side to the sea. There
is a dwelling house of a most extraordinary kind now being
completed on a portion of this common. It is seen in
our drawing, two stories in height, standing alone, with the
front door opening within a few feet of a craggy mountain-
precipice, and its rere (sic) wildly hanging over a dreadful
rocky steep washed by the boisterous sea. The erection
of this extraordinary edifice was a strange vagary of the
projector. The first glance of it at once suggests to the
imagination, ideas of the amphibious retreats of desperate
smugglers, or cruel pirates of bygone times, rather than of
the rural summer haunt of a peaceful citizen. The occupier might repose in it as it is said the celebrated Granuaile used to do in Carrickahooly castle, where her shipping was moored to her bedpost, for the purpose of preventing surprise.
The name of Dalkey common is perpetuated in the
convivial song called the Kilruddery Hunt, written in 1774 by Father Fleming, of Adam and Eve Chapel, and of which
a copy is said to have been presented by the Earl of Meath
to King George the Fourth, when he visited Ireland.
The expression, " Dalkey-stone common," in that song,
leads me to remark that there was formerly a druidical
rocking-stone in the neighbourhood of Bullock or Dalkey.
I find mention made of it by some old writera and also by
Wright, in the Guide to the County of Wicklow : but
although I have devoted several days to searching for it, I
am with regret obliged to say, I have not been able to
find it.
The Government quarries on the common are at present worked by the respectable firm of Henry, Mullins,
and Mc Mahon, who have contracted for the completion
of Kingstown harbour. The largest blocks of granite,
raised in the quarries by the force of gunpowder, are lowered (to the long level of the railway where the horses are
yoked to the trucks) by a succession of three inclined
planes, in the following manner. A large metal wheel
with a groove in it, and revolving freely on an upright
axis, is fixed at the head of each inclined plane. Over
the groove a strong endless chain is passed, and from
thence carried down a railway to the bottom of the inclination, where, running over friction-rollers, it returns up
another rail road, parallel to the former, back to the
wheel first mentioned. When a laden truck has to be
lowered, it is brought to the verge of the descent, and
there attached to the chain. At the same time, an empty
track is fastened at the bottom of the descent to the
ascending portion of the same chain. The laden truck is
then pushed down the sloping rail-road, and by reason of
its weight (from five to seven tons) proceeds rapidly down,
drawing at the same time the empty truck up from the
bottom of the parallel railway. There are generally three
laden and as many unladen carriages moving up or down
the steep in this manner at the same moment. Should
the motion become too rapid, a man at the top has the
power of regulating it by means of a friction-band, which,
with the help of a compound lever, he can close upon the
grooved metal wheel. The same contrivance serves to stop the descent altogether, the instant the trucks have
arrived at their destination. Thus, by the aid of a simple
combination of mechanic powers, a single man is enabled
to move and controul (sic) the motion of six heavy carriages,
bearing an aggregate weight of granite of about twenty
tons, a task which it would require twenty-seven horses,
with the ordinary modes of conveyance on common roads
to accomplish.
The village of Dalkey stands about seven miles from
Dublin, at the northern side of Dalkey hill, on which was formerly a telegraph, now dismantled, and nearly undermined by the quarrymen in the neighbourhood. The village was formerly a place of great importance. During
the reign of Queen Elizabeth, it was a repository for the
goods imported or to be exported by the merchants of
Dublin. The ruins of several castles are still remaining
here; they were built for the protection of trade against
the hordes of land and sea robbers that infested the country at a remote period.
