TÍMARIT V. F. 1. 1922
m and 500 m long respectively, and a landing pier
of abt. 250 m with a bridge-head. The cost is
estimated at about Kr. 11,750,000. In his notes
from 1919 Mr. Kirk points out the necessity of
having large blocks of concrete to protect the
moles. He had measured two stones of 9 and 40
tons respectively which had been hurled by the
heavy sea 25 m and 15 m and lifted 3 m and 1,25
m respectively.
The area of the harbour is about 30 hectars at
low-tide, of which 21 hectars have more than 4
m of water. (A detailed account of the project
appeared in the 1919 issue of this journal, page
33—42.).
17. Eyrarbakki, mapVIII. Eyrarbakki is
an old trading station, and though the fishing is
not of great importance, it would be justified on
account of the export and import to improve the
harbour as much as possible. The entrance is very
narrow and winding on account of a row of sunken
rocks which lie outside the harbour and in them-
selves offer some protection. The entrance could be
improved by blowing up the rocks „Bryggja“ and
„BrúnkoIla“. This would make the entrance to the
inner harbour fairly good. If at the same time a
wall of 500 m, the top 4 m above low-water level,
was built on the row of rocks outside the inner
harbour, which are dry at low water, from „Hrafn-
sker“ to „Landsuðursker“ good protection would be
obtained for motor and rowing boats. The harbour
is too shallow for larger craft.
The cost of these structures is estimated at:
improvement of entrance..............Kr. 475,000
construction of mole.................— 250,000
total Kr. 725,000
18. Stokkseyri, map VIII. The fishing
here is fairly good, but the natural conditions are
very unfavourable, and it would only be possible to
carry out harbour constructions at a prohibitive
cost, and even so the harbour would not be really
safe or protected. The entrance can be improved by
blowing up rocks on the westem side to a depth
of 1,5 m and a width of 1,75 m, which would be
of assistance for smaller craft, and is estimated to
cost abt. Kr. 15,000. A new landing-bridge in con-
tinuation of the „Ingólfs“ bridge would cost abt.
Kr. 25,000.
19. L o f t s t a ð i r. Loftstaðir is not of any im-
portance, and it would not be possible to carry out
any harbour works here.
2 0. Vestmannaeyjar (Westmann Is-
1 a n d s). The harbour constructions at this impor-
tant fishing place as shown on map XX are now
being carried out under the direction of civil-
engineer, Councillor of State, Mr. N. C. Monberg.
II. The South Coast.
The south coast is the most difficult part of Ice-
land as far as harbour conditions are concerned, and
the results of Mr. Kirk’s examinations were on the
whole negative, which is in accordance with previous
statements on the same subject. The following
places were visited:
21. Dyrhólaey. The landing conditions are
very difficult here, as the sandy coast lies quite
open to the Atlantic Ocean. Moreover the soundings
which were taken round the Portland rock show
that the depth just outside these rocks — the only
place where it would be possible to build some pro-
tection for the landing — is so great that this in
connection with the solid construction of a pro-
tecting mole which is required on account of the
heavy seas would make the cost of even the smallest
stmctures here quite unreasonably high.
2 2. Vík in Mýrdal, map IX. This is a
small trading station with an open and sandy coast
with no other cover than that obtained from the
rock of „Reynisfjall“ on the western side. The na-
tural conditions are bad, and as the depth of the
water seems to be variable it would be out of the
question to undertake any construction here before
careful soundings have been taken over a number
of years. The depth was measured in 1919, and it is
intended to repeat the operation with an interval of
2—3 years.
It might be possible to impi'ove the landing con-
ditions by building a road from the town to „Bás“,
which is a small cut into the side of „Reynisfjall“
where boats sometimes land.
In Bás a mechanical contrivance would have to
be erected to hoist the goods on to the platform
from where the road should commence, and, as
shown on map IX, a small mole could be built across
the rocks in the sea to protect the landing. Such
a mole, 165 m long, would cost abt. Kr. 500,000, and
the road-building and hoisting apparatus would
come to abt. Kr. 15,000.
It must, however, be taken into consideration that
these rocks are of a very loose substance, and are
continually crumbling and falling down in parts.
Bás itself has been formed in this way, and another
slide of the rocks might easily fill the place, and
make it useless, besides destroying the hoisting
apparatus and causing other damage.
2 3. Ingólfshöfði. The conditions are similar
to those in Vík, and it is out of the question to
make any harbour constructions here.
