KERGUELEN’S VOYAGE TO THE NORTH. 781
Pomona to larboard, care muft be taken to keep in with Roufa; and when an ifland is
perceived, called by the natives Inhalla, you muft {teer to come up to it on the fouth,
and leave it to ftarboard, on account of there being no paflage north of the ifland: it
requires a good deal of wind to {tem the current in this paflage. You may alfo reach
Wire-found coming from the eaft by the paflage of Sanda-found. ‘This. paflage is
between the iflands of Sanda and Stronfa, leaving Sanda and Eda to ftarboard, and
Strenfa and Schapinfha to larboard.
After defcribing the paffages and anchoring-places which are in the interior of the
Orcades, I fhall make mention of what concerns the exterior, which is not lefs impor-
tant to veflels which may be driven upon the coafts. I fhall begin by the fouthern part,
or ftrait of Pentland, which is, as I believe I mentioned, between Scotland and the Or-
cades. On coming from the eaft to make this paflage, an ifland, which is at the en-
trance, mu{t be kept at a mile’s diftance; it is the fame thing whether a-head of it
north or fouth. After pafling this ifland it is requifite to {teer through mid-channel, and
rather keep clofe to the Orcades than the Scotch coaft, on account of many rocks under
water on the Scotch fide ; but after reaching the fouth fide of the ifle of Hoy, an ifland
in the middle of the ftrait is to be kept at W. quarter S.W. When at no greater
diftance than a league and a half from this ifland, nothing remains to be apprehended
from the Scotch fide: itis the fame whether this ifland be pafled on the north or fouth
fide, there being twenty-five fathoms water on both fides. When this ifland, called
Stroma, is pafled by, the channel opens, and the currents are lefs forcible. Stroma muft
not be coa{ted too near, as it is furrounded with rocks. N.N.E. of Stroma, in the ifle
of Hoy, there is a creek with anchorage in four fathoms water. On the eaft fide of the
Orcades the fhores are tolerably fafe ; almoft every where there is thirty fathoms water
at half a league from the fhore. On lufling near her fhores, one may prolong a tack
without apprehenfion when the wind is ftrong; but when there is a chance of acalm a
greater diftance mutt be kept, for fear of being carried away by the currents. On the
eaftern fide of the Orcades, the point of Sanda is the only dangerous one ;_ neverthelefs
the rocks from this point advance no more than half a league to fea towards the N. E..
North of this point there is a {mall ifland, which is only fafe on the fouth fide ; there a
veffel may anchor to take fhelter from a north wind. This ifland is called North Ro-
naldfa. North of the ifle of Sanda there are two rocks under water near to fhore; but
two leagues from the north point, and N. quarter N. W. of it there is a dangerous rock.
above low water.
Any veffel may anchor north of the ifle of Edda, fouth of a fmall and perfeétly fafe
ifland, called Kale of Edda. At the north point of Weltra there are rocks a quarter of
a league from fhore ; but the fouth part of this point affords a creek, open to the eaft,
where a frigate may anchor under fhelter from the W. or N.W. A league N. E. of
this anchorage is the ifland of Papa Weftra, furrounded by rocks on the weft, north, and
eaft: they extend more than a quarter of a league on the eaftern fide. The weltern:
fhores of the Orcades are for the moft. part very fafe: they may be coafted as-clofe as
you pleafe; but care muft be taken of the currents which run through the ftraits. I
obferved in 1768 on thefe coafts 20° 40! of variation in the needle. I mutt not forget
to notice that there are rocks, about ten leagues weft of the Orcades, about lat. 59°
2’ or 3/: there is one above water; they are called the Stacks. A league north of
thefe are others, three fathoms under water. It is high water at the Orcades. at full
and new moon at forty-five minutes pa{t two.
Between the Orcades and Shetland there is a fmall ifland, called Fair-ifle. As this
ifland is in the middle of a much frequented paflage, called the Tun, I paid particular at-
tention
