Another portion of the wood sinks, before it reaches the sea,
often in such a way that the stems stand upright in the river
bottom, with one end, so to say, rooted in the sand. They may
thus be inconvenient for the navigation, at least at the shallower
places of the river. A bay immediately off Port Dickson
was almost barred by a natural palisade-work of driftwood
stems.

_August 7th._ The _Vega_ coaled from the _Express_. In the evening
the _Lena_ arrived, 36 hours after the _Vega_ had anchored, that is
to say, precisely at the appointed time. Concerning this excursion.
Dr. Almquist reports:

"On the 2nd August we--Horgaard, Nordquist and I--went on
board the _Lena_ to make an excursion to Beli Ostrov. We
were to land on the south-western headland and there
undertake botanical and zoological researches. Thereafter
we were to direct some attention to the opposite shore of
Yalmal and visit the Samoyeds living there.

"We left the _Vega_ at eleven o'clock forenoon. In the
course of the day we saw here and there in the south
scattered ice, and at half-past ten at night we ran into a
large belt, about 300 metres broad, of scattered ice,
which lay stretched out from N.E. to S.W. It was passed
without difficulty. In the course of the night we now and
then fell in with a little scattered ice, and in the
morning with a belt of masses of ice of considerable
dimensions; sounding constantly in 10 to 3-1/2 metres
water we succeeded, notwithstanding the fog and rain, in
finding the straits between Beli Ostrov and the mainland,
and on the 3rd August at eleven o'clock forenoon we
anchored a little to the east of the southern extremity of
the island. The _Lena_ lay in 3-1/2 metres water, about an
English mile out to sea. The water was shallow for so
great a distance from the beach that we had to leave our
boat about 300 metres out to sea and wade to land.

"Beli Ostrov consists entirely of fine sand, and only on
that part of the beach which is washed by the sea-water
did we see any stones as large as walnuts; higher up we
did not find a piece of stone even of the size of the
nail. The highest point of the island appears to be
scarcely three metres above the surface of the sea. That
part of the island over which the sea water
