I lhall conclude this account of Dufky Bay with fome obfervations
made and communicated to me by Mr. Wales.
He found, by a great variety of obfervations, that the latitude
of his obfervatory at Pickerfgill Harbour, was 450 47'
s6".J-South; and, by the mean of feveral diftances of the
moon from the fun, that its longitude was 166° 18' Eaft; which
is about half a degree lefs than it is laid down in my chart
conftrudted in my former voyage. He found the variation
of the needle or compafs, by the mean of three different
needles, to be 130 49' Eaft, and the dip of the South end 70°
5'i-. The times of high water on the full and change days,
he found to be at io11 57', and the tide to rife and fall at the
former eight feet, at the latter five feet eight inches. This
difference in the rife of the tides between the new and .full
moon is a little extraordinary, and was probably occafioned
at this time by fome accidental caufe, fuch as winds, &c.
but, be it as it will, I am well allured there was no error in
the obfervations.
Suppofing the longitude of the obfervatory to be as above,
the error of Mr. Kendal’s watch, in longitude, will be i° 48',
minus, and that of Mr. Arnold’s 39', 25". The former was
found to be gaining 6", 461 a-day on mean time, and the latter
lofing 99", 361. Agreeably to thefe rates the longitude by
them was to be determined, until an opportunity of trying
them again.
I muft obferve, that in finding the longitude by Mr. Kendal’s
watch, we fuppofe it to have gone mean time from the Cape
of Good Hope. Had its Cape rate been allowed, the error
would not have been fo great.

Pajfage from Dujky Bay to Queen Charlottes Sounds with
an Account o f fome W<ater Spouts, and o f our joining
the Adventure.
A FTER leaving Dufky Bay, as hath been already men- M i
tioned, I directed my courfe along fhore for Queen 1----.----1
Charlotte’s Sound, where I expected to find the Adventure. Tu£fdayl1-
In this paflage we met with nothing remarkable or worthy
of notice, till the 17th at four o’clock in the afternoon. Being Monday 17.
then about three leagues to the weftward of Cape Stephens,
having a gentle gale at Weft by South, and clear weather,
the wind at once flattened to a calm, the fky became fud-
denly obfcured by dark denfe clouds, and feemed to forebode
much wind. This occafioned us to clew up all our
fails, and prefently after fix water-fpouts were feen. Four
rofe and fpent themfelves between us and the land; that is
to the S. W. of us; the fifth was without us ; the fixth firft
appeared in the S. W., at the diftanceof two or three miles
at leaf! from us. Its progreflive motion was to the N. E.
not in a ftraight, but in a crooked line, and palled within fifty
yards of our ftern, without our feeling any of its effects..
The diameter of the bafe of this fpout I judged to be about
fifty or fixty feet; that is, the fea within this fpace was
much agitated, and foamed up to a great height. From
this a tube or round body was formed, by which the water,,
or air, or both, was carried in a fpiral ftream up to the
clouds. Some of our people faid they faw a bird in the onenear
