At Swan River, on the 24th of May, 1838, the wind was strong and squally
from North-East by North; sympiesometer standing at 30.74. During the day
the oil commenced to fall, and continued falling slowly until the 30th,
when it was 30.16; during the greater part of this interval, the winds
were light, generally from some eastern point in the morning, and going
round the compass, by north and west, during the day; the nights were
mostly calm, a heavy bank of clouds was collecting between
North-North-East and South-West and the whole western horizon had a
gloomy appearance. On the evening of the 30th, the water had risen
considerably at the anchorage, and the stream ran to the southward; a
fresh breeze also set in from North-East and gradually veered to the
northward, as it increased in strength. On the 31st it blew hard all day,
between North-North-East and North-North-West, with dark squally weather,
much lightning in South-West and heavy rain, that continued all night. On
June the 1st, the gale was at its height, and at 8 A.M. (the
sympiesometer having fallen to 29.93) was blowing a hard gale, with heavy
squalls and rain, from North-West; towards noon the wind veered to west,
but still blew very hard; the sympiesometer now began to rise, and in the
evening the wind was West-South-West and had moderated considerably, the
weather was also clearer, although heavy clouds still hung on the western
horizon.

The next morning (the 2nd) the sympiesometer had risen to 30.26; but this
was much too sudden a rise (0.33 in 24 hours) to allow us to suppose,
that the favourable change in the weather was to be of long continuance;
during the day the oil began to fall again, and the wind veered to West
and North-West and on the 3rd blew harder than ever, with heavy rain,
thunder, and lightning; and, with the exception of occasional intervals,
when the wind moderated, this weather continued until the 10th. The wind
during this time was variable, between North-North-West and
West-South-West, the sympiesometer between 29.81 and 30.16--falling with
the North-West winds, and rising as the wind veered to west and
West-South-West.

This gale, which may be said to have been of ten days' continuance,
caused a very heavy sea upon the coast; the oldest residents at Swan
River said they had never experienced so heavy a sea before. On the 10th
