From off the Cape to St. Helena on the 11th August

Mauritius to the Cape (see above) . 22 days.
From Mauritius to St. Helena in 4 weeks 6 days,or 34 days.
This is an excellent passage. I t appears to be a great
object in making a passage from India to England, to pass
the Cape without going in ; for it is often easy to round the
Cape and go to St. Helena, when it is difficult and tedious
either to go to Simon’s or Table Bay, and much delay is
produced by the difficulty of getting out of the former anchorage.
16.
From St. Helena to Ban try Bay in Ireland.
Sailed from St. Helena on the 14th August, 1817.
Arrived off Bantry Bay, 14th October, 1817 61 days.
This passage was unusually long, owing to a succession
of hard gales from north-east to south-east, which we encountered
in latitude 47° north, longitude 13° west, beginning
on the 27th of September, and continuing, with
little intermission, till the 8th of October; after which period
the weather became fine, but the wind hung constantly to
the eastward, so as to render it difficult to fetch Ireland.
