Ta? south-east trade cannot be said to blow home upon Section L that part of the coast of New South Wales, which lies be- East twecu Breaksea Spit and Port Jackson, except during the summer months, when winds from that quarter prevail, and often blow very hard; they are then accompanied by heavy rains, and very thick weather: generally, however, from October to April, they assume the character of a sea-breeze, and, excepting during their suspension by south-easterly or westerly gales, are very regular.
