Before quitting Sydney I must express my gratitude for the hospitality we experienced during our stay, which prepared us with greater cheerfulness to encounter the difficulties we might expect to meet with in the boisterous waters that rolled between the then imperfectly known shores, and islands of Bass Strait. It was not until the 11th of November that we bade adieu to our friends, and sailed to commence our contemplated operations. On the 14th we passed the rocky islands (Kent's Group) at the eastern entrance of the Strait, their barren and bleak appearance bespoke the constant gales that swept over them, checking every tendency to vegetation. As we approached them the soundings decreased to 28 fathoms, the observation of which fact apprises vessels coming from the eastward in thick weather, of their proximity. After leaving these islands we progressed but slowly, and the passage through the Strait promised to be tedious: yet, as the wind was fair and the weather fine, we had no reason to complain, considering moreover the remarkably mild reception we met with in the Funnel, the name commonly and most appropriately given by the colonists to Bass Strait, from the constant strong winds that sweep through it. WILSON'S PROMONTORY. On the 17th we passed Wilson's Promontory, the southern extremity of Australia, connected with the main by a low sandy isthmus, only left dry it is probable of late years. It is a very mountainous tract, rearing its many peaks in solemn grandeur from the waves and burying their summits* at most seasons of the year, in a canopy of grey mist. On some occasions, however, the bold outline of the mountains is relieved against a clear sky, and their loftiest points catch the first rays of the morning sun, as it rises from the eastern ocean. Many small islands are dispersed over the sea in front of this promontory, and partake of its character, being apparently the tops of mountains thrusting themselves up from the deep, and suggesting the belief that new countries are about to be disclosed. Passing Port Western, generally called Western Port, a high mound on the south-eastern extremity of Grant Island was the most conspicuous object. The next remarkable feature in the coast is Cape Shanck, a projection at the western end of a long line of cliffs. Lying close off it is a rock, named, from its exact resemblance, Pulpit Rock.
