I paid a visit to the port, distant from the town about five miles, made easy by an excellent macadamized road, carried, in some places, on a causeway over a swamp, and forming a great and imperishable monument of the Governor's enterprising spirit. The port reminded me of one of the quiet mangrove creeks on the North coast, except that it had only one bend, changing from a northerly to a south-westerly direction, which at certain times of the day renders it navigable, with a fair wind, each way. For instance, the seabreeze will take a vessel out through the northerly part, and next morning she will have the land breeze to carry her the rest of the distance; whilst, alternating, the same breeze serves to take ships in. The mouth of the port is well marked with black and white buoys; and a light vessel is moored off the entrance, with pilots in attendance; a red buoy is on the bar, where at high-water there is sometimes 15 feet, but the tides are very irregular, being much higher with south-west winds; the general rise was about four feet. MR. EYRE'S EXPEDITION. We were very much pleased with the animated description we had of the departure of Mr. Eyre's expedition to the north; but what gave us particular satisfaction was the evidence afforded of how much the whole colony had the welfare of this enterprising little band at heart. I had not before seen in Australia any place where the progress of discovery was so liberally forwarded, as the readers will at once learn from Mr. Eyre's book. One cause of this we may discover in the fact that the richness of the country immediately surrounding Adelaide made them eager to ascertain its extent. Indeed until this was known they were necessarily unsettled, as few liked to locate themselves permanently until the extent of the field within which they were to make their choice was determined. To what extent the colonists of South Australia are indebted to the sacrifice of property, the loss of time, the bodily fatigue, and unceasing exertions of Mr. Eyre, I also leave the reader to gather from his own lucid narrative. The country has now been found to be almost hemmed in by sterile districts; and the good lands, contrary to our experience of the rest of the continent, to be nearly all in one spot. A number of enterprising colonists, therefore, concentrated within comparatively narrow limits, could not fail of developing the resources of the country, and of discovering what mineral treasures it may contain. The good encouragement it has lately received has, to a certain extent, assisted in bringing it back to the position of one of the most thriving colonies in Australia; though we must attribute much of its present prosperity to the impulse originally given by the policy of Colonel Gawler, which, though it may have caused a temporary financial embarrassment, is now making its happy effects sensibly felt.
