At eleven o'clock they passed within a mile of a high grassy cape, which is the seaward extremity of a ridge, that, rising up by a gentle ascent, retreats and joins some chains of lofty mountains. A small rocky island lay two miles from it to the WSW. At noon the latitude was 40 degrees 55 minutes 25 seconds, and the longitude 147 degrees 16 minutes 30 seconds.
Early in the afternoon a gap in the land situated at the back of a deep narrow bight, which had for some time attracted attention, began to assume the appearance of an inlet, which they bore away to examine; and, after running three miles, they found they had shut in the line of the coast on each side, and were impelled forward by a strong inset of tide. Continuing their course for the gap, some back points within the entrance soon became distinguishable, and the rapidity of the flood tide was observed to increase with the increasing contiguity of the shores. When the sloop was on the point of entering the harbour, which appeared to be fairly open before her, the water shoaled suddenly, and she struck the ground and lay fast; but fortunately the strong flood in a few minutes dragged her over into deep water, and shot her into the entrance with uncommon velocity.
Having advanced within the entrance, the harbour began to expand itself in a kind of large basin. Its shores were broken into points and projections, between some of which the great strength of the flood tide led them to expect it would branch off into arms. The land lying immediately upon its borders was low, but not flat; well wooded; and those points near which the sloop passed were clothed with a very unusual degree of verdure. The sun being down, the vessel was anchored for the night, and the next day they proceeded with their researches.
They were employed during sixteen days in the examination of this place; and the result of the observations which were made by Mr. Bass in different parts of it, and the neighbouring country, are thrown by that gentleman into one general account.
This harbour, or inlet, which was named by the governor Port Dalrymple, in compliment to Alexander Dalrymple, esq takes its course from the SE between two chains of rounded mountains, stretching inland from the sea with an almost imperceptible increase of elevation; and, after gradually approximating each other, seemed to unite, at the distance of between thirty and forty miles, in a body of rugged mountains more lofty than themselves. These two chains in their relative positions formed an acute angle, being at their greatest distance asunder, as measured along the sea coast, only sixteen miles.
Being limited in point of time (twelve weeks having been deemed by the governor sufficient for the execution of this service), the apprehension of losing a wind favourable for the prosecution of the principal object of the voyage, that of sailing through the strait, deterred them from attempting to reach the head of the river; but it was hardly to be doubted, that its principal source proceeded from some part near the point of union of the two chains of mountains. Allowing this supposition, a great part of its stream must be perfectly fresh; for at the place where they ended their examination, which was not more than half the whole supposed distance or length of the river, it had become half fresh half salt, although its breadth was from half a mile to a mile and a half, and its depth eight or nine fathoms.
The country which Mr. Bass had an opportunity of observing, was a certain portion of that lying within the angle formed by the two chains of mountains, and more especially of the parts which lay contiguous to the water, rather than of those situated in the vicinity of the chains.
The quality of the ground, taking it in the aggregate, was much superior to that of the borders of any of the salt water inlets of New South Wales, Western Port excepted (seen by Mr Bass on his first excursion in the whale boat). The vegetable mould was, however, found to be of no great depth, and was sometimes, perhaps advantageously, mixed with small quantities of sand.
The best of the soil was found upon the sides of sloping hills, and in the broad valleys between them. Some parts that were low and level had a wet and peat-like surface, bounded by small tracts of flowering shrubs and odoriferous plants, that perfumed the air with the fragrance of their oils.* These retained in general the appearance of those in New South Wales, while they were in reality very different. The rich and vivid colouring of the more northern flowers, and that soft and exquisite gradation of their tints, for which they are so singularly distinguished hold with those here, but in a less eminent degree. The two countries present a perfect similarity in this, that the more barren spots are the most gaily adorned. The curious florist, and scientific botanist, would find ample subject of exultation in their different researches in Port Dalrymple.
[* In this particular they differ from the flowering shrubs of New South Wales; none or very few of which were ever found, beautiful as they were in other respects, to possess the smallest particle of odour.]
