June 28

June 28.—This morning we passed through a country of an inferior description, making a short stage to a watercourse, named by me the “Crystal Brook;” it was a pretty stream emanating from the hills to the north–east, and marked in its whole course through the plains to the northward and westward by lines of gum–trees. The pure bright water ran over a bed of clear pebbles, with a stream nine feet wide, rippling and murmuring like the rivulets of England—a circumstance so unusual in the character of Australian watercourses, that it interested and pleased the whole party far more than a larger river would have done; this characteristic did not, however, long continue, for like all the streams we had lately crossed, the water ceased to flow a short distance beyond our crossing place.

The country below us, like that through which the Rocky river took its course, was open and of an inferior description, but I have no doubt that by tracing the stream upwards, towards its source among the ranges, a good and well watered country would be found; I ascertained the latitude by a meridian altitude at Crystal brook to be 33 degrees 18 minutes 7 seconds S.

The hills on the opposite side of Spencer’s Gulf were now plainly visible, and one which appeared to be inland, I took to be the middle Back mountain of Flinders; between our camp and the eastern shores of the gulf, the land was generally low, with a good deal of scrub upon it, and nearer the shores appeared to be swampy, and subject to inundation by the tides.
