The little creek, at which we were encamped, had formed its channel through sandstone rock; and its narrow bed, containing a ferruginous water supplied by springs, was crowded with high reeds, and shaded with various trees of a dense green foliage. Frogs croaked, and crickets chirped, the whole night; and the call of goat-suckers, and the hooting of owls, were heard in every direction; large fish were splashing in the water; wallabies were bleating as they came down to the creek, and saw our horses; and mosquitoes by their loud humming prevented our sleeping. This noise of animal life during the night formed an agreeable contrast to the dead silence which we had observed at almost all our camps around the gulf, with the exception of the one occupied on the 1st September, and of that at the Marlow, where the flying-fox was the merry reveller of night. Sept. 10.--We were again too late for low tide, to cross at the fishery of the natives, and consequently travelled about two miles and a half higher up, passing in our way three other fisheries; where we crossed the river, the bed was very wide, and covered with shrubs, shingle, and blocks of sandstone; but its rapid stream of fresh water was only about fifteen or twenty yards broad, and three feet deep. At the left side of the river, we saw four or five fine Cycas palms, from eight to ten feet high, and the stem from six to nine inches in diameter. High rocky sandstone ridges extended on the same side, in a direction parallel to the river, and at the distance of two or three miles. They were covered with scrub, open box, and stringy-bark forest; and the wallabi and kangaroo tracks going down to the river, were very numerous. The appearance of the Cypress pine, which formed groups within the stringy-bark forest, and particularly on the rises and sandy slopes, was of a most striking character. A new species of Grevillea, and also of Calythrix, were found in blossom. Beyond the ridges, the stringy-bark forest was obstructed by the leguminous shrub with broad stem (Bossiaea). Several Pandanus creeks went down to the north-east; and the second contained a little water. After travelling about twelve miles to the north-west by north, we encamped at a fine creek with large pools of water, in lat. 16 degrees 21 minutes. During the night, we heard the well-known note of what we called the "Glucking bird," when we first met with it, in the Cypress pine country, at the early part of our expedition. Its re-appearance with the Cypress pine corroborated my supposition, that the bird lived on the seeds of that tree.
