It is no uncommon mistake, with persons who ought to know better, to magnify the toils and hardships endured by the body, while those labours and anxieties that the mind undergoes are disregarded and forgotten. Every man engaged in an exploring party in the bush, for instance, has his severe trials to go through, but their trials are not to be compared to those of the commander of the party. How often when the rest are sleeping must he be watchful? How frequently, while others are gay, must he feel thoughtful! These remarks may easily be applied to the following description of the coast near Shark's Bay, in the N. W. of the island of New Holland. There was great beauty in the scenery, both the sky and the water had that peculiar brilliancy about them to be seen only in fine weather, and in a very warm climate. To the west lay a boundless extent of sea, to the eastward was a low shore fringed with trees, not only down to the water's edge, but forming little green knots of foliage in the ocean itself; behind these trees were low wooded hills, and in front of them were numbers of pelicans and water-fowl. There was only about three feet depth of clear transparent water, through which were seen many beautiful and large shells, and various strange-looking fish, at some of which last one or other of Captain Grey's men would sometimes make an attack, while loud peals of laughter would rise from the rest, when the pursuer, too anxious to gain his object, would miss his stroke at the fish, or, stumbling, roll headlong in the water. The fineness of the day, the novelty of the scenery, and the rapid way they were making, made the poor fellows forget past dangers, as well as those they had yet to undergo. But this was more than their commander was able to do. "My own meditations," adds Captain Grey, "were of a more melancholy character, for I feared that the days of some of the light-hearted group were already numbered, and would soon be brought to a close. Amid such scenes and thoughts we were swept along, while this unknown coast, which so many had anxiously yet vainly wished to see, passed before our eyes like a dream, and ere many more years have hurried by, it is possible that the recollection of this day may be as such to me." Among the wonders of Nature to be met with in the Australian bush, the large rivers occasionally dried up to their very lowest depth by the extreme drought, are very remarkable. Few natural objects can equal in beauty and utility a river in its proper state,-- "Though deep, yet clear; though gentle, yet not dull; Strong without rage, without o'erflowing full;"
