I took the boat in the afternoon at high-water to proceed to the encampment, which we were then able to approach within a quarter of a mile. It was situated in the depth of a creek, into which a clear and sparkling stream of fresh water poured its abundance: the shore was formed of enormous granite boulders, which rendered it hardly accessible except at high-water; and the red sandstone platform which is here the nature of the coast, was abruptly intersected by one of those singular valleys which give so marked and so distinctive a characteristic to Australian geology. The separated cliffs approach to within about a quarter of a mile of each other, and then--still preserving their precipitous form--recede some three miles inland, in a southerly direction, and there rejoining, make any passage from Walker's Valley* to the interior a barely practicable feat. (*Footnote. So named by Lieutenant Grey to commemorate the services rendered by the surgeon of his party in finding a road from it to the interjacent country.) TIMOR PONIES. The encampment consisted of a few roofless huts, placed irregularly upon a carpet of rich grass, whereon six Timor ponies were recruiting after the fatigues of a journey in which they appeared to have borne their full share of privation and danger. Their marketable value was indeed but small, and Lieutenant Grey had, therefore, determined to leave them behind in the unrestrained enjoyment of their natural freedom. My visit was made after the encampment had been finally abandoned, and the thought that a little spot once tenanted by civilized man was about to be yielded to that dreary solitude from which for a while he had rescued it, made the pilgrimage a melancholy one. The scene itself was in strict keeping with such thoughts--the rugged and lofty cliffs which frown down upon the valley--the flitting shadows of the watchful eagles soaring far over my head--and the hoarse murmurs of the tide among the rocky masses on the beach--ail heightened the effects of a picture engraven on my memory too deeply for time itself to efface.
