According to his account, by following it for seven or eight miles, we should get altogether clear of the sandstone ranges, and enter a tract of country of great fertility.

On the 26th Mr.
Walker reported me to be so much better that he thought I might with safety move on the next day on horseback, and preparations were accordingly made for a start.
A very serious change had taken place in our resources in one respect, for only fourteen ponies now remained alive out of twenty-six, and many of these were so weak and in such bad condition as to be almost useless.
On opening one of those which had died about a hat-full of sand was found in its inside, and it therefore appeared very probable that the ponies, having been landed in the first instance on loose sandy soil producing only a short and scanty vegetation, had taken up so much sand with their food as to interfere with the functions of the stomach, and hence had arisen their gradual wasting away and ultimate death.

I indeed entertain no doubt that the great loss of ponies we sustained arose from this cause.
CHANGE OF PLANS.
This reduction in the number of our beasts of burden prevented me from entertaining further hope of being able to proceed for any great distance parallel to the coast in a southerly direction.

I therefore formed a depot at our present encampment, burying all such stores as the remaining ponies were unable to carry on.

My intentions being merely to proceed as far as the supply of provisions we could carry with us would last, then to return to our position, and from thence to the schooner.
DESCRIPTION OF A NEW VOLCANIC COUNTRY.
On the morning of the 27th of February I was, in pursuance of this plan of operations, lifted on my horse, and we moved on in a south-west direction, across sandy plains covered with scrub and a species of stringy-bark; but on travelling for about a mile and a half the character of the country became more rocky and difficult.
