and the supply appears tolerably abundant; it is, however, rather difficult of access towards the end of the dry season, as the water has then to be carried over the rocks in small baracas fifty or sixty yards to the boats, but from the setting in of the rains to the end of August it runs down strongly at high-water mark.  I walked back overland to the camp with Mr. Walcott, the distance being about four miles, heading by the way another deep cove, the margin of which was lined with a broad belt of mangroves.

21st to 28th July.

Was fully taken up in shoeing horses, making spare shoes, refitting and packing stores, etc., ready for our trip to the eastward, my own time being principally taken up in roughly plotting the country already explored, so as to secure all the information obtained, in the event of any accident occurring to my field-books.

29th July.

Everything being in readiness for our departure, I gave Captain Dixon instructions to wait for us in the bay to the 10th December, and in the event of our not then returning, Mr. Walcott would land one of the ship’s iron tanks, and bury in it a quantity of stores, at a spot already agreed upon; the Dolphin would then proceed to Fremantle.  It blew so fresh all the morning that I could not land until 3 p.m., when we quickly saddled up and proceeded three miles to a waterhole up in the volcanic hills, as it was probable we should have a very long day’s march tomorrow without water.  As we had now only nineteen horses, and one of these so low in condition as not to be able to carry a load, we could only take with us eighty-seven days’ rations, at the rate of one pound of flour, seven ounces of meat, and four ounces of sugar per man per diem; we were, however, well provided with ammunition, and thirty spare sets of horse-shoes, with nails sufficient for at least two removes, the horses themselves being shod at starting with extra strong shoes tipped with steel.  We had now only seven saddle-horses, so that one of the party was always on foot by turns of an hour each.  It had been originally intended that the Dolphin should proceed to Roebuck Bay and meet us there; but it was now so late in the season that I did not deem it prudent to run the risk of removing her to an unknown anchorage, where it was possible we might not be able to reach, and thus lay ourselves open to the probability of a very embarrassing uncertainty.  The result proved we had adopted the right course.  Bivouac.

Difficulty in crossing mud flats.

30th July.

This morning we crossed the marsh with some difficulty, as all the pack-horses but three fell and stuck in the mud, until we transferred their loads to our own backs and carried them through half a mile of the softest part.  The operation detained us so long that we did not make more than eighteen miles, when we found a little water left in the pool seen on the 18th.  Camp 48.
