reached our camping ground our day's work was only about to commence. We were not long in obtaining enough water for ourselves, such as it was--thick and dirty with a nauseous flavour--but first we had to tie the horses up, to prevent them jumping in on us. We found to our grief that but a poor supply was to be expected, and though we had not to dig very deep, yet we had to remove an enormous quantity of sand, so as to create a sufficient surface to get water to run in, and had to dig a tank twenty feet long by six feet deep, and six feet wide at the bottom, though at the top it was much wider. I may remark--and what I now say applies to almost every other water I ever got by digging in all my wanderings--that whenever we commenced to dig, a swarm of large and small red hornets immediately came around us, and, generally speaking, diamond birds (Amadina) would also come and twitter near, and when water was got, would drink in great numbers. With regard to the hornets, though they swarmed round our heads and faces in clouds, no one was ever stung by them, nature and instinct informing them that we were their friends. We worked and waited for two hours before one of our three horses could obtain a drink. The water came so slowly in that it took nearly all the night before the last animal's thirst was assuaged, as by the time the third got a drink, the first was ready to begin again, and they kept returning all through the night. We rested our horses here to-day to allow them to fill themselves with food, as no doubt they will require all the support they can get to sustain them in their work before we reach the distant mountain. We passed the day in enlarging the tank, and were glad to find that, though no increase in the supply of water was observable, still there seemed no diminution, as now a horse could fill himself at one spell. We took a stroll up into the rocks and gullies of the ridges, and found a Troglodytes' cave ornamented with the choicest specimens of aboriginal art. The rude figures of snakes were the principal objects, but hands, and devices for shields were also conspicuous. One hieroglyph was most striking; it consisted of two Roman numerals--a V and an I, placed together and representing the figure VI; they were both daubed over with spots, and were painted with red ochre. Several large rock-holes were seen, but they had all long lain dry. A few cypress pines grew upon the rocks in several places. The day was decidedly hot; the thermometer stood at 100 degrees in the shade at three o'clock, and we had to fix up a cloth for an awning to get sufficient shade to sit under. Our only intellectual occupation was the study of a small map of Australia, showing the routes of the Australian explorers. How often we noted the facility with which other and more fortunate travellers dropped upon fine creeks and large rivers. We could only envy them their good fortune, and hope the future had some prizes in store for us also.
