Brackish water is not pleasant to drink, but it is not necessarily unhealthy. Personally, I am a great believer in the compensating laws of Nature in preference to the ill-balanced habits of civilised men, and am certain that the best thing one can drink in the desert, under the abnormal conditions of heat, dust and dryness, is salt water, which stimulates digestion and keeps the system clean. Of filters, condensing apparatuses, soda-water cartridges, and other such appliances for difficult land travelling, the less said the better. They are very pretty toys, the glowing advertisements of which may add to the profits of geographical magazines, but they are really more useful in cities in Europe than practical in the desert. Possibly they may be a consolation to a certain class of half-reasoning people. But anything else, it might be argued would serve equally well. One sees them advertised as preventatives of malarial fever, but no sensible person who has ever had fever or seen it in others would ever believe that it comes from drinking water. Fever is in the atmosphere—one breathes fever; one does not necessarily drink it. When the water is corrupted, the air is also corrupted, and to filter the one and not the other is an operation the sense of which I personally cannot see.

It has ever been my experience, and that also of others, that the fewer precautions one takes, the more one relies on Nature to take care of one instead of on impracticable devices—the better for one's health in the end. I do not mean by this that one should go and drink dirty water to avoid fever,—far from it,—but if the water is dirty the best plan is not to drink it at all, whether filtered—or, to be accurate, passed through a filter—or not, or made into soda-water!

One fact is certain, that if one goes through a fever district one can take all the precautions in the world, but if one's system is so inclined one is sure to contract it; only the more the precautions, the more violent the fever.

But to return to our specific case, brackish water is not necessarily dirty, and as I have said, is to my mind one of Nature's protections against fever of the desert. In my own case, when I partook of it freely, it decidedly kept the fever down.

We made a much earlier start, at 8 p.m., on November 13th, and I had to walk part of the way as it was too steep for the camels. We had great trouble in taking them down to the dry river-bed—which we were to follow, being quite flat and therefore easier for the animals. We went along between low hills, getting lower and lower, and some two miles from the Darband tower we emerged into the open, the river-bed losing itself here in the desert.

During the night of the 13th-14th we travelled 28 miles on the flat until we came to more low hills, which we entered by another river-bed, also dry. We had come in a north-north-east direction so far, but we now turned due east among high, flat-topped hills which resembled a mass of ruined Persian houses of a quadrangular shape, so strangely had they been carved out by the corrosive action of water. They were of solid rock, and eaten into holes here and there, which from a distance gave the appearance of windows and doors, and of caves.

The river-bed on which we travelled was of soft sand—very troublesome—and minute gravel strewn here and there with large boulders fallen from the cliffs at the sides. Cairns had been erected in various prominent points by caravan men, to show future travellers the way to Naiband for Birjiand and Meshed.

Following this in an easterly direction we came to a large basin, and then further on to another. We continued in zig-zag for a short distance, when we arrived at a place where the river-bed makes an elbow, turning to the north. At this spot a caravanserai was in course of construction, built at the expense of some charitable person. There was only one well of brackish water, and very little of that, too. The workmen would not let us partake of it. Everything, of course, had to be brought, as nothing could be obtained there, and the few workmen complained bitterly of the hardships they had to endure in going on with their work. They feared they would soon run short even of water. They were all fever-stricken, and two quite in a pitiable condition. They had little food left; most of their animals had died, and they were unable to leave. Chel-Payeh was the name of this well (altitude 4,420 feet).

We were thirty-two miles from our last camp, and reached here at 8 a.m. On taking the loads down we had a great disappointment. Sadek, who was not accustomed to ride camels, was suffering considerably, and in order to make himself comfortable he had contrived a clever device to avoid coming in immediate contact with the wooden frame of his saddle. He had fastened the two largest skins we had with our supply of good water on the top of his saddle, and having covered them over with blankets and carpets, on them, he sat and slept through the whole night. Alas! the weight of his body burst both skins during the night and squeezed all the water out!

So here we were, with only two small skins of fresh water left, which would have to last the whole party several days. But we were to have a further misfortune on the following march.
