Another trouble of the squatter, the silting up of his fences with leaves and dust in the hot weather, until they disappear and sheep and cattle stray over them unimpeded, is also being successfully overcome. On one estate enormous machines like snow-ploughs were shown, which were periodically pulled by horses along the windward side of fences subject to this mishap. Floods come only occasionally, but the squatter has declined to allow himself to be defeated by them. The Prince saw the bones of many a stray sheep that had been drowned in the last visitation of this kind. It is indeed extraordinary that such a thing should occur upon a table-land two thousand feet above sea level, where rain is ordinarily so scanty that drought is continually feared. The very rarity of heavy rain, however, makes the conditions such that the water-courses may be inadequate to carry off any sudden downpour, with the result that the flooding, when it does occur, may easily be very extensive, as the country for hundreds of miles on end is almost absolutely level. Motor-cars have been used successfully to convey thousands of sheep, three or four at a time, from flooded areas to banks where they could exist until the water subsided. In other cases boats have been brought from incredibly distant rivers to carry stock to safety. Much has also been done upon men's backs, for the squatter does not allow his sheep to perish if anything within human strength can help them. In this part of Australia the grass is so thin that from two to five acres are required to support each sheep. This accounts for the immense size of the runs, which extend in some cases to hundreds of thousands of acres. One of the results of so much grazing space is that epidemics are almost unknown. On one of the runs the Prince took a hand, with power-driven clippers in sheds, where one man shears, on the average, more than a hundred sheep in a single day, the wool fetching up to twenty-two pence a pound. Fleeces so ticketed indicate the neighbourhood of the wool millionaire, and he was to be met in all stages of opulence. A run carrying fifty thousand sheep, each yielding a profit of ten shillings in the year for wool alone, is by no means uncommon in this part of Australia, men who had established themselves in pre-war days, in quite a modest way, upon land leased from the State, not infrequently finding their incomes multiplied a number of times over as the rates for wool increased. The greater part of these profits has remained in the country, and much of it has been put into the development of the runs, and the improvement of the breeds of sheep, horses and cattle on them. In one of the stations a five-thousand-pound bull had recently been bought, and cows were valued at a thousand pounds apiece. On another, three rams were shown to the Prince which were considered to be worth six thousand pounds, being an average of two thousand each.
