Sometimes six or eight ewes may be seen running to a particular spot on the pasturage, about the roots of clumps of grass, and sometimes those of fallen trees, licking and gnawing about the spot, as if it had a similar earth to that found in the _water holes_. They will burrow underneath the bank, to get the saline earth, at those places where it may be most moist. This quality of the ground is supposed by the shepherds to be more prevalent about _limestone ranges_ than any other geological formation; but I cannot consider this as satisfactorily proved. Although it has prevailed, for the most part, in places at which the limestone has formed the principal geological character, yet there are other parts of the country, where sheep have manifested a similar morbid appetite, when no limestone has existed. An ewe being missing about some limestone ranges, was seen coming out of a small cavern, in which she seemed to have found some of the saline earth, as she had a quantity of earth about the mouth; and the place was afterwards much frequented by other ewes, until they were removed from the spot. The sufferers in the loss of lambs and ewes from this morbid appetite of the latter, are principally Messrs. Dutton, O’Brien, Warby, Hume, Manton, &c., all having sheep-runs about the Murrumbidgee country. Mr. Dutton addressed a letter to the government on the subject, with the intention of getting his grant of land, if possible, changed to some other part of the country. The following is an extract from his letter, which clearly points out the destructive effects produced among the flocks, the most valuable stock of the settler in this colony, and on which his prosperity greatly depends. “The disadvantages which I have thus to detail to you, arise from the novel disease with which the sheep are affected. It appeared after the first lambing, and within four months from the time of my occupation of the land in question. Its unaccountable and destructive nature renders my selection utterly useless. The nature of the disease, as far as I have yet remarked, is as follows:—The sheep, in the first place, devour the earth ravenously, the pasture being at the same time luxuriant, principally rib-grass, and other succulent herbs; they become speedily emaciated, from this unnatural diet, more particularly as the lambing season advances, and when lambing commences: the other ewes surround the one lambing, and devour the young as they emerge from the mother. The lambs saved through the care of the shepherds become poverty stricken, from the low condition of the mothers, and generally die before they become a month old. Thus, instead of having twelve hundred lambs this season, as my regular increase, I do not count four hundred; besides a very great decrease from mortality in the maiden sheep, originally purchased at high prices. The number of shepherds required being at the same time thrice beyond the proportion usual in the colony.”—November 1832.
