OF A. right to the limestone was not admitted and, further, at the trial
before Ferguson J. the verdict, on the basis of his Honor's ruling
HAZELDELL that the limestone could not be included, was by consent, taken at
£1,200. Let these circumstances cancel each other, and look at the affirmative evidence on the limestone basis.
On 1st January 1915 the hypothetical prospective buyer would A.C.J. know that there were in this land within thirty miles of the Capital
somewhere about 6,000,000 tons of good quality limestone with shale reasonably near, and a good water supply, a short distance for a railway to the main line, and a good prospect of a railway to the coast. There was a practical certainty of the Commonwealth requiring 10,000 tons of cement per annum for several years, and a fair probability of a considerable population in the Federal Territory requiring cement also. There were advantages and disadvantages, compared with outside cement works, but certain important broad facts presented themselves. There was a great, constant and growing demand for cement in New South Wales, a demand that was not overtaken by the supply. Prices had gone up, and, though production was slightly diminishing, the evidence is that the works were producing all they could. Prices may or may not have been the result of a combine, but the fact is they were up and stayed up the Necessary Commodities Board had fixed the price at 108s. ton, and the lowest price at which the Commonwealth could, as a favoured customer, get cement at Canberra was 14s. 9d. a cask. There is evidence that, for a production of 100,000 casks a year, the average cost to the manufacturer would be about 8s. 3d. a cask at the factory with 7d. additional for transport to Canberra. True, the evidence seems to show that 120,000 casks would be the lowest profitable output. That would, of course, reduce the average cost, but, as there is no direct evidence what that would be, Dr. Brissenden accepted the average cost on the 100,000 cask basis. To that the prospective buyer must add something for interest on capital cost of land and depreciation, and, after a not illiberal allowance, something over 1s. a cask is to be added to the 8s. 3d., say 9s. 6d. in all, if £12,500 be taken as the cost of the land. Having regard to the possible demand, the chances of other supplies competing, the chances of some enterprising manufacturer stepping in and offering
