IBBIGATION—CENTBAL OTAGO. Operation op Completed Schemes. During the past year the several completed schemes have been maintained in good condition, and all lands requiring water have been supplied. Of the schemes in operation, the following nine were operated during the year on a trading basis : Ida Valley, Galloway, Teviot, Bengerburn, Ardgour. Tarras, Earnscleugh, Manuherikia, and Last Chance ; as against four for the preceding year. The financial results of the year's operations were : Bevenue, £13,726 ; working-expenses, £11,089 ; profit on working, £2,637 —the profit representing a decrease of £1,4-73 as compared with last year. The reasons for this decrease are, firstly, the inclusion in the trading accounts of the five additional schemes, in which irrigators are as yet paying only on the lower scale of the graduated rates ; and, secondly, the general reduction in rates following on the adoption of the Irrigation Committee's recommendations.
