PROBLEM FOR ENGINEERS.
WATER RACE DIVERTED. Per Press Association. ASHBURTON, July 19. Slipping country on the Surrey Hills has necessitated the changing of the course of the ltangitata diversion race for a mile and a-linlf. The slip, on tho property of Mr A. N. Grigg, M.P., is a quarter of a million yards and is moving at the rate of an inch a day. Hon. R. Semple yesterday authorised a plan whereby, from a safe distance from the slip, the water will drop through pipes to the down country a hundred yards below the level of tho abandoned race and under a 13ft head he forced up to a hillside race bevond the danger point. The pipes will he the largest in the Southern Hemisphere and will have an inside diameter of 12ft. the shell, in which probably lin steel reinforcements will bo used, having a thickness of lOin. The department proposes to make the pipes at Surrey Hills. Each 10ft section will weigh 23 tons. The change of plans will not delay the completion of the diversion. The Minister announced that the Lake Tekapo storage development and hydro-electric power scheme would be begun in three or four months.
