The results of the investigations by the Ashburton Power Board regarding the different kinds of poles used for its transmission lines were detailed at one of the meetings held in connection with the board’s loan proposals (states the “Guardian”). Three kinds of poles have been used—biuegum. hardwood and steel. Of bluegum 9281 poles, costing X 7420, have been used; 357 G hardwood, cost A 10.450; and 3575 steel, cost A14,G10; totals, 16,432 poles, .cost £32,480. In other ’ words. 56 1 per cent, of tile poles erected were bluegum, but they represent only 23 per cent, of the total value. With an average cost of 16s. for bluegum. 58s. 6d. for hardwood, and 82s. for steel, it is apparently more economical to use bluegum, despite its comparatively short life. Forestry experts have assured the board that it its obtains an average life of six years only from its gum igfles, their use will prove economical. Many of the bluegum poles erected by the board have been up nearly five years, and from the results already gained it would appear that they are going to BW. satisfactory.
