ELECTRIC POWER POLES.

EXPERIMENT BY, A BOARD

A little over three years ago tlu Thames Valley- Power Board decided to experiment, and find out which species of eucalyptus tree made the most satisfactory power pole and which preparation preserved the timber in the ground the longest (says the Morrinsville Star). A plot of ground on the chairman’s farm, Mangaiti, was used fpr the purpose, and in all 103 log? were erected and tabulated. Six different varieties of eucalyptus were used, the trees being obtained from the Forestry Department, Rotorua.' Some of. the logs were treated with creosote and tar and other preparations, thirty different methods being used, while others were erected without any treatment. The members of the board, accompanied by the engineer and manager, visited the plot on Tuesday and made observations on the condition of the different poles and treatment. Generally speaking poles that* had been treated were in better condition than poles-that had not been treated. The engineer said that this fact should not be taken as conclusive as when the treated poles started to decay they might go quicker • than the untreated ones. The most satisfactory treatment seemed to be two coats of hot creosote compound, poles thus treated showing the best condition, after three years.

Included in the plot were a number of eucalyptus eugeniodides, of which the Power Board has planted a large area at Iverepeehi for future requirements. This variety stood up -to the experiment very well, particularly the stumps treated with the , creosote compound.
