We still await the permit from (he Public Works Department to lay the 11,000-volt submarine cabl s in the river bed for the crossing of the Waihou River at Puke and until this permit is received it is not possible to couple up the Hauraki Plains section The Public Works Department has now advised us- that the matter has been referred to the Post and Telegraph Department and we have again urged upon the Public Works Department the necessity of granting

the permit at an early dafc\ A 400-volt line is being constructed on the Rangiora West Road. The survey of the various lines in this area is well in hand. A consignment of pqjes has recently arrived at K ipu and arrangements have been made to land them on the Plains.

has been completed from south of No 2 Road to Wiseman’s road, aud the poling on No. 2 Road has been completed. The wiring of these sections is delayed on account of non.arrival of 3,300-volt insulators. The gang on this section has been employed for a considerable time on unloading and distributing poles. Morrinsville. —The necessary plans have been submitted to the Public Works Department for the use of bare wires in certain parts of the Borough. The whole of the lines in the Borough have been pegged out and poles have been distributed. Matamata Section. *— The main 11,000 volt line has been extended from Matamata to Waharoa and this line was made alive on December 22nd at 5.15 pm. Power is beiDg supplied to the Waharoa Dried Milk Factory. A low tension line has been erected on this section and a number of consumers coupled up.

time assisting the Post and Telegraph

Department in the necessary alter, ations to their lines on the Mats. mata-Waharoa section.

Hinuera-Okoroire-Tirau Section.— A start has been made on the erection of this line from Hopkins’ Corner. For the first two and a-half miles 11,000, 3,300 and 400-volt circuits will be carried on the same poles. The poles have been erected for a distance of about 6 miles from Hopkins’ Corner and are now near Okoroire station.

A 100 k.v.a. transformer, 11,000 to 3,300 volts with the necessary switch gear has been erected at Hopkins Corner. All switch gear on the route between Horahora and Mafamata has been so arranged that a minimum of trouble will be experienced in making further connections to this main line. General—Work has been somewhat delayed owing to non-delivery of material, chiefly 11,000 and 3,300volt insulators and copper wire. A consignment of 11,000-volt insulators has now arrived and we have sufficient copper wi»e in hand for present requirements whilst a fuitherlot has been on order tor some time. We still await delivery of 3,300-volt insulators but hope to have some in hand shortly.

All transformers to hand have been dried out at Ruakura sub-station with satisfactory results. A. few porcelains bushings and one cover have been broken in transit and we have advised the agents and made the necessary claims. Two transformers have broken down under service and we recommend that those be forwarded to the Public Works Department substation at Ruakura for an indepentlftet leport so that in case there is any. indication of inferior workmanship oPjnaterial a claim may be put in to the nickers.
