ENGINEER-MANAGER'S REPORT The engineer-manager reported as follows lor tlie month of July : Line Erection.—2.oß route miles of 11,000 volt lines. 1.02 route* miles of -!00 volt on ] 1,000 volt lines. 1 11,000' volt air break switch erected at Matatu. Also two transformers complete with structures. l(ji route chains of -100 volt on 11,000 volt and 12.0 chains of 400 volt line changed from No. g copper to 7/080 copper.

One transformer and structure removed from pole 23 and re-erecte:l on pole 27A, AVaimana feeder. The uoove alterations were neecssary to provide fnj new consumers and increased loading. Consumers’ Service Lines: 20 new service lines completed totalling 124. S roe.to chains of lines. Also J services of 24.2 chains rearranged, and J amcuntiiig to 10.64 c hains changed L.mn single phase to 'J phase. Maintenance Lines: Earth testing completed in both areas. Tree cutting earned out in both areas. A .number o', subs together with equipment has boon inspected and overhauled whore required. On these structures 12 j. in insulators, 1 set. of 11,000 volt loses, and one cross-arm were repiar-

During the month two traiv-ferm-ivs wen* damaged by lightning aim bad to be ienlaced. The repeated inti rruptio-ns to supply on the Ipotdci feeder has at last been rectified, and was caused by tin* partial failure of a:- 11.009 volt insulator located on the Tirolmnga section. Further nminlemtnce v. ork necessitated, the replacement of one .11,000 volt curuiit t: ansfor 1111*1" and one set of I 1,000 volt line luses.

As sin experiment to reduce radio interference. 9 11,000 volt strain and 3 JI,OOO pin insulators wore replaced, lids work was carried out in conjunction with tests made by the R. and T. Department’s. radio inspector. Two consumers’ service lines overhauled and repaired. Consumers’ Connected to 31st. July.

P.W.IX Supply: For the above month there were ,two shut-downs on AYaiotnhi Sub. totalling 2 hours 45 mins, and two on Edgecombe Sub. totalling 2 hours 21 mins. All were by arrangement and necessary for the placing in service of new equipment housed in tlie respective sub-stations. General: A further native block in the Opape district has boon canvassed an<] an approximate estimate resulting from a preliminary survey indicates he following:—Approx—l.o miles 11.000 vol lilies'. 1 mile 400 volt lines. 4 transformers. 'Tin* total capital cost including meters and a proportion of service line, £9OO. Guaranteed revenue £IOO p.a. 17.7 per annum.
