The following table summarizes the results of the year's operations in connection with electric supply throughout the Dominion, and Tables X and XI show the financial statistics for each supply authority. It should be noted that the method of compilation and computation adopted for the following table is slightly different to that of years previous to 1933 :

GROWTH OE LOAD. The total connected load at end of the year under review was 1,228,814 kw., comparedVith 1,149,173 for 1934, an increase of 79,641 kw. or 6-93 per cent. Statistics pertaining to the increasing use of electric ranges, electric water-heaters, and milkingmachines, have been collected and scheduled for some years past, and from the following table wdl be seen the annual growth which has taken place in each class: —

See Table XIV for details for year ended 31st March, 1935.

BROKEN WIRES AND POLES. Gales of exceptional severity, accompanied in some instances by heavy snowstorms, occurred in various parts of the Dominion during the past year and account for the large number of breaks reported. There were 2,204 broken wires reported by electric-supply authorities, with 106,336 miles of conductor erected. The corresponding figures for the previous year were 1,613 broken wires, and 98,854 miles of conductor in use. Falling trees were again the principal cause of the breaks, and accounted for. 26'6 per cent, of the total, as against 16-25 per cent, for 1934. As regards broken poles, 519 instances were reported for the year, of which 365, or 70'4 per cent., were New Zealand blue-gum. For 1934 the total number of broken poles reported was 417, and it is still evident that electric supply authorities who experimented with New Zealand blue-gum and nondescript Australian " hardwoods " are now being called upon to make replacements sooner than the anticipated life of fifteen years for poles used on distribution-lines.
