The output for 1931 (2,157,756 tons) is 384,336 tons less than that of 1930, and is the largest yearly decrease so far recorded. There was a steady increase since 1922 until this year. In the Northern District there was an increased output of 68,587 tons consequent on the steamdriven power plant at Auckland being required to generate current while the hydro-electric-power station at Arapuni was under repair. In common with the rest of New Zealand the northern miners, owing to the decreased demand, suffered a great deal of idle time, but it is pleasing to record that there was little stoppage owing to labour disputes. Erom the West Coast District the output was 395,577 tons less than that of the previous year, that decrease being due chiefly to the restricted use of bituminous coal and to frequent stoppages owing to petty labour disputes. The demand for coal for railway use is still much restricted owing to the trade depression, and there seems little likelihood of any improvement in that direction for some time. In the Southern District the output shows a decrease of 57,346 tons. That decrease is most noticeable at mines supplying the better grade of household fuel, as the community is purchasing the cheaper fuels and farmers are even sawing down fir and other trees for domestic fires. Much idle time was experienced at the Kaitangata and Oliai Mines, and at most of the latter the miners are still sharing the available work. The production from and the number of persons employed at the collieries of the Dominion are shown in the following table : —
