The decline in the annual output was chiefly due to restriction of work by miners at the principal collieries. The output per person employed below ground has declined from 750 tons during 1916 to 648 tons during 1919. The number of operative collieries was 138, of which the 16 most productive won 1,-175,789 tons, being an average of 641 tons per person employed below ground; the 122 smaller collieries, where little or no restriction occurred, produced 472,059 tons, being an average of 671 tons per person employed below ground. As the principal collieries are better developed and equipped for a larger production per miner than are the smaller collieries, the fact that the latter have produced more coal per miner during 1919 appears to be conclusive evidence as to the chief cause of the decline of coal-output for the Dominion. No new colliery arrived at the output stage during the year. The production from and the number of persons employed at the collieries of the Dominion are shown in the following table : —
