asked the Secretary for Mines what is the number of workers employed in the coal mines of Poland; and what are the hours of labour, calculated on the basis adopted in Table 17 of the Report of the Royal Commission on the Coal Industry, 1925, p. 170?

The information is as follows:show whether the figures given in the Report of the Royal Commission on the Coal Industry, 1925, page 57, as to the number of separate undertakings in the Westphalian and the Pas de Calais coalfields still hold good; if not, what changes there have been since the date of that report; and what is now the annual output of each of those coalfields?

The number of separate undertakings in the Rhenish Westphalian coalfields in 1927, the latest year for which information of this kind is available, was 50, and the output of coal in that year was 118,022,086 metric tons. For the current year, the estimated output, based on the first nine months, is 121,750,000 metric tons. In the Pas de Calais coalfield there are 15 separate undertakings and, for the current year, the estimated output, based on the first nine months, is 25,000,000 metric tons.
