HC Deb 14 June 1928 vol 218 c1155
25. Major OWEN

asked the Minister of Health whether slate quarries and slate mines are included in the category of productive industries under the terms of the Rating and Valuation (Apportionment) Bill?

Mr. CHAMBERLAIN

I may refer the hon. and gallant Member to Clause 3 of the Bill, under which industrial hereditaments are classified under mines and factories and workshops. The expression "mine" includes all mines of whatever description, and under the Factory and Workshops Act all quarries are factories or workshops.
