Lieut.-Colonel Sir F. HALL:

asked the Minister of Health if he can state the average number of bricks laid by a bricklayer in this country prior to the War and at the present time in Great Britain and the United States, respectively; if he is aware that certain of the principal trade unions in the building trade have placed a limitation on the output of their members; if this policy is partly responsible for causing the delay in carrying out the national housing policy that is so urgently called for and increasing the cost of providing houses to an extent which makes it difficult for the local authorities concerned to provide adequate housing accommodation; and if he will state what action the Government are taking to secure the measure of production by the workpeople concerned if the housing problem is to be solved with due expedition and reasonable economy?
