asked the Minister of Works what are the estimated requirements of cement per month for the hydroelectric schemes, for factory building, for house building and for other purposes, respectively.

The estimated monthly requirements in Scotland for hydro-electric and other power stations are about 12,000 tons, and about 20,000 tons for housing. Forty thousand tons a month are supplied for other purposes.

May I ask my hon. Friend, in view of these figures, whether he is still satisfied that there is sufficient cement going to Scotland?

There has been more than a 30 per cent. increase in the supply of cement over the last few months.

But in spite of the 30 per cent. increase, there is still a shortage.
