§ Mr. Hastingsasked the Paymaster-General what percentage of sulphur is contained in the principal varieties of smokeless fuels; and how this compares with that contained in an average sample of coal or coke.
§ Mr. MaudlingAbout 1 per cent. by weight in anthracite and from 0.4 per cent, to 7.0 per cent. in coke and other manufactured smokeless fuels, varying with the sulphur content of the coal from which they are produced. The average sample of coal or coke contains about 1.6 per cent. of sulphur.
