§ Mr. Berryasked the Minister of Agriculture whether his attention has been directed to the large amount of spent carbide sludge there is in the country; and whether, in view of the successful use of this in Algeria, he will endeavour to make arrangements for its use in this country on the land.

Apart from its cheapness it has little to commend it in comparison with other liming materials, such as ground limestone and ground chalk.
