§ MR. COGHILL (Stoke-upon-Trent)I beg to ask Mr. Chancellor of the Ex- 246 chequer if he has considered the advisability of imposing a duty on the export of china and ball clays from this country.
§ THE CHANCELLOR OF THE EXCHEQUER (Mr. AUSTEN CHAMBERLAIN, Worcestershire, E.)Yes, Sir, I looked into this question recently. The export of china and ball clays, though increasing, does not reach half a million tons a year, and the revenue derivable from even a high ad valorem export duty would be insignificant. But the course of the export figures shall be watched.
