Payment of Bounties 377 3. If at any time it appears, to the satisfaction of the Governor in Coun- cil, that the charges for transportation and treatment of lead ores in Canada are excessive, or that there is any discrimination which prevents the smelting of such ores in Canada on fair and reasonable terms, the Governor in Coimcil may authorise the payment of bounty, at such reduced rate as he deems just, on the lead contained in such ores mined in Canada and exported for treatment abroad. 4. If at any time it appears, to the satisfaction of the Governor in Council, that products of lead are manufactured in Canada direct from lead ores mined in Canada without the intervention of the smelting process, the Governor in Council may make such provisions as he deems equitable to extend the benefits of this Act to the producers of such ores. 5. The said bounties shall cease and determine on the 30th June, 1908. 6. The Governor in Council may make regulations for carrying out the intention of this Act. 7. Chapter 8 of the Statutes of 1901, intitled "An Act to provide for the payment of bounties on lead refined in Canada, " is repealed. Index 379 INDEX.
