The Drug Convention An International Convention for the Limitation of

the Manufacture of Narcotic Drugs has been signed at Geneva by the' representatives of twenty-eight States, and will be applied as soon as it can be ratified by twenty- five, including four manufacturing countries. By its terms manufacturing countries may obtain what trade they can, but if the total amount manufactured exceeds the total which can be shown, on the basis of the estimates supplied by all signatories, to have been manufactured for legitimate purposes, " such excess shall be deducted from the amount to be manufactured during the coming year." It is needless to point out how this would affect countries whose production sometimes exceeds the world's legitimate needs. But all is not over with the signature' of the convention. It may take many years to make effective, since this abominable traffic in quanti- ties beyond the proper needs is in the hands of clever and quite unscrupulous men.
