The writer points out that the yerba mate problem in Argentina 
is one "of over-production, aggravated by continued importation" 
and that Argentina, Brazil and Paraguay are 'reducing their output 
of the product. "The problem as a '/hole, i.e. as affecting all 
three producing countries, is one which seems to call for the 
greatest possible measure of cooperation among those countries, 
aiming primarily at finding new markets, and at the more inten- 
sified and assiduous 'cultivation 1 of the. markets at present 
beinn; catered for."
