There will be noticed a decline in the production of the United States
during the year 1910, resulting from the present movement to restrict
output whilst the large accumulated stocks of metal are being absorbed.
The movement is probably more or less temporary, and is being largely
directed by American financiers who are endeavouring to bring about an
international agreement on the subject.
