There has been a rapid and progressive decline in the quantity of 
foreign lead smelted in the United States since 1911, owing to the 
unsettled conditions in Mexico. A similar decline appears in foreign 
exports. For the current year the exports of bonded lead will ap 
parently not be more than one-third as much as in 1913 and about 
one-seventh as much as four years ago. The stock of foreign lead 
of all kinds remaining in warehouse June 30, 1914, was 7,237 short 
tons, principally at New York and El Paso. 
For many years prior to 1914 there have been no exports of 
domestic lead ore, bullion, or pig lead. Manufactures only of domes 
tic lead have been exported. During the first seven months of 1914 
the London price of lead has averaged 4.130 cents a pound, against 
3.962 cents, the price at New York. The difference in March, June, 
and July was about 0.3 cent a pound. By August 19 the London 
price had increased to 4.875 cents a pound, a full cent above the 
New York price. Commencing with March, there have been impor 
tant exports of domestic lead to Europe, as follows :

The exports up to and including June went principally to con 
tinental Europe, a little going to Russia, as indicated in the table 
below, but with the differential between London and New York 
prices which obtained in the middle of August, lead will no doubt be 
exported to London.
