Great Lakes.
Traffic moving through the canals at Sault Ste. Marie—which
includes a very large part of the Great Lakes commerce—in 1925
was 81,875,000 tons of cargo, an increase of almost 10,000,000 tons
over the preceding year, but 9,500,000 tons less than in 1923. The
decline between 1923 and 1924 had been principally in ore and coal.
The increase in 1925 was in ore cargoes, which were over 25 per cent
greater than in 1924. Iron ore and coal accounted for 81.5 per cent
of the total traffic in 1925, wheat and grains approximately 16.7
per cent, while general merchandise was less than 1 per cent of the
total shipments.

Mississippi and Warrior Rivers.
The Mississippi and Warrior River barge lines, serving the
Mississippi between St. Louis and New Orleans and the Warrior
River between Birmingham, Cordova, and Mobile, have been operated
by the Federal Government since 1918. During 1925 there were
910,755 tons of cargo carried by the Mississippi line and 231,464 tons
by the Warrior River line. There has been a steady increase in the
amount of traffic carried by the Mississippi section during 1923, 1924,
and 1925. On the Warrior River the southbound (down) shipments
of coal in 1925 decreased greatly and despite increases in other items
the total southbound traffic was less than in 1924 by over 23,000
tons, Shipments northbound increased bv more than one-third.
