These improvements are now proceeding upon an unprecedented scale. Some
indication of the volume of work in progress is conveyed by the fact that
during the current year over 380,000,000 cubic yards of material have been
moved--an amount equal to the entire removal in the construction of the
Panama Canal. The Mississippi waterway system, connecting Chicago, Kansas
City, Pittsburgh, and New Orleans, will be in full operation during 1933.
Substantial progress is being made upon the projects of the upper Missouri,
upper Mississippi, etc.
Negotiations are now in progress with Canada for the construction of the
St. Lawrence Waterway.
