Through treaties with foreign governments and increased activities of the Coast Guard, revenue agents, district attorneys and enforcement agents effort is being made to prevent these violations.  But the Constitution also puts a concurrent duty on the States.  We need their active and energetic cooperation, the vigilant action of their police, and the jurisdiction of their courts to assist in enforcement.  I request of the people observance, of the public officers continuing efforts for enforcement, and of the Congress favorable action on the budget recommendation for the prosecution of this work.

WATERWAY DEVELOPMENT

For many years our country has been employed in plans and M for the development of our intracoastal and inland waterways.  This work along our coast is an important adjunct to our commerce.  It will be carried on, together with the further opening up of our harbors, as our resources permit.  The Government made an agreement during the war to take over the Cape Cod Canal, under which the owners made valuable concessions.  This pledged faith of the Government ought to be redeemed.

Two other main fields are under consideration.  One is the Great Lakes and St. Lawrence, including the Erie Canal.  This includes stabilizing the lake level, and is both a waterway and power project.  A joint commission of the United States and Canada is working on plans and surveys which will not be completed until next April.  No final determination can be made, apparently, except under treaty as to the participation of both countries.  The other is the Mississippi River stem.  This is almost entirely devoted to navigation.  Work on the Ohio River will be completed in about three years.  A modern channel connecting Chicago, New Orleans, Kansas City, and Pittsburgh should be laid out and work on the tributaries prosecuted.  Some work is being done of a preparatory nature along the Missouri, and large expenditures are being made yearly in the lower reaches of the Mississippi and its tributaries which contribute both to flood control and navigation.  Preliminary measures are being taken on the Colorado River project, which is exceedingly important for flood control, irrigation, power development, and water supply to the area concerned.  It would seem to be very doubtful, however, whether it is practical to secure affirmative action of the Congress, except under a Joint agreement of the several States.

The Government has already expended large sums upon scientific research and engineering investigation in promotion of this Colorado River project.  The actual progress has been retarded for many years by differences among the seven States in the basin over their relative water rights and among different groups as to methods.  In an attempt to settle the primary difficulty of the water rights, Congress authorized the Colorado River Commission which agreed on November
