that they thus improve navigation, and that if they do not impair navigation they should be allowed to take for themselves the entire profits of the water-power development. Whatever they may do by way of relieving the Government of the expense of improving navigation should be given due consideration, but it must be apparent that there may be a profit beyond a reasonably liberal return upon the private investment which is a potential asset of the Government in carrying out a comprehensive policy of waterway development. It is no objection to the retention and use of such an asset by the Government that a comprehensive waterway policy will include the protection and development of the other public uses of water, which can not and should not be ignored in making and executing plans for the protection and development of navigation. It is also equally clear that inasmuch as the water power thus created is or may be an incident of a general scheme of waterway improvement within the constitutional jurisdiction of the Federal Government, the regulation of such water power lies also within that jurisdiction. In my opinion constructive statesmanship requires that legislation should be enacted which will permit the development of navigation in these great rivers to go hand in hand with the utilization of this by-product of water power, created in the course of the same improvement, and that the general dam act should be so amended as to make this possible. I deem it highly important that the Nation should adopt a consistent and harmonious treatment of these water-power projects, which will preserve for this purpose their value to the Government, whose right it is to grant the permit. Any other policy is equivalent to throwing away a most valuable national asset. THE PANAMA CANAL During the past year the work of construction upon the canal has progressed most satisfactorily. About 87 per cent of the excavation work has been completed, and more than 93 per cent of the concrete for all the locks is in place. In view of the great interest which has been manifested as to some slides in the Culebra Cut, I am glad to say that the report of Col. Goethals should allay any apprehension on this point. It is gratifying to note that none of the slides which occurred during this year would have interfered with the passage of the ships had the canal, in fact, been in operation, and when the slope pressures will have been finally adjusted and the growth of vegetation will minimize erosion in the banks of the cut, the slide problem will be practically solved and an ample stability assured for the Culebra Cut. Although the official date of the opening has been set for January 1, 1915, the canal will, in fact, from present indications, be opened for shipping during the latter half of 1913. No fixed date can as yet be set, but shipping interests will be advised as soon as assurances can be given that vessels can pass through without unnecessary delay.
