The friendly relations and the extensive, commercial intercourse with the Western Hemisphere to the south of us are being further cemented by the establishment and extension of air-mail routes. We shall soon have one from Key West, Fla., over Cuba, Haiti, and Santo Domingo to San Juan, P. R., where it will connect with another route to Trinidad. There will be another route from Key West to the Canal Zone, where connection will be made with a route across the northern coast of South America to Paramaribo. This will give us a circle around the Caribbean under our own control. Additional connections will be made at Colon with a route running down the west coast of South America as far as Conception, Chile, and with the French air mail at Paramaribo running down the eastern coast of South America. The air service already spans our continent, with laterals running to Mexico and Canada, and covering a daily flight of over 28,000 miles, with an average cargo of 15 000 pounds. WATERWAYS Our river and harbor improvements are proceeding with vigor. In the past few years Ave have increased the appropriation for this regular work $28,000,000, besides what is to be expended on flood control. The total appropriation for this year was over $91,000,000. The Ohio River is almost ready for opening; work on the Missouri and other rivers is under way. In accordance with the Mississippi flood law Army engineers are making investigations and surveys on other streams throughout the country with a view to flood control, navigation, waterpower, and irrigation. Our barrier lines are being operated under generous appropriations, and negotiations are developing relative to the St. Lawrence waterway. To Secure the largest benefits from all these waterways joint rates must be established with the railroads, preferably by agreement, but otherwise as a result of congressional action. We have recently passed several river and harbor bills. The work ordered by the Congress not, yet completed, will cost about $243, 000,000, besides the hundreds of millions to be spent on the Mississippi flood way. Until we can see our way out of this expense no further river and harbor legislation should be passed, as expenditures to put it into effect would be four or five years away. IRRIGATION OF ARID LANDS
