Three Volumes Of AWO's Waterway Economics Reprinted For General Distribution The American Waterways Operators, Inc. has published and is making available for gen- eral distribution a reprint in pamphlet form of 11 issues of Volumes II through IV of Waterway Economics, the Association's bul- letin of fact and interpretation. The 11 issues making up Volumes II, III, and IV were originally published individually during the period of October 1967 through Oc- tober 1969. They cover the subjects of "Water- way User Charges and Marginal Cost Pric- ing" ; "Waterway Transportation and Natural Resources for a Growing Economy"; "The Benefit-Cost Ratio, the Rate of Interest, and Water Resource Policy"; "The Coming Trans- portation Crunch and the Potentials of Barg- ing Technology"; "The Multi-State Commun- ity of Interest in a Water Resource Project"; "The Inland Waterways and Economic Growth"; "Coming Role of Barging in Marine Container Operations"; "Potentials of the 'Willing Partner' Program"; and "Inland Shipbuilding for the Exacting Standards of the Rivers." Waterway Economics is designed for par- ticular use by academicians working in the fields of economics and transportation, and economists and research consultants working in businesses and foundations. Distribution of the monthly issues are limited to this group and to members of The American Waterways Operators, Inc. Numerous publishers, editors, and reporters for publications interested in water transpor- tation have expressed a desire for this material. It was not made available to such persons upon original publication because the Associa- tion did not desire to have it used for a gen- eral publication upon first issuance since doing so might have inhibited its use by teachers and researchers for whom it was originally designed. The pamphlet is the second reprint of Waterway Economics. The first contained eight issues comprising Volume I and was published in September 1968. Copies of Waterway Economics, Volumes II through IV may be obtained by writing The American Waterways Operators, Inc., 1250 Connecticut Avenue, Suite 502, Wash- ington, D.C. 20036. Single copies are free. / / , :; \ J • * V - 1 w^ Jis!'" ffp i' - h \ •,.: % * •F JJV SIMULATING SEA CONDITIONS: Simulating operating conditions on the high seas, a 2,000-kilowatt emergency power unit is tilted 15 degrees on a test rack at the La- Grange, III. plant of Electro-Motive Division of General Motors. The unit is one of four such emergency power units scheduled for installation aboard the U.S. Navy's newest nuclear aircraft carrier Nimitz. The unique test- ing facility permits tilting of the engine 15 degrees to either port or starboard, and five degrees fore and aft. Under such conditions, the unit must start and assume load in 10 seconds, and accept sudden large increments of load with little deviation in speed and voltage. The total test calls for 1,000 hours for endurance under varying power loadings. , • • j«HHH •Mr mm •¥ . : \ • ••••••• : S - • BBBHRBR (( HARCO FLUSH SCUTTLE »» • 18" Aluminum, light weight — high strength • Quick opening from inside & out e Easily installed • Cover gasket readily replaceable • All parts non-magnetic and isolated • Nearly 30 years of excellent service IDEAL FOR NAVY - COMMERCIAL - PLEASURE CRAFT MFG.
