Secretary of the Interior.

DEAR MR. SECRETARY : In compliance with the instructions of the late President Kennedy, as expressed at the White House meeting of July 16, 1963, and in accord with our agreement, I am pleased to transmit herewith iny report on the cost and engineering aspects of supplemental studies pertaining to the international Passa maquoddy tidal power project and upper St. John River hydroelectric power development. Sincerely yours,

W. K. Wilsox, Jr.,
Lieutenant General, l'.S. Army.

Chief of Engineers.

U.S. ARMY ENGINEER DIVISION, NEW ENGLAND,

CORPS OF ENGINEERS,

Waltham, Mass., April 10, 1964. Subject: Transmittal of supplementary engineering report to the Secretary of

the Interior's report entitled "The International Passamaquoddy Tidal Power

Project and Upper St. John River Hydroelectric Development." To: Chief of Engineers. Attention: ENGCW-E, Washington, D.C.

1. Pursuant to instructions outlined in your letter of July 23, 1963, and in accord with your agreement with the Secretary of the Interior, a supplementary engineering investigation has been undertaken in support of the Secretary of the Interior's report of July 1963 to the late President Kennedy. The investigation covers engineering layouts and cost estimates for various sizes of powerplants with ultimate installed capacity of 1 million kilowatts at Passamaquoddy, Eastport, Maine; and hydroelectric development at Dickey, Maine, on the upper St. John River with ultimate installed capacity of 760,000 kilowatts and a reregulating dam and powerplant with 34,000 kilowatts installed capacity 11 miles downstream at Lincoln School, Maine. The investigation and report were accomplished with the advice and guidance of the Army-Interior Advisory Board on Passamaquoddy and upper St. John River.

2. The supplementary engineering investigation is complete and the report is transmitted herewith.

P. C. HYZER,
Brigadier General, U.S. Army,

Division Engineer. 44
