DOCUMENTARY HISTORY OF THE FLORIDA CANAL mentioned, that was made by the Department of Commerce at the request of the Chief of Engineers, and which has been published in five volumes. Senator VANDENBEao. And which I have painfully read. Mr. BucKrxN. And a third and independent economic survey made by the examining engineers of the Public Works Administration. Those are public records. Senator VANDENBERO. All right. That is the basis Mr. BUCxMAN. Those are the bases. Senator VANDENBERG. All right. And you are going to discuss this Department of Commerce report later, as I understand it? Mr. BucKMAN. No; I am not going to discuss it at all. I think I told you that I was going to mention it; that is all. Senator VANDDENBEG. Oh. Senator FLizTCHE. This report of the special board gives the ship, the name of the ship, and the entire cargo, and all the details. Mr. BucKMAN. The original survey picks out each ship by name and its record and the cargoes carried. Senator VANmENBao. There is not any question but what that is so, and then they assume they are going to use the canal, and then arrive at the subsequent figures Mr. BUCXMAN. May I point out to you, Senator, the Corps of Engi- neers uses the same method in determining the use of any waterway by commerce. They have always done it in the past and presumably will do it in the future. Senator VANDENrEG. I am terribly sorry to disagree with you, but I was never interested in a Great Lakes project that I was not required to produce witnesses in presenting the actual which was in existence or in dependable contemplation. Mr. BUCKMAN. That is auxiliary testimony that it is well to have, and which the Army engineers bring to bear, but as I shall read to you in a moment from a statement of the Chief of Engineers, that is not the chief basis for their economic justification, or their conclusions regarding the economics of the canal; if you will bear with me one moment, I will come to that. Senator VANDENBERG. All right. Senator FIzTCHE. I was going to ask, Mr. Chairman, if you re- member the tolls of the Panama Canal. I forget what they do charge down there. The CHwamiRA. $1 a ton. Senator FLPTcaHR. $1 a ton. So this 8 cents a ton is a pretty low estimate. Mr. BUCKMAN. On August 30, 1935, by virtue of authority vested in him under the Emergency Relief Appropriation Act of 1935, ap- proved April 8, 1935, the President authorized the project and directed the Secretary of the Treasury to transfer to the War Depart- ment, Corps of Engineers, $5,000,000 of the funds provided in that act for the initiation of work. On September 3, 1935, construction was begun under the direction of the Chief of Engineers, and is continuing at this time, with an average employment of approximately 5,000 men. 237
