Very frequently the cost of the dam brought from the bottom to the level of the river bed is equal to the cost of it from there up to the top. Mr. Hayden. And it was very fortunate, was it not, that it was possible to find such a shallow depth to bedrock for the dam? Mr. Reed. It was very fortunate. The studies of the Indian Service are printed in the hearings of the former congressional investigating committee, known as hearings before the Committee on Indian Affairs, on the condition of various tribes of Indians. Mr. Hayden. That was four years ago. Mr. Reed. Yes, sir. That is published so far as the descriptive matter in the table is concerned, but the appendices which lead up to all the opinion and conclusion were never published, but are available if desired. The Chairman. I thought nearly everything was in that report. Mr. Reed. There were maps and tables and water measurements, and, I believe, twice as much as was published. The Army board report in 1914 has been published--Sixty-second Congress, second session, Document No. 791. That contains a vast amount of information, and from all of these the chart computations that I am presenting here have been made. The $5,500,000 project which is referred to here really is simply for the dam and the necessary work in connection therewith. The Chairman. It does not contemplate the purchase of any land that may have to be purchased or contain the supply space for the reservoir? Mr. Reed. Yes; the reservoir is all on an Indian reservation--San Carlos Reservation. The Chairman. So there is no expense in purchasing of land? Mr. Reed. There will be some expense in the purchase or in the payment for condemning buildings and some small works of that kind. The estimate made by the representatives of the Indian Service was practically $200,000, and the Army engineers, after investigating, concurred. Mr. Hayden. That $200,000 is included within the limit of $5,500,000? Mr. Reed. Yes. The Chairman. It does not contemplate any ditches or any development of the irrigation scheme except the dam, does it? Mr. Reed. Except the dam and reservoir. The Chairman. Impounding the water? Mr. Reed. Yes. The distribution system will consist of diversion dams lower down, one of which, as you know, is already constructed. The other one is now under construction with appropriations sufficient to finish it. That includes a bridge as well as the dam. The canal is also under construction, and $400,000 has been appropriated outside of the appropriation for this year, which I understand is in the neighborhood of $200,000. Mr. Hayden. How much will be needed to complete that main canal? Mr. Reed. The estimate for the comupletion of the Florence-Casa Grande canal and Pima lateral is $733,652
