REPORT OF BOARD OF CONSULTING ENGINEERS, PANAMA CANAL.31


 The CHAIRMAN. You made these computations?
 Mr. BERTONCINI. I made those computations; yes, sir.
 The CHAIRMAN. What were the data from which you took your figures?
 Mr. BERTONCINI. I took them from the cross sections given by the new company.
 The CHAIRMAN. You did not take into account anything that has been done by the United States?
 Mr. BERTONCINI. These cross sections were made by the last French company when the work stopped. They made a project for the canal with 2, 4, or 6 locks, and they are the sections and profile showing the amount of material to be excavated. On these sections I made the calculations.
 The CHAIRMAN. The material the New French Canal Company has taken out since then is embraced in these quantities?
 Mr. BERTONCINI. It is shown; it is in dependent.
 The CHAIRMAN (reading): Work performed by the New Panama Canal Company 10,000,000, 1895-1904; 1881-1889, work performed by the old canal company 48,000,000;" that is a total of 58,000,000 cubic yards. The cross sections on which you made your computations are shown on the margin?
 Mr. BERTONCINI. Yes, sir.
 Mr. HUNTER. Is this calculated by taking a mean section?
 Mr. BERTONCINI. I t is taken by cross sections.
 Mr. HUNTER. Have you worked this out as an average cross section?
 Mr. BERTONCINI. I took it from the cross sections of the land.
 The CIAIRMAN. What does that represent, that picture there, is that Culebra?
 Mr. BERTONCINI. That upper ine means nothing. I have taken profiles from Culebra. I took the whole book of cross sections.
 The CHAIRMAN. Book of cross sections? Is it printed?
 Mr. BERTONCINI. Yes, sir.
 The CHAIRMAN. By whom?
 Mr. BERTONCINI. In Paris.
 The CHAIRMAN. Has that been among our papers, a book of cross sections? I have never seen it.
 Mr. BURR. I do not remember it.
 The CHAIRMAN. How many in all?
 Mr. BERTONCINI. I have a set in my office of the profiles from kilometer 0 to kilometer 74.
 Mr. BURR. What distances?
 Mr. BERTONCINI. I think they are every 20 meters (65.6 feet).
 Mr. BURR. Throughout the entire line?
 Mr. BERTONCINI. Yes, sir.
 The CHAIRMAN. There are 50 for each kilometer?
 Mr. BERTONCINI. Yes, sir; a book about that high [indicating].
 rfhe CHAIRMAN. I have never seen it.
 Mr. BERTONCINI. 1 have it in my office at Panama.
 The CHAIRMAN. Fifty cross sections for each kilometer?
 Mr. BERTONCINI. Yes, sir. All that was surveyed by the New Panama Canal Company; the whole canal.
 The CHAIRMAN. What did it show in respect to deviations, what they call derivations?
 Mr. BERTONCINI. Very little difference. Some fillings here and there on the Atlantic side.
 The CHAIRMAN. The sections were taken clear across everything?
 Mr. BERTONCINI. Yes, sir.
 The CHAIRMAN. Do your cross sections treat of anything except the main line of the canal, or do they include the main route of the canal and the derivations also?
 Mr. BERTONCINI. They include in some cases the derivations, but generally that is a work apart.
