Show tests being made), it was found that 30,024,000 cubic yards passed through Hanlon gate. Reducing the cubic yards to tons, we find that 40,532,580 tons of silt, equivalent to 1,351,086 carloads of thirty tons each, was carried through Hanlon Heading in this one year. These figures were furnished by Chief Engineer J. C. Allison at the request of your receiver, and are conservative and based upon a careful investigation. Assuming that 1914 was a fair illustration of the quantity of silt carried, there has been discharged through Hanlon gate in seven years' time, as much saturated silt as has been excavated from the Panama Canal. Of this silt the dredger fleet removed during the year 1914, 1,510,775 cubic yards, at a total cost to your receiver of $187,175.78, being a little in excess of 12^ cents per cubic yard. The facts concerning the silt problem, as herein shown, are given that the great cost of operating the canal system might be more clearly understood by Your Honorable Court. The dredger fleet that is now a part of the California Development Company's properties, acquired under the direction of your receiver comprises two floating suction dredgers at the Colorado River intake, three floating dipper dredgers for use on the west side main and the canals in Mexico, and three Stockton dredgers, particularly adapted and almost constantly used in the main laterals of Imperial Valley. The dredgers at the Colorado River were the first built by your receiver and have wooden hulls. The three dipper dredgers, built during the years 1914 and 1915, are of a later and better model, the hulls being of steel. |
