Seite 17 - Such canal shall be of sufficient capacity and depth as shall afford convenient passage for vessels of the largest tonnage and greatest draft now in use, and such as may be reasonably anticipated, and shall be supplied with all necessary locks and other appliances to meet the necessities of vessels passing through the same from ocean to ocean; and he shall also...
Seite 133 - The great objection to the locks at Sosa Hill is the possibility of their destruction by the fire from an enemy's ships. If, as has been suggested to me by officers of this Department entitled to speak with authority on military subjects, these locks may be located against and behind Sosa Hill in such a way as to use the hill as a protection against such fire, then economy would lead to the retention of this lake. The lake would be useful to commerce as a means for relieving any possible congestion...
Seite 25 - The sum of my conclusions is, that, all things considered, the lock or high-level canal is preferable to the sealevel type, so called, for the following reasons: "It will provide as safe and a quicker passage for ships, and, therefore, will be of greater capacity. "It will provide, beyond question, the best solution of the vital problem of how safely to care for the flood waters of the Chagres and other streams. "Provision is made for enlarging its capacity to almost any extent at very much less...

Seite 25 - The time and cost of its construction will be not more than one-half that of a canal of the sea-level type. The element of time might become, in case of war, actual or threatened, one of such importance that measured, not by years but by months, or even days, the entire cost of the canal would seem trivial in comparison. Finally, even at the same cost in time and money for each type, I would favor the adoption of the high-level lock canal plan in preference to that of the proposed sea- level canal.
Seite 25 - Provision is made for enlarging its capacity to almost any extent at very much less expense of time and money than can be provided for by any sea-level plan. Its cost of operation, maintenance, and fixed charges will be very much less than any sea-level canal. The time and cost of its construction will not be more than one-half that of a canal of the sealevel type.
Seite 151 - ... material 200 feet thick. The borings on the high ground, at the site of the locks, the regulating works, and elsewhere, showed generally soft clay to a depth of 20 to 30 feet below the surface, where indurated clay — a soft but compact rock — was found. In making the design of an earth dam at Gatun, it was thought best to provide a dam which could not be destroyed by any of the forces of nature, and which could only be destroyed by making excavations which would require a large force working...

To lay down one's life upon the field of battle in voluntary service of fatherland has been considered in all ages the loftiest expression of patriotism, if not of heroism itself. To fall as Gaillard...
