Naval Service and in the Government, and, as a matter of fact, it is my justifiable ambition as district public works officer to build the base wherever it

may

be located. I am already on record with the department as desiring above all things a naval base on the Pacific in the shortest possible time and to the effect that, while I see no reason to change my opinions as submitted in my report of July, 1919, I would be only too glad to concur in any final decision which may be rendered by competent authority in order to get the base. With the shifting of the probable theater of war from the Atlantıc to the Pacific, it must be apparent, first, that we want such a base badly; and, second, that we want it in the shortest possible time. I might add, from the standpoint of the taxpayer, that we want it at the least' possible expense. None of these considerations would justify the selection of an unsuitable site from a military standpoint, but, granted that military requirements are satisfied by the site Í propose, as I sincerely believe them to be, I would surely be derelict in my duty as an officer and a public servant were I to fail to point out the very appreciable saving to the Government in time and in money attainable by the adoption of the Carquinez Straits site for the proposed naval base of the Pacific.

I have in this statement attempted to outline briefly and in a very general manner the project I propose. I am now prepared to answer to the best of my ability any questions you may wish to put to me and to go into all engineering and cost features with such detail as you may deem advisable. As you are doubtless aware, I have had at my disposal neither the funds nor the authority for the preparation of design drawings or the inauguration of actual construction estimates, of quantities or costs, but I believe I am able to give you such preliminary data as may be reasonably expected at this stage of your work,
