It may not be amiss to here remark incidentaliy that the nearest s-ttlement to the proposed new seat of government was Benicia, situated on the Straits of Carquinez, about eight miles distant. General Vallejo's dreams were of course never realized. The capital was but proved only a miserable affuir, the whole scheme terminated as a dre: Following is the repor: turned in by the committee “To the Honorab: ate and Assembly of the State of California: The undersigned Commiss'oners appointed by your respec- tive bodies to meet the two named by General M. G. Vallejo, for the purpose of selecting the several plats of ground pro- posed to be donated by bim to 1he State as set forth in his memorial, baving per- formed that duty, beg leave respectiully to repor: : “That in pursuance to your resoiutfon assigning said duty to them, they repaired to the city of Vallejo, and aiter diligent examination for severzl days, they unani- mously made selection of 1he several publc grounds for State purp rses. “The undersigned deemed it best to piace the Capitol, the Governor's house, together with the universiiy and several other institutions, on the elevated hill immediately upon the secure and com- modious harbor of Napa Bay, and from which point the whole of Sonoma and San Pably bays, from the Twin Sistersinto the Straits of Carquinez, may be seen; and from Capitol Hill, of a clear day, may be seen the City and shipping ot San Francisco, distance about twenty miles. “From this point also may be seen, to and moved, | | bnilding materials, and one of the best | | valleys of | west and on the south are the pictureque shores of | immediately in front, while Jontra Costa, the valley of San Pablo and the v is the range of Suscol Mountains, from which flows an abundance of good water, which is diseharged into Napa Bay. “As 2 commanding vosition, with fine harbor< in the world, with a neighbor- hood of unsurpassed fertility, your Com-+ missioners teiieve that 2 vetter location couid not be made.” The sub-tropical stalements embraced in the foregoing paragraphs disclose a fer- tility of description somewhat in advance of that period. The ‘‘distance” mentioned to San Francisco is of little importance, Twelve or filteen miles, more or less, dian’t amount to much in those good old days. Modern military engineering, how- ever, has produced long-tange. guns whoich throw projectiles that far, but we have no record yet of any telescope that conducts human vision along the line of the arc formed by the flizht of a ball while traversing that distance. In order to see shipping in the barbor of San Francisco from Vallejo *‘of a clear day” the eye wouid, unlortunately, have to penetrate the intervening mountams of Contra Costa on thesoutheast. However, Jules Verne anticipated equal achieve- ments in sclence in some of his early writings. The report continues: *“To the northward of Capitol Hill is one still more elevated, with all the command- ing advantages of the former, and wkich your Commissioners have selected as the site for the university. Your Commis- sioners would remark that it has been a k of Mount Diablo, and in the rear | cluded would not be best for the education | experience teaches the contrary; that ob- collegiate course would gain moré infor- | mation from the legislative debates than from the ablest professorship.” The wording of the ubove paragraph is characteristic of the times, and liberal, but s trifle bewildering. Itseems to oui- small space interv-ning, or it locates one university in two different places. Their earnest solicitude concerning the great advantages to be conferrad uvon students ti rouch the valuable medium of listening ‘to legislative debates is very praiseworthy; yet, with becoming | modesty, they wholly abs:ain from re- ferring to the higher and greater fund of information to be obtained from reading legislative reports.
