You arc aware that l have no theodolite at my dispo sa ~ tbe triangulation must, therefore, be m«de with the sextant. The population, number of cattle, horses, and sheep, and the quantity of grain and other agrin;~1tural products, th' faeilities and best localities for wat r power to propel mach in ery, an1l also the mineral rec;ourccs of the country, it is v'ry dc, irab'le to know. You will, therefor, give particular attention to tt·quiring all the information on these suhjerls whi ·h the pr sent stati tical l nowledge in the country will afford. A requisition for five thousand dollars will be made on the Bureau of Topographical Engineers for the survey, to be plac d to your cre(li t with Mr. llo bert Camp bell of St. Louis, tJ pon whom, I shou ltl think, you might safely (lraw, without waiting to hear from Washington. I made a requisition on the bureau, dated June 18, 1846, for a 1.ran it instrument, and also for an instrument to obtain the mag netic dip and declination. Shoul1l these arrive, you will unpack them, mount the instruments ncar the pla ·e where I ob. erve1l in Santa E'6, and commence a series of ob ervations for longitude by moon culminating stars, and for the magnetic dip and declination. The series for longitude will be continued for at least three lunalions, and, should an opportunity pre ent itself, I wish the observations and results to be communicate<l to me in California. I am, very respectfully, your obedient servant, W. Il. ENTORY, Fi1·3t Lieut. CoTps Top. Engineers. Lieutenant J. vV. AnERT, or, in his absence, Lieu tenant 'V. G. PEcic • Ex. Doc.
