CHAPTER VII. 



SAN FRANCISCO TO MANILLA. 

 1841. 



By the 28th of October, all the exploring parties had returned, and 

 the duties of the observatory and surveys were completed. The 

 instruments were at once embarked, and preparations made to sail 

 with the first fair wind. 



By a series of observations of moon culminating stars, the longitude 

 of Sausalito Fort was found to be 122° 25' 36" W. ; the latitude, by 

 numerous altitudes, 37° 50' 50" N. Full series of magnetic observa- 

 tions were also made, with the usual meteorological record. The 

 mean temperature for the eighty days during which the Vincennes 

 lay at Sausalito was 61-6°. 



The addition of the brig Oregon to the squadron rendered many 

 changes necessary in the distribution of the officers. The command 

 of that vessel was given to Lieutenant Carr, first lieutenant of the 

 Vincennes, and such officers were ordered to act under him as would 

 insure efficiency and harmony in the duties that remained to be 

 completed. 



It was with no little regret that I parted with Lieutenant Carr, 

 who had been the executive officer of my ship for upwards of two 

 years, during which time his duties had been at all times responsible, 

 arduous, and valuable to the Expedition. By his excellent manage- 

 ment the vessel had been kept in the best possible order, and while 

 the comforts of the men were carefully attended to, the rules and 

 regulations of the vessel were strictly enforced. In addition to the 

 sufficiently arduous duties of executive officer, he was, during my 

 frequent and necessary absences, charged not only with the duties on
