At the end of May, 1847, he returned to the east, and Colonel R. B. Mason of the First Dragoons, whom the government had sent out for the purpose, became governor and commander-in-chief. Mason was an excellent executive, able, experienced, sensible, strong and faithful. Some thought his character hard, but probably all clear-headed persons realized that it was just. He believed in firm though kind methods, avoided entanglements, and bore sway successfully till the close of the war.[31.21] The restless faction of the Los Angeles district, free from the restraint of a large American element, still existed, and at intervals caused considerable anxiety. Indeed it is clear from Mexican sources that a hope of troops from the south was fondly cherished there for a long time. The approach of the Mormon battalion, which--after suffering many hardships on the route from Santa Fe--arrived at San Diego under Captain Cooke in January, 1847, excited the people, for that sect was loathed in California. A great deal of trouble about land titles arose, for the surveying had been poorly done, the boundaries overlapped in many instances, and few had the proper documents. Frémont's volunteers, expecting large pay, refused to be mustered into the service under the law of May 13, 1846, and were discharged in a very angry frame of mind, April, 1847, with no pay at all; and very little was done toward compensating the people for the spoliations committed by the volunteers.[31.21] The government, though tempered by the maintenance of the alcalde system, was necessarily a military one; the old alcaldes, familiar with the customs of the land, would not serve; the new ones, though generally good men, could not always give satisfaction; and the growing American element, disgusted with so unsystematic a system, demanded self-government and written laws. No funds could legally be had for the expenses of war and civil administration except those derived from the customhouses, and the Americans were so deeply committed by their promise of low duties that Mason felt compelled to reduce the tariff explicitly ordered by the government. There were jealous differences of opinion on many points between the Californians and the Americans, between the various nationalities of the foreigners, and between the old and the new immigrants; and finally the people were disturbed by serious quarrels between the Stockton-Frémont party and the Kearny-Mason party, and by the old fear that eventually the Americans would sail away, leaving them to settle with Mexico as best they could.[31.21]
