But again Walker's hopes were disappointed. The most important of the monopolies, tobacco, had to be given up because the American product could not be excluded, and for administrative reasons the other monopolies also were surrendered. Owing to the dangers of waste, corruption, extortion and resentment, the business of collecting taxes had to be entrusted to the state authorities, and they possessed wonderful dexterity in the arts of evasion. State assessments were actually made on México and Vera Cruz only. The owners of occupied buildings were in many cases friends, and could not well be deprived of their rents. Contracts or agreements that stood in the way had to be respected. Gold and silver were clandestinely exported. Smuggling across the northern border could not be stopped. Brigands exacted their toll. The time required for investigation and planning, and in certain instances for correspondence with our government, militated against prompt action. We strongly desired to settle with Mexico and evacuate the country, and hence--especially after the peace negotiations began--it would not have been wise to run the risk of exasperating the nation for the sake of a few dollars. In short the net proceeds, including $106,928 turned in by naval officers, were only $3,935,676.[33.23] Some of this money went directly to supply needs of the army and navy, but by far the greater part of those needs had to be met in other ways. During the first nine months of 1847, it was figured that the United States exported more than $12,000,000 in specie to Mexico. Many drafts on the principal American cities were sold there, and those on the quartermasters at New Orleans, Philadelphia, Washington and New York amounted to nearly $8,000,000 before December, 1847. Payments were also made in the United States on the certificates of officers acting in the field; and about the first of August, 1847, Belmont, the New York agent of the Rothschilds, arranged with our administration to place funds in the hands of any paymaster or quartermaster named by Scott. In general the large financial operations made necessary by the transfers of money were skilfully, honestly and safely conducted. Some $24,000,000 were distributed by the pay department through its thirty-five officers, for instance, and nothing was lost by accident, robbery, theft or capture.[33.24] [THE COST OF THE WAR]
