To meet this expenditure he painfully enumerated the funds upon which he could reckon for the two years. His ordinary rents and taxes being all deeply pledged, he could only calculate from that source upon two hundred thousand ducats. The Indian revenue, so called, was nearly spent; still it might yield him four hundred and twenty thousand ducats. The quicksilver mines would produce something, but so little as hardly to require mentioning. As to the other mines, they were equally unworthy of notice, being so very uncertain, and not doing as well as they were wont. The licences accorded by the crown to carry slaves to America were put down at fifty thousand ducats for the two years. The product of the "crozada" and "cuarta," or money paid to him in small sums by individuals, with the permission of his Holiness, for the liberty of abstaining from the Church fasts, was estimated at five hundred thousand ducats. These and a few more meagre items only sufficed to stretch his income to a total of one million three hundred and thirty thousand far the two years, against an expenditure calculated at near eleven millions. "Thus, there are nine millions, less three thousand ducats, deficient," he concluded ruefully (and making a mistake in his figures in his own favor of six hundred and sixty-three thousand besides), "which I may look for in the sky, or try to raise by inventions already exhausted." Thus, the man who owned all America and half of Europe could only raise a million ducats a year from his estates. The possessor of all Peru and Mexico could reckon on "nothing worth mentioning" from his mines, and derived a precarious income mainly from permissions granted his subjects to carry on the slave-trade and to eat meat on Fridays. This was certainly a gloomy condition of affairs for a monarch on the threshold of a war which was to outlast his own life and that of his children; a war in which the mere army expenses were to be half a million florins monthly, in which about seventy per cent. of the annual disbursements was to be regularly embezzled or appropriated by the hands through which it passed, and in which for every four men on paper, enrolled and paid for, only one, according to the average, was brought into the field.
