Altogether the items were almost as numerous as in a modern budget, but one chief source of present revenue, the customs duties, is conspicuously absent, and the general aspect of the system is far more that of income from property than in a modern state, even fines and fees having a personal rather than a political character. A careful estimate of all the revenue accounted for in this Pipe Roll of 1130 shows that Henry's annual income probably fell a little short of 30,000 English pounds in the money of that day, which should be equal in purchasing power, in money of our time, to a million and a half or two million pounds.[26] This was a large revenue for the age. Henry knew the value of money for the ends he wished to accomplish, and though he accumulated large store of it, he spent it unsparingly when the proper time came. England groaned constantly under the heavy burden of his taxes, and the Pipe Roll shows us that there was ground for these complaints. The Danegeld, the direct land-tax, had been taken for some years before this date, with the regularity of a modern tax, and as it was taken at a rate which would make it in any age a heavy burden, we can well believe that it was found hard to bear in a time when the returns of agriculture were more uncertain than now, and when the frequently occurring bad seasons were a more serious calamity. Economically, however, England was well-to-do. She had enjoyed during Henry's reign a long age of comparative quiet. For nearly a generation and a half, as the lives of men then averaged, there had been no war, public or private, to lay waste any part of the land. In fact, since early in the reign of Henry's father, England had been almost without experience of the barbarous devastation that went with war in feudal days. Excessive taxation and licensed oppression had seemed at times a serious burden. Bad harvests and the hunger and disease against which the medieval man could not protect himself had checked the growth of wealth and population. Yet on the whole the nation had gained greatly in three generations.
