And if, on the whole and in general, Joseph was reckoned a wise and equitable ruler, and even adored as a kind of saviour of the world, it would be idle in us to canvass the wisdom of his administration. When we have not sufficient historical material to apprehend the full significance of any policy, it is safe to accept the judgment of men who not only knew the facts, but were themselves so deeply involved in them that they would certainly have felt and expressed discontent had there been ground for doing so. The policy of Joseph was simply to economize during the seven years of abundance to such an extent that provision might be made against the seven years of famine. He calculated that one-fifth of the produce of years so extraordinarily plenteous would serve for the seven scarce years. This fifth he seems to have bought in the king's name from the people, buying it, no doubt, at the cheap rates of abundant years. When the years of famine came, the people were referred to Joseph; and, till their money was gone, he sold corn to them, probably not at famine prices. Next he acquired their cattle, and finally, in exchange for food, they yielded to him both their lands and their persons. So that the result of the whole was, that the people who would otherwise have perished were preserved, and in return for this preservation they paid a tax or rent on their farm-lands to the amount of one-fifth of their produce. The people ceased to be proprietors of their own farms, but they were not slaves with no interest in the soil, but tenants sitting at easy rents--a fair enough exchange for being preserved in life. This kind of taxation is eminently fair in principle, securing, as it does, that the wealth of the king and government shall vary with the prosperity of the whole land. The chief difficulty that has always been experienced in working it, has arisen from the necessity of leaving a good deal of discretionary power in the hands of the collectors, who have generally been found not slow to abuse this power.
