These were the most constant and regular branches of the revenue. But there were other ways innumerable by which money, or an equivalent in cattle, poultry, horses, hawks, and dogs, accrued to the exchequer. The king's interposition in marriages, even where there was no pretence from tenure, was frequently bought, as well as in other negotiations of less moment, for composing of quarrels, and the like; and, indeed, some appear on the records, of so strange and even ludicrous a nature, that it would not be excusable to mention them, if they did not help to show from how many minute sources this revenue was fed, and how the king's power descended to the most inconsiderable actions of private life.[73] It is not easy to penetrate into the true meaning of all these particulars, but they equally suffice to show the character of government in those times. A prince furnished with so many means of distressing enemies and gratifying friends, and possessed of so ample a revenue entirely independent of the affections of his subjects, must have been very absolute in substance and effect, whatever might have been the external forms of government. For the regulation of all these revenues, and for determining all questions which concerned them, a court was appointed, upon the model of a court of the same nature, said to be of ancient use in Normandy, and called the Exchequer. There was nothing in the government of William conceived in a greater manner, or more to be commended, than the general survey he took of his conquest. An inquisition was made throughout the kingdom concerning the quantity of land which was contained in each county,--the name of the deprived and the present proprietor,--the stock of slaves, and cattle of every kind, which it contained. All these were registered in a book, each article beginning with the king's property, and proceeding downward, according to the rank of the proprietors, in an excellent order, by which might be known at one glance the true state of the royal revenues, the wealth, consequence, and natural connections of every person in the kingdom,--in order to ascertain the taxes that might be imposed, and, to serve purposes in the state as well as in civil causes, to be general and uncontrollable evidence of property. This book is called Domesday or the Judgment Book, and still remains a grand monument of the wisdom of the Conqueror,--a work in all respects useful and worthy of a better age. The Conqueror knew very well how much discontent must have arisen from the great revolutions which his conquest produced in all men's property, and in the general tenor of the government. He, therefore, as much as possible to guard against every sudden attempt, forbade any light or fire to continue in any house after a certain bell, called curfew, had sounded. This bell rung at about eight in the evening. There was policy in this; and it served to prevent the numberless disorders which arose from the late civil commotions.
