The most important head of receipt was the excise, which, in the last year of the reign of Charles, produced five hundred and eighty-five thousand pounds, clear of all deductions. The net proceeds of the customs amounted in the same year to five hundred and thirty thousand pounds. These burdens did not lie very heavy on the nation. The tax on chimneys, though less productive, call forth far louder murmurs. The discontent excited by direct imposts is, indeed, almost always out of proportion to the quantity of money which they bring into the Exchequer; and the tax on chimneys was, even among direct imposts, peculiarly odious: for it could be levied only by means of domiciliary visits; and of such visits the English have always been impatient to a degree which the people of other countries can but faintly conceive. The poorer householders were frequently unable to pay their hearth money to the day. When this happened, their furniture was distrained without mercy: for the tax was farmed; and a farmer of taxes is, of all creditors, proverbially the most rapacious. The collectors were loudly accused of performing their unpopular duty with harshness and insolence. It was said that, as soon as they appeared at the threshold of a cottage, the children began to wail, and the old women ran to hide their earthenware. Nay, the single bed of a poor family had sometimes been carried away and sold. The net annual receipt from this tax was two hundred thousand pounds. [40] When to the three great sources of income which have been mentioned we add the royal domains, then far more extensive than at present, the first fruits and tenths, which had not yet been surrendered to the Church, the Duchies of Cornwall and Lancaster, the forfeitures, and the fines, we shall find that the whole annual revenue of the crown may be fairly estimated at about fourteen hundred thousand pounds. Of this revenue part was hereditary; the rest had been granted to Charles for life; and he was at liberty to lay out the whole exactly as he thought fit. Whatever he could save by retrenching from the expenditure of the public departments was an addition to his privy purse. Of the Post Office more will hereafter be said. The profits of that establishment had been appropriated by Parliament to the Duke of York.
