The revenues of the Empire consisted of a tax on every sixty measures of corn; of a house-tax, or tax on every fire; the customhouse (p. 127) dues, and what remained of the municipal taxes after paying expenses; of a tax on public baths; the farming out of lands belonging to the crown; the fines and confiscations in the "Court of the Brigands;" and finally of the tribute paid by thirty-six towns and their landed possessions "belonging to the Crown." The Courts of Justice belonged to the Middle Ages; tortures were applied similar to those employed by the Spanish Inquisition. A wife who murdered her husband "was buried alive up to her neck." Heretics were burned at the stake; sorcerers were burned in an iron cage, and coiners had liquid metal poured down their throats. A noble who killed a moujik was fined or sometimes whipped; but he might kill as many slaves as he pleased, because they were his property. The Russian infantry, so famous under the early Norsemen, had given way to cavalry, in imitation of the Tartars. The Imperial Guard was composed of 8,000 young nobles. The "men-at-arms" were mounted, but received no pay beyond the revenue of their lands, which they held in return for their military service. The army numbered about 80,000, and, with a levy among the peasants, could be brought up to 300,000. There was, besides, the irregular cavalry of the Don Cossacks, and of the Tartars. Such infantry as there was, consisted of peasants from the crown lands, churches, and convents; the national guard, and foreign soldiers or officers. [Illustration: Feodor] (p. 128) XV--FEODOR, THE LAST OF RURIK'S DESCENDANTS. (p. 129) Ivan the Terrible left two sons, Feodor, the son of Anastasia Romanof, and Dmitri, a child, the son of his seventh wife. Feodor was neither a strong-minded nor a very able man. He was married to Irene Godounof, and, following the usual custom, his wife's relations held the principal offices of the government. Gradually the czar's authority passed into the hands of Prince Boris Godounof, Irene's brother, a very ambitious and unscrupulous man. Wizards had foretold that Boris would be czar, but that his reign would last only seven years, and he did all he could to aid his destiny.
