the Crusade and terminated only by his death, made him frequently the recipient of magnificent presents. We read that on one occasion an eastern potentate sent him a dozen camels laden with silver and gold. All ships trading to Palestine were required to bring back a cross-bow for each of their cables, a measure which, while it replenished the royal arsenals with the most effective weapons of the age, was free from the dangers of official incapacity or corruption, and entailed no expense on the government. A great fleet of galleys, commanded by the Genoese admiral Spinola, maintained the naval power of the kingdom and protected the coasts from the depredations of pirates. In the internal administration of the kingdom, the most progressive and equitable ideas of commercial honor and common advantage prevailed. No duty could be levied on articles of necessity transported from one province to another. While monopolies were not forbidden, they were restricted to the crown, and the oppression resulting from this measure in other countries was not felt by the subjects of Frederick.

Constant war made these impositions onerous at times, but there was some relief in the knowledge that the clergy were forced to contribute their share to the public burdens, an inconvenience from which they were elsewhere exempt.

The breeds of horses, asses, and cattle were improved; the greatest care was taken of these animals. Food, which after experiment was found to be the most nutritious, was adopted; and the Emperor, whose interest in these matters was stimulated by the profit he derived from his stables, personally scrutinized their management with the most assiduous care. The supervision exercised by government officials over all occupations was most precise, and must have often proved vexatious. Weights and
