by the continual supply of Christian slaves, at first captives of tender age taken in war, and afterwards, when this source proved inadequate to the increased demand, by an annual levy among the children of the lower orders of Christians throughout the empire--a dreadful tax, frequently alluded to by Busbequius, and which did not finally cease till the reign of Mohammed IV. At a later period, when the Krim Tartars became vassals of the Porte, the yearly inroads of the fierce cavalry of that nation into the southern provinces of Russia, were principally instrumental in replenishing this nursery of soldiers; and Fletcher, who was ambassador from Queen Elizabeth to Ivan the Terrible, describes, in his quaint language, the method pursued in these depredations: "The chief bootie the Tartars seeke for in all their warres, is to get store of captives, specially young boyes and girles, whom they sell to the Turkes, or other, their neighbours. To this purpose, they take with them great baskets, made like bakers' panniers, _to carrie them tenderly_; and if any of them happens to tyre, or bee sicke on the way, they dash him against the ground, or some tree, and so leave him dead." (_Purchas's Pilgrims_, vol. iii. p. 441.) The boys, thus procured from various quarters, were assembled at Constantinople, where, after a general inspection, those whose personal advantages or indications of superior talent distinguished them from the crowd, were set aside as pages of the seraglio or Mamelukes in the households of the pashas and other officers, whence in due time they were promoted to military commands or other appointments: but the remaining multitude were given severally in charge to peasants or artisans of Turkish race, principally in Anatolia, by whom they were trained up, till they approached the age of manhood, in the tenets of the Moslem faith, and inured to all the privations and toils of a hardy and laborious life. After this severe probation, they were again transferred to the capital, and enrolled in the different _odas_ or regiments; and here their military education commenced.--H.

[160] _Ethnology_, etc., p. 439: "The Hungarian nobility ... is proved by historical and philological evidence to have been a branch of the great Northern Asiatic stock, closely allied in blood to the stupid and feeble Ostiaks, and the untamable Laplander."
