generally levied at harvest-time, was furnished by the common lands, and stored in magazines in the principal cities. Maize and other grain was contributed in large chests (Fig. 18, _l_), and cotton (_r_), cacao (_a_) and pepper in bales. Of manufactured articles, textiles (_s_) and ceremonial costumes (_m_) were the most common, but the tribute-lists show a great variety. Many of the town-names in these lists cannot now be located, but their geographical position can be roughly assumed from the nature of their contributions. From Soconusco came lip-plugs, cacao, feathers and hides, from Oaxaca province, gold and cochineal (Fig. 18, _h_), from the Tlalhuica, paper and pottery. Other forms of tribute were honey (_q_), lime, wood, salt (_g_), copal (_o_), sea-shells (_e_), amber (_f_), rubber, live eagles, copper axes, chalchiuitl beads (_c_), turquoise (_d_), swords, shields (_p_), and canes filled with perfumes for smoking. Tax-gatherers were received with great ceremony and respect, and the arrival of these officers at the town of Quiauiztlan, in Vera Cruz, is described by Diaz. A special apartment decked with flowers was prepared for them, together with food and chocolate; they arrived dressed in richly embroidered cloaks and loin-cloths, their hair bound up on their heads, each carrying a crooked staff and a bouquet of flowers which he smelled from time to time. The Totonac it is true complained to the Spaniards of the harshness of Mexican rule, probably referring rather to the Aztec demands for sacrificial victims. Tribute on the whole seems to have been fairly assessed, and was remitted in years of famine. While the first step in the evolution of the Mexican constitution is marked by the election of Acamapitzin as king, in place of the old tribal council under a president, yet it was the overthrow of Azcapotzalco which gave the hegemony of the valley to Mexico, and compelled it to provide for the administration of dependent cities. A number of officials bearing titles similar to those at home were sent to Coyoacan, and definite arrangements were made with the allied states of Texcoco and Tlacopan in accordance with which the rulers of these cities became, at least nominally, electors of the Mexican kings, and placed the direction of their military policy in the hands of the latter. It was only in military matters that the two confederate states deferred to Mexico; they had their own sovereigns, their own laws and provinces, and we are told that Tezcoco exercised dominion over no less than fifteen of the last-named in the direction of the Atlantic coast. Each ruler confirmed the election of their sub-chiefs, and they of their dependents. Of the booty won by the united armies, two-fifths was taken by Mexico, two-fifths by Tezcoco, and one-fifth by the small state of Tlacopan.
