Fifteenth conclusion: The number of ministers required for each community cannot be readily determined, since there are not in all the encomiendas the same conditions existing; in some, the people live closer together than in others; and where they are more scattered, or more difficult of access, more ministers will be needed than when they live nearer one another. When they are thus near, and well disposed, five hundred Indians are a sufficient number for one conscientious minister to take in charge; and when we shall have an abundant number of ministers, they should be stationed in each encomienda, in that ratio. Sixteenth conclusion: If through lack of ministers enough cannot be placed in each encomienda to give adequate instruction, such as can be obtained at the time should be employed, and the encomenderos shall remain under obligation to deduct from the tributes what has been stated in the seventh conclusion. Seventeenth conclusion: All that the Indians have expended in erecting churches and houses for the ministers, and in their maintenance, through the unwillingness of the encomenderos to pay therefor, the latter are obliged to make good--the entire amount expended, for the maintenance of the ministers; and of that expended for churches and houses, their share. Eighteenth conclusion: In order that, from this time forth, the encomenderos who do not maintain religious instruction may collect from their encomiendas the portion which is stated in the second conclusion, the following conditions shall be observed: (1) They shall endeavor, most assiduously and earnestly, to establish religious instruction in their encomiendas, that such establishment shall not be delayed; or, if it be not made, so that the lack cannot be imputed to their negligence and indifference. And, inasmuch as we have not here the requisite number of ministers, the encomenderos shall inform his Majesty how great is the lack, and supplicate him promptly to send ministers hither--offering, if it shall be necessary, to pay a part of the expenses to be incurred in sending them hither. (2) The encomenderos shall endeavor, personally or through the medium of persons skilled and competent, in whom may be placed entire confidence that they will deal with the Indians as God requires and the king commands, to defend the Indians and protect them against the injuries inflicted upon them. They shall strive to influence them, by good works and example, to accept the law of God, most carefully preparing them so that, when they have ministers of the Christian doctrine, they can be instructed. They shall not act as do some encomenderos (and most of them are of this sort) who visit their encomiendas not for the good of the Indians, but for their own profit; and who, through their presence, work more injury to the Indians by the many grievances which they occasion, and the bad example that they set, than the latter are advantaged in being thus pacified.
