50. I have also been informed that, in collecting the tributes from the Indians, there has been in the past, and is at present, great disorder, because the former governors of the said islands have done things very confusedly and haphazardly. Because the tribute of each Indian is of the value of eight reals, paid in what the Indian might possess, some persons take advantage of certain words of the said assessments, and of the articles in which tributes are designated--such as cotton cloth, rice, and other products of the country--to cause the said lawlessness. This disorder has consisted in each one collecting whatever he wished, to the great offense and injury of the said Indians; for when gold is abundant, their encomenderos demand coin from the Indians; and when coin is abundant and gold scarce, they demand gold, although the said Indians have to search for and buy it. In short, they always demand their tributes in those things which are scarce, by reason of which, for the tribute worth eight reals, some collect fifteen, and others twenty, twenty-five, thirty, and more, according to the value of those things that are demanded. They cause the Indians to seek them and bring them from other parts, to their great vexation and affliction. It is advisable to check this lawlessness and excess. Therefore I charge you to ordain that, in the payment of the said tributes, the order referred to in section six of these instructions shall be observed. That section treats of the Indians being allowed to pay their tributes in coin, gold, or products, as they may choose. 51. Another section of the said memorial also pointed out that, although certain Spaniards of tender conscience have freed their slaves, native to the said islands, in fulfilment of the provision of my decrees, many others have retained them, and do not allow them to have houses of their own, or to live on their own land under the ordinary instruction. It is advisable to remedy this also; and I therefore commit it to you, and order you that, immediately upon your arrival at the said islands, you shall set at liberty all those Indians held as slaves by the Spaniards.
