vigilance must be exercised to see that the natives do not cut the anchor-cables, and thus send the ship adrift.  To guard against treason and poison, invitations to festivities or banquets must not be accepted, nor shall any food be eaten unless the natives partake of it first.  If no settlement can be made because of the unwillingness of the natives, or because of the scarcity of men, then the expedition—­the entire fleet, if Legazpi deem best—­shall return, after having first made peace and friendship, trying to bring enough treasure, etc., to pay the expenses of the expedition.  It is advisable to leave some of the priests in any event, “to preserve the friendship and peace that you shall have made.”  If any Portuguese are met among the islands of Japan, part of which lie in Spain’s demarcation, any hostile encounter must be avoided, and the Spaniards must labor for peace and friendship.  In case they obtain such peace and friendship, then they must try to see the charts carried by the Portuguese.  Whether the latter are found or not in these Japanese islands, Legazpi must try to ascertain whether any Theatins [45] have been sent thither to convert the natives.  Finding these latter, information as to those regions and the actions of the Portuguese therein must be sought.  In case the Spaniards and Portuguese come to blows, and the victory remain to the former, a few Portuguese prisoners shall be sent to New Spain.  If the Portuguese have unlawfully entered the limits of Spain, Legazpi shall, with the advice of his captains and the royal officials, take what course seems, best.  If vessels are encountered in the Japanese archipelago or in districts contiguous thereto, Legazpi must try to effect peace and friendship, declaring that he was compelled to enter those districts because of contrary winds; he must gather all the information possible from them, concerning themselves and the Portuguese.  Should these vessels thus encountered prove to be armed fleets or pirates, any conflict with them must be avoided.  In case of a fight, let him depend on his artillery rather than on grappling.  Any prisoners must be well treated, “and after having gained information of everything that seems best to you, you shall allow them to go freely, giving them to understand the greatness of the king, ... and that he wishes his vassals to harm no one.”  Pirates are to be dealt with as shall be deemed best.  All trading must be at the lowest possible price, and fixed figures shall be established.  Native weights must be used.  The royal officials are to have entire charge of all trading, of whatever nature, and no individual shall presume, under severe penalties, to trade for himself, for in that case prices will be raised by the natives.  These officials shall trade first, merchandise to the value of fifty thousand pesos of gold dust [46] for the king, and then ten thousand pesos for private individuals; then another fifty thousand for the king, and so on; but
