of Nueva Espana or in any other of his ports.  It is understood, however, that, when such necessity ceases, they shall immediately set sail and return to their part of the southern seas.  Should the aforesaid subjects cross said line through ignorance, it is herein covenanted and agreed that they shall incur on that account no penalty whatsoever, and as long as it is not fully evident that they know themselves to be within the said line, they shall not turn about and go outside of it, as is covenanted and agreed in case of entering on account of tempestuous and contrary winds or necessity.  But, when such a fact is quite evident, if it shall be proved that they have entered the line maliciously, they shall be punished and dealt with as those who shall enter the line as aforesaid and as is set forth in this contract.  Should the aforesaid discover any islands or lands, while navigating within the said line, such islands or lands shall belong freely and actually to the said King of Portugal and his successors, as if they were discovered, found, and taken possession of by his own captains and vassals, at such time.  It is covenanted and agreed by said deputies that the ships and vessels of the said emperor and king of Castilla and those of his subjects, vassals, and the natives of his kingdoms, may navigate and pass through the seas of the said King of Portugal, whence his fleets sail for India, only as much as may be necessary to take a due course toward the strait of Magalhanes.  And if they violate the abovesaid, and sail farther over the said seas of the said King of Portugal than is mentioned above, both the said emperor and king of Castilla, if it is proved that they did it by his order, countenance, aid, or consent, and those sailing in this manner and violating the abovesaid, shall incur the above penalties, in the completeness set forth above in this contract.

Item:  It was covenanted and agreed that if any of the subjects of the said emperor and king of Castilla or any others shall henceforth be seized and found within the said limits above declared, they shall be imprisoned by any captain, captains, or subjects whatsoever of the said King of Portugal and shall be tried, chastised, and punished as privateers, violators, and disturbers of the peace by the said captains.  Should they not be discovered within the said line, and should afterwards come to any port whatever of the said emperor and king of Castilla, his majesty and his justices shall be obliged to seize and imprison them, until the warrants and testimonies sent by the said King of Portugal, or his justices, shall have been presented.  If proved guilty of the aforesaid offenses they shall be punished and chastised to the limit as evil-doers and violators of the faith and peace, and of everything else set forth in this contract in regard to the crossing of said line by any subjects of the said emperor and king of Castilla, or any others by his command, consent, favor, or aid.  It is
