First:  in order that you may go well-informed, the instructions and agreement made with our said captains for the voyage of discovery are as follows: 

I, the King.  Inasmuch as you, Fernando de Magallains, knight, native of the kingdom of Portogal and bachelor Ruy Falero, also native of said kingdom, wish to do us signal service, binding yourselves to discover within the boundaries which pertain to and belong to us in the Ocean Sea, within the limits of our demarcation, those islands and mainlands, riches, spices, and other things with which we shall be well pleased and these our kingdoms well profited, we order herewith the following agreement to be made with you: 

First:  in order that you may and shall with good fortune go on a voyage of discovery in that part of the Ocean Sea within our limits and demarcation; and as it would not be just that since you are going yourselves to perform the aforesaid, other persons should venture to do the same; and considering that you are to have the hardship of this enterprise:  it is my will and pleasure (as I now promise) that, for the term of the first ten years ensuing we shall not permit any other person to go on a voyage of discovery by the same route and course that you may take; and that if anyone else should wish to undertake it and ask permission, it shall not be granted until you have been informed thereof, so that, if at the same time you should so desire, you may undertake it also, being as well prepared, equipped, and furnished with as many vessels as equally well-conditioned, equipped, and manned as those of the other persons wishing to make the said discovery.  But it is to be understood that if we should wish to order or permit other persons to undertake such an enterprise by the western route, in the district of those islands, with Tierra Firme and all other places already discovered, towards the desired direction, for the purpose of seeking the strait of those seas, we may so order or permit to these others.  If they should wish to start on their discoveries from Tierra Firme or from the island of Sant Miguel, and go through the southern sea, they may do so.  Likewise if the governor or people who, by our mandate, are now, or may be in the future, in the said Tierra Firme, or any others of our subjects and vassals should wish to set out on a voyage of discovery in the southern sea, wherein such discovery is permitted; and if they wish to send out ships for further discoveries; then our said governor, vassals, and any other persons who, according to our pleasure, should go upon such discovery in that direction, may do so, notwithstanding the aforesaid of any section and clause whatever in this agreement.  But we also desire that if you should wish to do so, you may discover by any of these said routes, provided the place be not already discovered or found.

The aforesaid discovery must be made in such manner that you do not discover or do anything to his prejudice, within the demarcation and limits of the most serene king of Portogal, my very dear and well beloved uncle and brother, but only within the limits of our demarcation.
