Supposing that the number of miles or leagues corresponding to each degree were to be verified by the care and skill of the men abovesaid, then another very long and difficult calculation would be necessary, namely, the appointment of experienced men to measure and determine the number of measures or degrees from one continent or province to another. And when they shall reach the half [one hundred and eighty degrees] counting from the line passing at the end of the three hundred and seventy leagues, at that place they shall establish a point or mark to show what pertains to each side. But as this manner of measuring degrees may be difficult from east to west, although easy from north to south, recourse must be had to certain fine and subtile methods, of which, although everybody is well informed concerning them, I shall not hesitate to state a few facts I have been able to acquire, in order to give these other deputies an opportunity to explain those facts of which I am ignorant. [Various methods for estimating the length of a degree follow. Colon concludes thus:] But inasmuch as the determination of the above methods seems to be and is difficult, each one of them must be employed, and each one put into execution, so long as one does not conflict with the other. Furthermore the day's run must conform to these methods, and pilots of great experience and judgment chosen. In this way it might be hoped to determine a division in which neither part would suffer and great loss or inconvenience. Inasmuch as, in another form, _rebus stantibus ut nunc_, I consider it impossible that one side can succeed in convincing the other by demonstrating that the Malucos fall within his territory, although one might show that it is more in accordance with equity and reason, and thus obtain his object, if the judges imagine that they could determine it according to rigorous and absolute judgment; therefore in order to accomplish my utmost as well as to do everything that I think can be of use in this question, upon the day determined by the assembly I shall present in writing all the evidences, documents, and drawings bearing upon this case that, to my mind, might prove useful. Now to sum up in conclusion of the above, neither side can convince the other that he is trying to shift his ground; and therefore, I say, no sentence can at the present time be passed upon this case, except that it will be necessary to agree upon an expedition to compute the size of the degrees; and this done, ships and men must be chosen, for the purpose of measuring the longitude by one or the other of the various methods found to be best, and for definitely determining and marking the beginning and end of the said demarcation, and the lands falling in each part or hemisphere.
