possession or quasi possession, and as regards the proprietorship, howsoever and in whatever manner they belong to him, as if this contract were not made, and in the manner in which they first held possession and claimed to hold it, and this contract shall cause no prejudice or innovation. _Item_: It is covenanted and agreed by the said attorneys, in the names of their said constituents, that, in order to ascertain what islands, places, lands, seas, and their rights and jurisdiction, are sold, henceforth and forever, by the said emperor and king of Castilla, by this contract under the aforesaid condition, to the said King of Portugal, a line must be determined from pole to pole, that is to say, from north to south, by a semicircle extending northeast by east nineteen degrees from Maluquo, to which number of degrees correspond almost seventeen degrees on the equinoctial, amounting to two hundred and ninety-seven and one-half leagues east of the islands of Maluquo, allowing seventeen and one-half leagues to an equinoctial degree. In this northeast by east meridian and direction are situated the islands of Las Velas and of Santo Thome, through which the said line and semicircle passes. Since these islands are situated and are distant from Maluquo the said distance, more or less, the deputies determine and agree that the said line be drawn at the said two hundred and ninety-seven and one-half leagues to the east, the equivalent of the nineteen degrees northeast by east from the said islands of Maluquo, as aforesaid. The said deputies declare that, in order to ascertain where the said line should be drawn, two charts of the same tenor be made, conformable to the chart in the India House of Trade at Sevilha, and by which the fleets, vassals and subjects of the said emperor and king of Castilla navigate. Within thirty days from the date of this contract two persons shall be appointed by each side to examine the aforesaid chart and make the two copies aforesaid conformable to it. In them the said line shall be drawn in the manner aforesaid; and they shall be signed by the said sovereigns, and sealed with their seals, so that each one will keep his own chart; and the said line shall remain fixed henceforth at the point and place so designated. This chart shall also designate the spot in which the said vassals of the said emperor and king of Castilla shall situate and locate Maluquo, which during the time of this contract shall be regarded as situated in such place, although in truth it is situated more or less distance eastward from the place that is designated in the said charts. The seventeen degrees eastward shall be drawn from the point where Maluquo is situated in said charts. For the good of this contract the said King of Portugal must have said chart, and in case the aforesaid be not found in the House of Trade of Sevilha, the said persons appointed by the said sovereigns shall make said charts within one month, signed and sealed as aforesaid.
