And whereas some of the aforesaid merchants deal in other merchandise as avoir-du-pois and other fine goods, such as cloths of Tars, silk, cendals and other diverse wares, and horses also and other animals, corn and other goods and merchandise which cannot easily be put at a fixed custom, the same merchants have granted to give us and our heirs on each pound of silver of the estimation or value of such goods and merchandise, by what name soever they be known, 3d. in the pound at the entry of those goods and merchandise into our realm and power aforesaid within fifteen days after such goods and merchandise shall have been brought into our realm and power and there unladen or sold; and likewise 3d. on each pound of silver at the export of any such goods and merchandise bought in our realm and power aforesaid, beyond the ancient customs before given to us or others; and touching the value and estimation of such goods and merchandise whereon 3d. on each pound of silver, as is aforesaid, are to be paid, credit shall be given to them by the letters which they shall show from their lords or fellows, and if they have no letters, it shall stand in this behalf by the oaths of the merchants, if they be present, or of their yeomen in the absence of the same merchants. It shall be lawful, moreover, for the fellows of the fellowship of the merchants aforesaid to sell wools within our realm and power aforesaid to other their fellows, and likewise to buy from the same without payment of custom, so, nevertheless, that the said wools come not to such hands that we be defrauded of the custom due to us. And furthermore it is to be known that after the said merchants shall have once paid in the form aforesaid in one place within our realm and power the custom above granted to us for their merchandise, and have their warrant thereof, they shall be free and quit in all other places within our realm and power aforesaid of payment of such custom for the same merchandise or wares by the same warrant, whether such merchandise remain within our realm and power or be carried without, except wines which shall in no wise be taken out of our realm and power aforesaid without our will and license, as is aforesaid. And we will, and for us and our heirs we grant that no exaction, prise or prest or any other charge be in any wise imposed on the persons of the merchants aforesaid, their merchandise or goods, against the form expressed and granted above.
