whether he claims anything in the vill not named, and similarly the tenant, whether  he claims anything in the vill named. If they say they do not, the assise falls, but not  the writ, but without any other writ let rightful boundaries at once be drawn between  the vills or the manors.1 Let the same be done if there is disagreement as to the  boundaries and limits of counties, as where the tenant says it is in one county and the  plaintiff that it is in another, and as to that both put themselves on the jury. [If] the  jurors know the boundaries and limits of the counties, by their oath let the matter  proceed; if they say that the tenement is in the county not named, the writ falls and  the matter will proceed by another writ, in the way described above; if they say it is  in the county named, the assise will proceed and the matter be determined by the  assise. If the jurors do not know the boundaries and limits of the counties, the writ  does not fall on that account, but the assise falls into a perambulation,2 without any  other writ, by direction of the judge acting ex officio, and that will determine the  matter, [Provided, as was said above, that the parties are first brought to an issue  certain, that it be inquired3 of the plaintiff whether he claims anything in the county  not named, and conversely of the tenant, whether he claims anything in the county  named,]4account being taken of whether the plaintiff is of full age or a minor, for no  minor may consent to a perambulation, and thus, lacking consent, it will not proceed  until his full age. If the jurors say and well know that part of the tenement of which  the view has been made is in the vill or county named, and part is not, the assise will  proceed as to the part within the vill or5 county, not the other, and let both parties  be in mercy.
The assise falls into perambulation.
 Because of uncertainty an assise falls into a perambulation, by consent of the parties  in the manner aforesaid, as where there is a dispute between them as to the barony or  the fee in which the tenement is, and the jurors do not know where to place it, and  thus by the perambulation the dispute will be determined. Sometimes a perambulation  is had between the lord king and a plaintiff, as where a disseisin has been committed  by the bailiffs of the lord king in his name. If it is manifest, the pleasure of the  lord king must be awaited as to whether the assise may proceed or not.6 If it is  uncertain
