Harrison explains his method of naming rivers. In his own eloquent words in Holinshead’s Chronicles Volume one: 1587
“For such hath beene my help of maister Sackfords cardes, and conference with other men about these, that I dare pronounce them to be perfect and exact. Furthermore, this I have also to remember, that in the courses of our streames, I regard not so much to name the verie towne or church, as the limits of the paroch. And therefore if I saie it goeth by such a towne, I thinke my dutie discharged, if I hit vpon anie part or parcell of the paroch. This also hath not a little troubled me, I meane the euill writing of the names of manie townes and villages; of which I have noted some one man, in the description of a riuer, to write one towne two or three manner of waies, whereby I was inforced to choose one (at adventure most commonlie) that seemed the likeliest to be sound in mine opinion and iudgement.”
