    TFic G^jf{t(Atlon of Uic Scale. For the Stour. TheLeJJer Waters [96] it. The Low-water mark then at the Bar of the Haven is the Beginning of the Scale. From whence as you go up the River, it riles to 9, 18, 27, 3<5, and fo on in a Gradual elevation quite up to the two Heads of the River atLenham and Poftling, whole heights are 6 21 and 49 5 ; and even to the Ridge of the Down-hills juft above them, that mounts up to 783 and 763 ; which are the Higheft hills of the Coun¬ try, and the boundary of the two General Regions of North and South Eaft Kent. All the Figures that relate to the Aftiford vale and the Stour-dale, i. e. to the whole Rife and Courfe of the River Stour, Refer to the Low-water mark attheBar of theHavenj but there are Lefler calculations made for the Lefler fyftems of Waters; whofe Figures belong to the High-water marks of other various parts of the Sea. On the Weji of Boughton-hill are the Sittingbourn and FaverfhamCreeks; and the Grav’ny, Sea-Salter and Whitftable Brooks; On the Eaft fide in the Hern Vale the Swakely and Hern-Bay Brooks: And in the S. E. on the other fide of the Coaft beyond the North Foreland, the Courfe of the Nail bourn into the River Dure at Alkham; and of that down by Ewell and River into Dovor-Harbour, are fign’d with thefe Figures. And Lower ft ill, on the other fide of the South Foreland; the Rife of the waters under the great Down-hills, and their Courfe thro3 their feveral Channels athwart the Folkftone Vale into the Sea are all mark'd in the fame manner. By this means you have not only a general, but a particular, and a Com¬ parative view of all the parts of this Country that as well their Ahfolute heights above the Level of the Sea at High- water mark, as their RefpeBwe that relate both to the Waters of the Stour and to one another, all appear in a very intelli¬ gible manner. The Reafon Why I have made all thefe Lefler calculations from the///g^inftead of the Low-watermark is* . that
