![EOCENE TERTIARIES. I lie small tract of Bag shot Sand in Slieppey is unimportant; but the effect of water passing through it (including the over- lying gravel) may be seen at the cliff eastward of Minster, where the springs from these permeable beds aid in the loss of. land. The sandy members of the Lower London Tcrtiavies have small springs, where clayey beds intervene; but here again none are important. There are some springs in the broad tract of Thanet and Woolwich Beds round Ash, the clayey lower part of the Thanet Beds holding up the water in the sands above. Mr. G. Dowker has remarked that “ springs issue near the ‘ Sportsman/ [at Cliffsend, west of Ramsgate] and from the Thanet beds of Pegwell Bay cliff . . . apparently from the Tertiary beds/’f1) One of the former is named St. Augustine’s Well, on the Ordnance Map, and another is marked at Cot- tington Bridge, under the railway to the north-west. Close to Faversham there is a spring in the large pond just south of St. Mary Magdalene Church, Davington; but this is likely to be of Chalk-water, coming up through Thanet Sand. The same may be the case with the springs in the still larger pond at Davington Powder Mills, to the N.W. and with the spring feeding that pond, which rises just S.W. of it. A little north-westward there seem to be springs from the sand of the Thanet Beds, a quarter of a mile east of Ludden- ham church, and about half that distance south of the church. There is a funnel-shaped spring, apparently from a like source, nearly half a mile eastward of Teynham church. It will be seen, from the account of Chalk-springs, that there is often doubt as to the origin of the water in these parts : one is in doubt, indeed, how to classify some of the springs at Tonge, Bapchild, etc. Some powerful springs rise in the low ground of the out- crop near Newington, some way from where the Chalk comes to the surface. Prof. Hughes was therefore justified, at the time he described these,(2) in trying to account for them as Tertiary springs; but a later examination by Mr. Topley and myself, when we were expressly studying the springs of northern Kent, led us to conclude that the water, or at all events most of it, really came up from the Chalk, through the Tertiary beds, and these springs will, therefore, be noticed further on. The highest spring known seems to be of Tertiary origin (see p. 37). At Gore, more than half a mile south of the church at Upchurch i§ a small spring, in Thanet Sand, a little below the 50 feet contour, giving rise to a little stream. In the western part of Kent, where the Woolwich Beds nearly always contain distinct clayey beds, water is thrown ’ Qeoil.
