Aliuvf the apparent liead <>( tin- tit'tli valU-v east of SaiMlrin^-liani 

 statioii-. there is on the same line a long valley Avith iiu nutlet, 

 terminating in a lagnon cast <>\' the golf club house. A tlatti-ning 

 of the grade of all these valleys mi iirs about the line of the IJluft"- 

 rcail. and on the same line ocinis the flattest part of the Klstern- 

 wii'lv Ci'eek (except its head and swamps at the mouth). The 

 grades of the valleys are shown in the accompanying table in whieli 

 the letter D indicates tliat the valley is here diverted south-west, 

 and the letter B that it is blocked with no free outlet.

The ridges between the valleys show a gradual descent with 

 few irregularities. On a si'ction at right angles to the valley the 

 south-west side is nearly always lower than the north-east. Taking 

 the general level of the ridges the fall is on the whole west, not 

 north-west. All the departures from regularity in these valleys 

 are the few diversions to the south-west and the loss of giade, 

 producing swamps. Xuniemus ill-drained or undiaine(l areas 

 occur about the heads of the valleys near (Jheltenliam, and as far 

 "West as close to the Red Bhifit, Sandringham. These are usually 

 very closely related to, or actually part of, the valleys. Tlie high
