342 Mr. Horner on the Geology of the 



The western extremity, which I did not measure, judging from its 

 appearance at a distance, can be very little less than this height. 



The Quantock hills when viewed from a distance, present 

 a gently undulating outline, which rises in three places into a more 

 prominent elevation, the most northern being called Doucebury,^ 

 the central height Will's Neck, and the most southern Cothelstone 

 Lodge, from which last point the range diverges, as has been al- 

 ready noticed. Will's Neck is the highest of the three, and was 

 measured at the time of the Trigonometrical Survey, and found 

 to be 1270 feet above low water. It is called in the Survey the 

 Bagborough station, being immediately above the village of that 

 name. Doucebury I found by the barometer to be 1022 feet, and 

 Cothelstone Lodge 1060 feet above low water mark ; but as both 

 these measurements were made under very unfavourable circum- 

 stances, they are not to be relied on. Doucebury must be consi- 

 derably higher than I found it to be ; the measurement of Cothel- 

 stone Lodge is probably not very far from the truth, judging in 

 both cases from the comparison between the three heights when 

 seen at a distance. 



§ 4. The whole of the mountainous part of this district is 

 formed of a series of rocks differing very considerably in mineralo- 

 gical characters, but which the repeated alternations of the several 

 varieties, and the insensible gradations that may frequently be 

 traced of one into another connect into one common Jon?iaiion, A 

 great proportion of these have the structure of sandstones, the 

 component parts varying in size from that of mustard seed to such 

 a degree of fineness, that the particles can with difficulty be dis- 

 cerned. Quartz and clay are the essential component parts of all 

 the varieties, but in different proportions. The quartz in some

 Danesborough in the Ordnance map.
