Beds, although near Godalming and Guildford, where that clayey 

 division is not recognized, the Bargate Beds have been grouped by 

 some geologists with the Folkestone Beds. 



The palseontological zones in Gault and Upper Greensand are dealt 

 with as fully as possible, the zone of Hoplites lautus not being 

 distinguished from that of H. tnterruptus, and that of Pecten asper 

 not being clearly established. The Chalk zones are fully represented 

 up to that of Actinocamax quadratus, and there is a good tabular list of 

 all the fossils. 



Only one outlier of Reading Beds has been observed near East 

 Stratton, and there an imperfect section shows about 10 feet of sand 

 and loam, with pebbly basement-bed and a covering of Clay-with-flints. 



Greywethers occur in various places, some pebbly, and the author 

 remarks that " There appears to be no good grounds for referring any 

 of the local sarsens to the Beading Beds ". On the other hand, it may 

 be said that there are no good grounds for not regarding them as 

 derived from that formation. 



The author has given careful attention to the tectonic structure 

 and the system of gentle folds, the principal and minor anticlines and 

 synclines being shown on a sketch-map. These have influenced the 

 topography indirectly, and their relation to the various streams and 

 rivers is briefly discussed. 



With regard to the Clay-with-flints the author observes that while 

 it is largely made up of debris of Beading Beds, " it rests indifferently 

 on surfaces which may be four or five feet, or four or five hundred feet, 

 below the Eocene basal plane," and "may be said to be in process of 

 formation at the present day" under the solvent action of rain. 

 He agrees with Mr. Jukes-Browne "that much of this deposit, in its 

 present form, is a result of vigorous soil-cap movement, occurring 

 under sub-arctic conditions, during late Pliocene and early Pleistocene 

 times ". 



Three small patches of stony sand and loam 370 to 390 feet above 

 Ordnance Datum occur on the Gault in the north-eastern part of the 

 area ; and these, the only representatives of ' Plateau Gravel ', in 

 the opinion of the author "may be correlated with the Palaeolithic 

 deposits of Farnham Common ", further to the north-east. 



The Biver Gravel, Bain- wash, and Alluvium are described, and there 

 is an interesting chapter on Economic Geology. Remarks are made on 

 the soils and land dressing, there being a marked connexion between 

 the soil and subsoils, and the agricultural features. Building and 

 road materials, springs and water-supply also receive attention.
