generally at the foot of the slope. It is unnecessary to refer to 

 other than t}^ical deposits ; but the extent ot these Gravels is 

 considerable ; probably there is not a valley in the Cotteswolds 

 in which they do not occur, often forming a narrow belt along 

 the hill side except where intersected or broken by a running 

 stream or combe. 



Mr. Lucy attributes the transport and deposit of the Gravel 

 to the sliding of land ice and snow. I do not think this 

 explanation is sufficient, for the following reasons : — 



(1) — The detritus, if formed and carried down the slopes by 

 land ice, would, to some extent, be worn and smoothed, but the 

 Gravel has not any such appearance. 



(2) — Where the Gravel is found near the ridge of a long 

 spur, there could not have been any gathering ground for a 

 sufficient accumulation of snow or ice to form sliding masses, 

 and no detritus could be brought into such a position by moving 

 ice. 



(3) — At Hyde the Angular Gravel has been brought from 

 the slope of the Great Oolite over the Fuller's Earth, the 

 sui'face of which is nearly flat, and deposited on the edge of the 

 escarpment of the Inferior Oolite, which has a steep slope 

 immediately below. It is difficult to conceive how a mass of 

 moving snow or ice could be arrested in its progress just at the 

 spot where the incline became so much greater. Yet, if Mr. 

 Lucy's explanation is correct, this must have happened year 

 after year until a gravel bed of considerable thickness was 

 deposited. 



(4) — The deposits at Longfords Lake show no trace of ice 

 action. If masses of ice came down the slope upon the Gravel 

 bed, then in course of deposition, the regular arrangement of 

 rolled and Angular Gravels, as seen in the section, would 

 have been distm-bed, and the two Gravels mixed up together. 

 The ice would also have carried down whatever rubbish the 

 frost had previously broken up, and we might expect to find the 

 deposit made up of blocks of stone, varying in size, with 

 Gravel and detritus generally, whereas it is a characteristic 

 feature of the Gravel at Longfords, and generally elsewhere,
