The River Smithford to Lyell 



above and added to the stock of material for examination 

 in the laboratory. 



Continuing our journey towards the north, the 

 valley soon commenced to widen, the hills falling back 

 on either hand until, arrived at the town of Red River, 

 we found ourselves in the centre of an alluvial flat not 

 dissimilar from that at Smithford. 



Looking back towards the gorge, we saw stretched 

 right and left, as far as the eye could reach, a long 

 escarpment or range of hills with a steep scarp face, 

 through which the gorge that we had just left was the 

 only visible opening. 



Once more in the laboratory we proceeded to un- 

 pack our collections, and found ourselves possessed of 

 numerous fossils from the Chalk, Upper Greensand, 

 Gault, and Lower Greensand, hollow flints from the 

 Chalk and a quantity of the powdery matter from the 

 cavities in their interiors, specimens of the various rocks 

 encountered, including white sand from the Lower 

 Greensand and several boxes of grains from the red 

 beds together with a bag of pebbles from the same 

 source. 



All the above we carefully numbered and made a 

 record of the formation from which they had been 

 collected, the exact locality, and the conditions under 

 which they had been found. 



As some of the materials of the upper beds may 

 have been derived from the lower ones, we examined 

 the latter first so as to become thoroughly familiar with 

 their appearance in order that, should we encounter 

 them in the newer deposits, we should be able to recog- 

 nize them.
