THE GEOLOGIST. 



the beds of sand become of course more visible, and near the com- 

 mencement of the road to St. Addresse, a most excellent section is 

 presented, the measurement and description of which is subjoined : 



Section of Gravel and underlying Sand at St. Addresse. 



ft. in. 



Vegetable soil 3 ? 0 



Geayel — Eed, sandy, flint-gravel, drift 10 ? ft. and upwards ? 



Sand Deposit — Very friable, slightly adhesive, fine sand-rock, with lines of 



dark-green grains, and becoming slightly ferruginous at the base ; 



crumbles in the hand 5 0 



Band (more sandy than above) of shells of all ages and sizes, irregularly 



bedded, principally of Cardium edule 0 9

Band of small pebbles and comminuted shells 2 0 



Besting on dark-blue argillaceous sand, intermixed at top with dark- 

 grey sand . 14 



Grey argillaceous sand, semi-consolidated, containing at 28 in. from 



top a band of shells, Cardium edule, etc., with small univalves.

The shells found were principally those of the common cockle and 

 Tellen, and these, though sometimes found in their normal position, 

 were generally in the disorder and confusion so characteristic of 

 littoral accumulations as to leave no doubt of the beds in question 

 having formed at some former period a portion of the shore. The 

 above-mentioned species of shells occurred in abundance, and no 

 doubt a minute examination would add others to the list. 



This portion of the section abuts against a great mass of crate glau- 

 coneuse and rubble, which almost seems to have parted the stream of 

 flint-drift that surmounts the sand beds. The section from hence to 

 the commencement of the cliffs of the Cape, consisting of a lofty sloping 

 bank, is rendered extremely obscure by the vegetation which so luxu- 

 riantly covers it. There seems at places to be indications of sand, 

 but whether the bed alluded to is continued, required more time and 

 a more minute investigation than I had it in my power to bestow. 



The existence of a bed of sand with recent shells below the flint- 

 drift is a curious fact, if correct and I am not deceived by appear-
