MEETINGS. 63 



REPORT OF THE GEOLOGICAL SECTION. 



Although the construction of drains has been extensively 

 carried on during the past year both in the parish of St. 

 Peter-Port and in that of St. Sampson's, the excavations 

 have not revealed any very striking features. The oppor- 

 tunities offered by the summer excursions of the Society have 

 not been numerous. 



SUPERFICIAL ROCKS. 



JRohais, Foulon and Colling s Roads. 



Superficial deposits are rather poorly represented in these 

 districts. Deposits of yellow earth occur in a few localities 

 but are nowhere very thick. In most places the decomposed 

 rock is found immediately under the soil. In Collings Road 

 this decomposed rock is generally pseudo-stratified, but the 

 excavations being along the strike of the strata, they do not 

 show so well as they did in Camp Pendart. 



Banks. 



The excavations from Red Lion to near Heronniere 

 were in shingle and sand, doubtless forming part of the 

 modern beach, and overlying a silty clay near the junction 

 of the parishes. Near Heronniere the decomposed rock crops 

 up with a capping of head, consisting of angular pieces of 

 diorite in clay. From this spot to the bottom of Mont 

 Morin Lane, this deposit of head continues, being from Pike's 

 Corner overlaid by yellow earth with occasional sandy 

 patches, but nowhere exceeding 5 or 6 feet in depth. 



Anneville and Noirmont. 



The Old Capelles Beach is exposed in the " chasse " or 

 passage leading to Anneville, and shows pebbles resting on 

 coarse sand or gravel. We were informed by the proprietor, 

 Mr. Mahy, that the deposit is in places 10 feet deep, and that 

 some of the beds are of fine white sand. We could not see 

 the base of the deposit, but the beach at Noirmont which is 

 on the same level and doubtless of the same period, rests on 

 head. In this it differs from the beaches seen at lower levels, 

 which rest on decomposed rock and are overlaid by head. If 

 the head in both cases is contemporaneous, it would follow 

 that the upper beaches are more recent than the lower ones, 

 and the following series of movements at least would be 

 required to account for the order of the deposits : —
